Are Cell Phones Causing Cancer?

In 1993, a man filed a lawsuit against the cell phone industry, claiming that his wife died from a brain tumor caused by her repeated use of the cell phone. The tumor was on the same side of the head where she held her cell phone and was shaped like the cell phone antenna. The case got widespread media attention and was featured in CNN’s Larry King show.

Although the claim was dismissed by the court due to lack of sufficient evidence, it was a public relations nightmare for the wireless industry. It also marked the beginning of the global search for a definitive answer to the question: are cell phones safe or not? Does it cause cancer and other degenerative diseases? Brain cancer is up 25% since cell phones became popular. Every year, there are 183,000 more cases in the US alone. Some health experts say there’s a link with cell phone use, but is there proof?

In an effort to diffuse the negative publicity from the high-profile lawsuit, the cell phone industry itself funded a $25 million dollar research program to prove that cell phones are safe. After 6 years of intensive research, however, the results were not what they were looking for. Dr. George Carlo, the chief research scientist of the program, found evidence that cell phones pose some health risks, possibly even cancer.

The first evidence of cancer link that shook the cell phone industry came in 1997. Dr. Michael Repacholi and his colleagues from the Royal Adelaide Hospital in South Australia reported that long-term exposure to the type of radiation that comes from digital cell phones caused an increase in the occurrence of lymphoma in mice. The study received widespread international media attention because it was the first time that cancer has been linked to the cell phone in a well-conducted study.

THE RED FLAGS: SOLVING THE CANCER PUZZLE
In order to show a link between cell phone radiation and cancer, let’s look at several studies Dr. Carlo investigated that made him blow the whistle, so to speak. These red-flag findings provide the pieces that fit together to form the cancer picture:

– DNA Damage in Human Blood Studies
– Breakdown in the Blood-Brain Barrier
– Studies of Tumors in People Who Use Cell Phones
– Studies of Cell Phone Radiation Dosage and Response

DNA DAMAGE IN HUMAN BLOOD
All tumors and all cancers are the result of genetic damage. Most often that damage includes the formation of micronuclei–fragments of chromosomes that form membranes around themselves and appear under a microscope as additional nuclei in blood cells (which normally have just a single nucleus). The relationship between micronuclei and cancer is so strong that doctors around the world test for their presence to identify patients likely to develop cancer. The presence of micronuclei indicates that the cells can no longer properly repair broken DNA. This deficiency is considered to be an indication of an increased risk of developing cancer.

– In December 1998, Drs. Ray Tice and Graham Hook of Integrated Laboratory Systems in North Carolina have shown that blood cells exposed to cell phone radiation suffer genetic damage in the form of micronuclei. In their studies, DNA and chromosome damage in human white blood cells occurred when exposed to signals from all types of phones–analog, digital, and PCS. Damage was shown even from signals occurring at a SAR level below the government’s “safety” guideline.

– Using different methods, the above finding was confirmed by Dr. Joseph Roti Roti of Washington University in St. Louis in 2000. His research showed that human blood cells exposed to radiation at wireless phone frequencies did indeed develop genetic damage, in the form of micronuclei. This finding received a lot of notice because Dr. Roti Roti is a prominent scientist who does hiw work under funding by Motorola Inc.

This has a very serious implication. If cell phone radiation encourages the formation of micronuclei in blood cells, and micronuclei are said to be “biological markers” for cancer, then based on these studies alone cell phone use could be said to increase the risk of cancer

BREAKDOWN IN THE BLOOD BRAIN BARRIER
The blood brain barrier is a special filter in the blood vessels of the brain that keeps dangerous chemicals from reaching sensitive brain tissue and causing DNA breaks and other damage.

– In 1994 and again, in 2002, Dr. Leif Salford from Lund University in Stockholm, Sweden found in his studies that rats exposed to cell phone radiation showed a breakdown in the blood brain barrier, as well as areas of shrunken, damaged neurons.

The micronuclei studies of Tice, Hook and Roti Roti and the blood-brain findings of Salford provide a two-step explanation for how cancer could be caused by cell phone radiation.

Step One: A leakage or breakdown in the blood brain barrier would provide a pathway for cancer-causing chemicals in the bloodstream (from tobacco, pesticides, air pollution, etc.) to leak into the brain and damage sensitive brain tissue that would otherwise be protected. These chemicals could break the DNA in the brain or cause other harm to reach those cells.

Step Two: While a number of studies showed that cell phone radiation by itself does not appear to break DNA, the micronuclei findings suggest that they do impair the DNA repair mechanisms in brain cells. Micronuclei result from a breakdown of the cell’s ability to repair itself. If the brain cells become unable to repair themselves, then carcinogenesis–the creation of tumors–induced by chemical toxins could begin.

DNA carries the genetic material of an organism and its different cells. Any damage that goes unrepaired affects the future generation of cells. The change has procreated and this mutation is seen as a possible cause of cancer.

TUMORS IN PEOPLE WHO USE CELL PHONES
Epidemiological studies, performed by different investigators using different methods, show some evidence of an increased risk of tumors among people who use cellular phones.

– In 1998, Dr. Ken Rothman of Eidemiology Resources, Inc. in Newton, Mass., did a study showing that users of handheld cell phones have more than twice the risk of dying from brain cancer than do car phone users–whose antennas are mounted on the body of the car, far removed from the users’ heads.

– In 1998, Joshua Muscat, a research scientist from the American Health Foundation, showed in his study a doubling of the risk of developing neuro-epithelial tumors on the outside of the brain among cell phone users, particularly on the side of the skull where cell phone antennas are held during calls.

– Muscat also showed in another study that people who have used cell phones for six years or more have a 50-percent increase in risk of developing acoustic neuroma, a benign tumor of the nerve that controls hearing and extends from the ear to the brain. Acoustic neuromas can cause hearing loss and can be life-threatening if untreated.

This was confirmed in a separate study in Stockholm, Sweden by Anders Ahlbom in 2004 and sponsored by the World Health Organization (WHO), which finds that people who have used cell phones, this time for at least 10 years, may have an increased risk of developing acoustic neuroma.

– In a study also requested by WHO, researchers headed by Dr. Lennart Hardell of the Orebro Medical Center in Sweden examined 1,617 patients aged between 20 and 80 who had been diagnosed with a brain tumour between 1997 and 2000. They were then compared to healthy people. Those who used cell phones for less than 10 years faced a 20% higher risk of developing brain cancer. But for those who used them for more than a decade the risk was 80% higher. The study also found that tumours were 2.5 times more likely to be on the same side of the head as the phone was held. The cancer of the auditory nerve, acoustic neuroma, showed a larger increase–3.5 times greater risk.

CELL PHONE RADIATION DOSAGE AND RESPONSE
All studies mentioned showed that an increase in cell phone radiation exposure also increases the likelihood of the adverse effect occurring.

In Repacholi’s study of mice, the risk of lymphoma increased significantly the longer the mice were exposed to the radio waves.

In the research work done by Tice, Hook, and Roti Roti, the risks of genetic damage as measured by micronuclei formation increased as the amount of radiation increased.

In the three epidemoiological studies–two by Muscat and one by Hardell–the risk of tumors was greater in the areas of the brain near where the cell phone was held.

In Salford’s study, the higher the radiation exposure level the rats were exposed to, the more damage was apparent in the blood vessels in the brain and the neurons.

THE BIG CANCER PICTURE
The test tube studies by Tice and Hook; the mouse study by Repacholoi and Selford; and the epidemiological studies by Rothman, Muscat, and Hardell all agree in that they suggest an increased risk of cancer among cell phone users. They fit together to form the beginnings of a picture that everyone can see. They perhaps don’t form the complete picture yet, but there are enough already in place to see that there is cause fo genuine public health concern about cell phone safety.

According to Dr. Carlo, “The big picture is disturbingly clear. There is a definite risk that the radiation plume that emanates from a cell phone antenna can cause cancer and other health problems. It is a risk that affects hundreds of millions of people around the world. It is a risk that must be seen and understood by all who use cell phones so they can take all the appropriate and available steps to protect themselves–and especially to protect young children whose skulls are still growing and who are the most vulnerable to the risks of radiation.”

MORE PIECES COMING
– In 2000, a team of Sydney researchers published a scientific hypothesis about how mobile phone radiation causes cancer. The report claims that the radiation generated by cell phones causes ongoing stress to the body cells, causing them to give off ‘heat shock proteins (HSP).’ The human cells sometimes release these proteins in response to injury or infection. Such a chronic activation of the heat shock response affects the normal regulation of cells, which could result in cancer.

– In 2002, cell biologist Fiorenzo Marinelli and his team at the National Research Council in Bologna, Italy, exposed leukemia cells to continuous radio waves similar to that of cell phones. The exposed cells had a higher rate of death than the controls initially, but after further exposure, a curious thing happened: instead of more cells dying, the exposed cells were replicating furiously compared to the controls. Genes that trigger cells to multiply were turned on in a high proportion of the cells. The cancer, although briefly beaten back, had become more aggressive. Marinelli suspects that the radiation may initially damage DNA, and that this interferes with the biochemical signals in a way that ultimately triggers the cells to multiply more rapidly.

SO WHY ARE CELL PHONES STILL AROUND?
Now with all the mounting evidence, the cell phone industry still maintains their position that cell phones are safe and have even begun marketing towards children. The governments have been slow in stepping in to warn people of any danger from using cell phones. Fortunately, health officials and experts in several European countries are taking the first steps, having issued public warnings to parents urging caution about kids and cell phones,

If the previous environmental issues involving tobacco, asbestos, and lead are any indication, it takes years and even decades to accumulate the amount of evidence that would produce a definite ruling. In the case of cigarette smoking, it took two decades of study and 100 years of consumer use to gather enough data to meet research standards to demonstrate the need for the U.S. Surgeon General’s warning label on cigarette packs. Some experts say that in the case of cell phones, it will not take that long as data are coming in at a faster pace. But at the present the authorities can only urge people to exercise caution.

Replication of research is another problem. A study that comes out with a new finding generally does not gain immediate acceptance in the scientific community or the wireless industry unless another research lab has been able to replicate the work and the findings. The industry has cleverly perpetuated their position by creating an illusion of responsible follow up by always calling for more research.

When Dr. Salford published his study in 2003 showing that rat brain neurons were dying from exposure to cellphone radiation, he warned there might be similar effects in humans that over time could lead to degenerative diseases of the brain. His study was written off by the industry as a “novel” finding that needed to be replicated.

But achieving the scientific standard of replication can be complicated. Salford says if studies aren’t absolutely replicated, providing an apples-to-apples comparison, there’s wiggle room to dispute follow-up findings. Research studies require funding, and the wireless industry, after Dr. Carlo’s revelations, have been reluctant to put money into more comprehensive research. As for governments, again many European governments are taking the responsible course by funding research, but the U.S. and Canada are lagging poorly.

In 1999, CNN’s Larry King once again featured a man who brought a multimillion dollar lawsuit against cell phone manufacturers. This time the man, a Maryland neurologist, was himself diagnosed with brain cancer–again located on the side of the head where he held his cell phone. The suit was yet again dismissed, however, and the man died not long afterwards.

According to WHO report, 0.1 billion people have died from tobacco use in the 20th century, and 10 times as many will die in the 21st century. No one is suggesting that cell phones could cause as much casualties, but do we really want to wait and find out?

AIMING FOR RESPONSIBLE TECHNOLOGY
Unlike tobacco, the cell phone has become as an indispensable part of our lives as television and computer. It has enabled us to make a gigantic leap in the way we communicate with one another and has been credited widely with saving people’s lives in emergency situations. Cell phones are here to stay, and perhaps rightly so.

The question is not how to stop people from using this ubiquitous device but rather how to make it safer. The first step always is to admit there is a problem, hence the industry and the government have to acknowledge the health risks inherent with the present technology. This way we can all find the proper solutions that we may more enjoy the benefits of its use without sacrificing our health and wellbeing.

Traveling in Italy and Using Your Cell Phone

You do need a cell phone when you visit Italy. Italy is a GSM country and the networks operate on 900 MHz and 1800 MHz bandwidth, where you will need a GSM handset to make and receive calls. You could take your US cell phone on roaming to Italy through your home service provider, but the outgoing and incoming calls are not cheap and you are bound to run up an outrageous monthly bill. The best way is to rent Italy cell phone from http://www.italysimcards.com and pay a low weekly or monthly rate at a fraction of cost to any other, renting out such phones. Italy cell phone rentals from http://www.italysimcards.com are not only affordable but provide you with the advantage of the cheapest of all rates available, and make your money take you further in your trip to Italy. The rates offered by http://www.italysimcards.com are just fractions of what it would cost you to rent Italy cell phone through conventional sources or roam with your own US cell phone through your home service provider.

To take full advantage of a comprehensive cost saving, a pre-paid Italy SIM card along with your rented Italy cell phone could save you over 80% of your call expenses. When you purchase a pre-paid Italy SIM card, you get a local cell phone number, and all your outgoing calls are charged at local rates. The calls that you receive are all FREE of any charge, no matter where they generate from. Compare this to the fact that when you take your US cell phone on roaming to Italy, you will not only pay for your outgoing call but also for your incoming calls. Since your US cell phone is on roaming through your home service provider, a business agreement has been entered into between your home service provider and the Italian network that you are using while on roaming in Italy. Through this agreement the Italian network provides a US cell phone user. like you, the necessary mobile services and each time you make or receive a call, your home service provider is charged for such service. Not only is that, with you being on roaming, there other charges that your home service provider has to pay to the Italian network provider. This is the reason why you have to pay high charges for your outgoing and incoming calls when you are roaming with your US phone in Italy.

When you rent Italy cell phone, you do not have to pay any roaming charges and with a pre-paid Italy SIM card, you pay for the calls that you make as the locals do and all your incoming calls are absolutely free. At a glance you can appreciate the savings that you have, with Italy cell phone rentals and pre-paid Italy SIM card, which can run up to more than 80% of your communication expenses which you would spend otherwise.

When you purchase a pre-paid Italy SIM card, you get an initial talk time credit. This helps you to use your Italy cell phone right away as soon as you reach Italy. For topping up your talk time credit, you can purchase a recharge voucher, which is available in any of the convenience stores in Italy. You get a choice of values for the amount of credit that you would want. These recharge vouchers are available in many denominations and you have the option to purchase the right amount of credit. You need simply to scratch off the hidden PIN in that voucher and then key in that number to have your credit topped up.

Your pre-paid SIM card for Italy is a small printed circuit board, a little smaller than a postage stamp. It goes into a slot at the back of your rented Italy cell phone and forma the main intelligent module, letting you make and receive calls. SIM stands for Subscriber Identity Module, which has an embedded microprocessor with memories. Your pre-paid SIM card holds your unique information, such as, your phone number, your service plan details, the International Mobile Subscriber Identity (IMSI) of your cell phone SIM card, and more security related details, which are transmitted to the nearest tower as soon as you switch on your Italy cell phone. This information is then matched with the database of the network that you are visiting in Italy. On matching the details, your cell phone is ready to make and receive calls.

Your pre-paid Italy SIM card also has an address book, which holds the name and numbers of the people you call frequently. The SIM card also logs your outgoing and incoming calls, including the ones which you fail to respond. These are all logged along with the relevant time and date of the calls made or received.

The number of mobile subscriptions in Italy has surpassed landline installations. As a result, the network coverage is one of the best in the world, where you will not have any ‘dropped calls’ or have difficult to connect. With your pre-paid Italy SIM card your calls will not be hopping from network to network, since you will be calling through one of the Italian networks. When you but a pre-paid Italy SIM card, you pre-pay for your calls and nothing more is charged to you. With all your incoming calls being FREE and your outgoing calls being charged at local rates, your savings, compared to any other option, are very high. You do not pay for roaming charges and you do not receive any bill at the end of the month. There is no contract for you to sign.

If you wish to take your US phone to Italy, there are three considerations to be made. One is that your cell phone needs to be GSM. Two, even if you have a GSM US cell phone it is unlikely that it will work in Italy. Networks in North America. Canada and a few other neighbouring countries work on different GSM frequency bands than that of the Italian networks. US GSM networks operate on 850 MHz and 1900 MHz frequency bands while Italy operates on 900 MHz and 1800 MHz bands. Unless you have a multi-frequency handset, could be a quad band or tri-band cell GSM phone, you will need a compatible cell phone for your trip to Italy. Italy cell phone rentals from http://www.italysimcards.com are all Italy network compatible and provides you the cheapest solution for your right cell phone in Italy. Third, if you plan to take your US cell phone and carry your number on roaming to Italy through your home service provider, you will need to pay high roaming charges for your outgoing and incoming calls.

You are now already convinced about the fact that Italy cell phone rentals with pre-paid Italy SIM card can save you unbelievable amounts with respect to your communication expenses. When you rent Italy cell phone and purchase a pre-paid Italy SIM card from http://www.italysimcards.com you get a full 24 hour support for the package, for 7 days a week, 365 days a year. What better could be the deal with http://www.italysimcards.com offering Italy cell phone rental at a fraction of a cost than what others offer and a pre-paid Italy SIM card, providing you with an individual saving of up to 80% of your communication costs. You do not pay anything else and since you pre-pay your call charges, you are in absolute control of your expenses.

If you are visiting Italy for the first time, you would perhaps like to know about the country. Italy is a bit larger than the Arizona. It is a long peninsula, shaping like a boat. To its west it has the Tyrrhenian Sea and on the east the Adriatic. The country is encircled by France, Switzerland, Austria, and Slovenia to the north. While the Apennine Mountains forms the backbone of the country, the Alps form the northern border. Italy is a country of beautiful lakes and the largest one is Garda, with Po being its principle river flowing from the Alps, lining the country’s western border and the river crosses Lombard plain to the Adriatic Sea. There are lots of islands which form a part of Italy, the largest being Sicily.
When you are in Italy you will be visiting, Florence, Venice, Rome and the other attractions in the country. You will be taking the Gondola down the Grand Canal, planning to visit one of the finest restaurants in Venice for a delicious Italian preparation. You would perhaps think of watching a show before that. In Rome you will visit the great Colosseum and its mammoth size will make you wonder of the ancient display of strength that went on inside, watched by 50,000 spectators around a central elliptical arena.. It is an amphitheatre, and when you stand in the middle of that great arena, you can almost hear the cheer of that crowd. You would need Italy cell phone to book your seats at the theatre and for table reservations in the restaurant that you want to have your dinner.

Where-ever you are in Italy, you cannot be without your cell phone. You have to be in touch with your associates, friends and family back home and need to be available to those who want to get in touch with you, 24 hours a day, 7 days a week. You need to have a cell phone which is compatible to Italy network conditions with a calling plan which will provide you with a maximum monitory savings. What more could you expect when you go for Italy cell phone rental and a pre-paid Italy SIM card from http://www.italysimcards.com providing you with optimum savings on your outgoing calls, charged at local rates.

Networks in Italy operate on Global System for Mobile Communications (GSM) technology and all Italy SIM cards are compatible with GSM frequency bands. The cell phone that you are taking to Italy needs to be GSM compatible, operating on the Italian network frequencies. GSM is the second (2G) generation mobile telephony technology and is the first digital system. It replaces the old first generation (1G) analog technology. GSM is used over more than 214 countries and has more than 80% of subscribers out of the total number of mobile users in the world. GSM has a set of four frequency bands, 850 MHz, 900 MHz, 1800 MHz and 1900 MHz, which are distributed to the different regions in the world. The GSM frequency bands used by the networks in Northern America, Canada and few other countries in the Americas are quite exclusive to the rest of the world and this sets US apart from the rest of the world regions. It is for this reason that US GSM cell phones are unlikely to work in Italy, unless the cell phone is a multi-frequency handset.
For convenience of travellers, cell phones now come with the features to respond to multiple bandwidths. The quad band phone responds to all the GSM frequencies and can be taken to any part of the world. The tri-band covers three of the four GSM frequency bandwidths, which are 800MHz, 900MHz and 1800MHz. The dual band on the other hand operates on just two frequency bands – 800MHz and 1900MHz.

Your GSM cell phone must be SIM unlocked before any SIM card can be used with it. SIM locked cell phones can only operate with the SIM card that it is meant for and therefore, your handset has to be SIM unlocked for you to use the pre-paid Italy SIM card. When you enter into a contact with your service provider, there may be a clause that might stipulate that you need to be in service with the provider for a specific period of time. In exchange, the service provider offers a cell phone, absolutely free of any cost and this phone is necessarily SIM locked. This is done to ensure that you use the SIM card that you received from the service provider and none else. At the end of the contract period, your cell phone becomes your property and your service provider assists you to SIM unlock your phone. It is then that you may opt for any other SIM card that you may like to use.

Whether you are taking your own US GSM cell phone, buying one or renting, it is imperative that the cell phone that you are taking with you to Italy is SIM unlocked. All Italy cell phone rentals from http://www.italysimcards.com are not only SIM unlocked but are also compatible with the network frequency bands in Italy.

Cell Phone Use and the Risk of Brain Cancer

The use of cell phones has taken the world by storm. From the old to the very young is using cell phones. Many households are without a home phone entirely because the cellular has taken its place. People use cell phones so much that the device has taken on a life of its own. Television networks, movie studios, music industry, and giant internet companies have all capitalized on the cellular telephone to further their objectives.

A few years ago, a multitude of mobile program developers were hired by many companies to build the next generation of mobile phones that would interact with the internet. We are now seeing this come to pass with the high level of performance of today’s wireless mobile units. We can say then that the cell phone is here to stay or is it?

Most would argue that the mobile phone is here to stay but at what cost to our health. Yes, the cellular phone is convenient; that is why we use it. We use the cellular telephone so much that it is causing motor vehicle accidents left and right. That is one of the ways it is affecting our health, negatively of course. Anyone can attest to seeing someone driving while blabbing on the phone; most of the times these drivers are so involved with their conversations that they don’t even know what’s going on around them, in regards to the road and traffic.

It is not rare to see a near-miss and a cell phone talker being at the helm of one of the vehicles. A rule of thumb is to always lookout for drivers on their phones. Make sure the horn works on the vehicle being driven because it may be needed at moment’s notice. Accidents are common among people who talk on their phones and drive at the same time, but is this the only threat cell phone use pose on human health? No! Not according to a National Cancer Institute’s (NCI) study.

Some in the scientific community say cell phone use pose a great risk to human health because it emits radiation in the form of radiofrequency (RF) energy, which has the potential of causing cancer. In fact, no one knows for sure how much radiation is completely safe for the human body. The wireless spectrum is a fairly new technology, so radiation from cellular telephone’s effect on the human body has not yet been extensively studied, (NCI). There simply hasn’t been enough time to see long-term effects of cell phone use-not enough data available.

Why is all the fuss about cell phone use and brain cancer? Well, the answers are here. According to the NCI, cellular telephones emit radiofrequency (RF) energy, which is another name used for radio waves. Exposure to high levels of RF energy causes heating of body tissues, ever wondered why your cell phone becomes hot against the ear when talking for an extended period, enough said! According to the NCI study, the RF energy produced from cellular telephones is too low to cause significant tissue heating and tissue damage.

Studies are currently being conducted of tumors of the brain and central nervous system and other site of the head and neck because the side of the head is where people place their cell phones when speaking. Cell phones are held next to the head when being used. At the moment though, studies have not shown any consistent link between cellular telephone use and cancer. Additional research is needed before firm confirmation can be made, (NCI).

A cellular telephone user is exposed to RF energy through the phone’s antenna. The fact that the antenna of a hand-held cellular telephone is in the handset, it will most likely affect the brain and subsequently the nervous system because it is held against the head. So, the closer the antenna is to the head, the greater the danger of RF exposure. Therefore, a person will absorb less RF energy when the cellular unit’s antenna is at a significant distance away from the user, (NCI).

An important point is that the amount of RF energy increases the farther away the communication tower or base is from the cell phone and its user. In other words, the cellular telephone has to increase its RF energy output when the main tower is far away; thus, introducing a higher degree of radiofrequency radiation to the user. So, the closer the tower to the cellular phone, the less energy is generated by the phone, and therefore, the less radiation the cell phone user will be exposed to. This raises an important question. How can a person avoid dealing with cell phone towers that are too far apart?

One should not be a penny wise and a pound foolish. In general, the cheaper the cell phone plans and services of a new and less establish cell phone company are the lower the overall quality of the service is going to be, in regards to drop calls and such. This means that the towers are going to be farther apart. When the towers are farther apart, the amount of RF energy that will be required to maintain a connection will be tremendously high. All this high degree of radiation will be transmitted directly into the user’s body, especially if the wireless device is held close to the body, such as the head.

It cost wireless phone companies millions of dollars to put up communication towers. So, if a company is going to always offer half price of the going rates of cell phone services, this company will not have the revenue to build many communication towers; thus, the towers that such companies will have will be dramatically less than that of companies with traditionally high levels of cellular telephone services and whom have been around for a long time.

A person will therefore be exposed to more RF radiation with phones from less well-known companies rather than phones with more well known companies because less well-known companies will not have the capital to build many towers as does the more establish and major companies. Yes, the company may be able to offer great cell phone plans and deals; however, the rate of radiation exposure will be much higher. One doesn’t need to be a rocket scientist to see the idea! Therefore, the more popular a less well-known cellular telephone company becomes, the more communication towers it will have and the higher its cellular phone plans will become!

There are more factors that determine how much RF energy a cellular telephone user experiences. Some of these are: number of calls; duration of calls; amount of cellular phone traffic; the size of the cell phone unit itself; and the extended distance of the unit’s antenna, (NCI). In fact, many people speak on the cell phone for very long periods and this definitely is not a good practice. It is best to keep cell phone calls to a minimum. A cell phone should only be used sparingly.

How about the long term effect of cellular telephone use on children and teens? Researchers at the NCI conducted a study to see if children would be more at risk for brain cancers by using cell phones. Persons 18 years and older were used in the study. The study found that there were no possible risks among children who used cell phones. In fact, very few children used cell phone prior to the date of the study. Therefore, there are no data concerning possible risk. Nevertheless, there was concern that certain agents such as ionizing radiation and other chemicals pose great risks in children because they can affect the developing brain and nervous system. However, the study found that the radiation emitted by cell phones has not been demonstrated to cause brain cancers in humans of any age at this present time. More studies are still needed to fully rule out the possibility of cell phone induced cancers.

The bottom line is that wireless phones should be used sparingly because no one knows for sure if they cause cancers in humans. A rule of thumb is to always use a head set or put the cell phone on speaker when speaking, and keep it away from the body at all times when it is turned on. It is always better to be safe than sorry!

The cellular telephone is a great tool for communication. However, it poses great risks to our health-accidents and brain cancers. Accidents have increased dramatically as a result of people talking on their cellular phones and driving. Although, there is no solid evidence to support the claim that cell phones cause cancers, one should still be cautious when using this mode of communication. After all, cellular telephones do emit radiofrequency (RF) energy, a form of radiation that heats up body tissues, which can be harmful at very high levels. Children could also be at great risks for brain cancers from exposure to the radiation emitted by cell phones because certain radiations do cause cancers of the brain and nervous system in children. However, at the present time, there is no evidence to support that cellular telephones cause cancers in children of any age. One should proceed with caution though because although there isn’t any evidence as yet, there could be some in the future. Therefore, to completely rule out such idea more research is needed. The cellular phone technology is very new at this time; therefore, there isn’t enough data available to conduct a conclusive study! The rule of thumb is to use cell phones with extreme caution by limiting the length of time one spends speaking on them. One should use speaker or a hands free device when speaking on cellular phones to limit the amount of (RF) radiation being introduced to the body.
