There have been many scientific studies used to invistigate the possible effects on human health from mobile phone radiations. These studies are usually checked or reveiwed by some scientific committes to assess the overall risks. In 2007 an assesment was published by the Scientific Committee on Emerging and Newly Identified Health Risks (SCENIHR). This assesment concludes that exposure to RF fields is unlikely to lead to an increase in cancer in humans. The 13 nation interphone project was the largest study of its kind and it did not find a solid link between mobile phones and brain tumors. Another study was done by the International Journal of Epidemiology. They concluded that there was no increased risk of getting glioma and meningioma which are the most common types of brain tumor by the use of mobile phones. There were suggestions that there could be more of a risk at higher exposure levels, but this was never tested. The effects of long term heavy use of mobile phones requires further investigations. The director of the International Agency for research on cancer, Dr Christopher wild said that there was no increased level of risk established from the data from the Interphone. Though he also said that at the highest level of call time and changing patterns of mobile phone use scince the study done by interphone, that further investigation of brain cancer risk and mobile phone use is merited. Professor Ian Olver said that the findings from the interphone study that was conducted across 13 countries were cosistant with othe reasearch that had been done. They had all failed to find a link between mobile phone use and cancer. This reasearch shows that mobile phones don’t damage DNA, which means that they can’t cause the types of genetic mutations that cause cancer. But it has been suggested that electromagnetic fields associated with mobile phones could possibly play a role in speeding up the development of an existing cancer. In 2004 a Danish study took place for over 10 years this study found no evidence to support a link. Though this study has been criticized for collecting data from subscriptions not necessarily from actual users. And that only 61% of a small sample of the subcribers reported use of mobile phones when they responded to the questionaire. A sweedish study done in 2005 has the same conclusion that the data they obtained does not ssupport the hypothesis that mobile phone use is related to an increased risk of cancer. Another study done in 2005 by the Brittish suggest that there is no risk of acoustic neuroma in the first 10 years after starting mobile phone use. But a risk any longer than that could not be ruled out. A 2006 German study also came up with the same conclusion that there was no overall risk of brain tumors glioma or meniglioma in the cellular phone users, and that there needs to be more results from long term cell phone use before they can draw conclusions. But there was one study done by a Sweedish scientific team in 2004 which suggested that regular fone use for 10 years or over was associated with an increased risk of acoustic neuroma a type of brain tumor. Age is a significant factor. The report done by the public health implications of wireless technologies report repeated the findings that the use of cell phones before the age of 20 increased the risk of brain tumors. The same repoert also concluded that current mobile phones are not safe for long term exposure. According to new research people that have regulary used their celphones for 10 years or longer are significantly more likely to develop a certain type of brain tumor on the side of there head where they hold there mobile phone. The International Journal of cancer is the second study that has suggested this, as the tumors also appear close to where the mobile phone emissions enter ther head. There have been many other studies that have found no connection between mobile phone use and cancer. Some of these studies were done on short term use (less than 10 years) which even this study had said but in the long term (more than 10 years) there were possible hints of increased cancer risks. But there is certainly need for a long term international study as these hints need further explanation. There is 39 % more risk of getting a glioma if you have used a mobile for 10 years or more. Another reason why this seems credible is because it make sense in terms of the length of time taken for tumors to develope. I have researched about 11 other studies done and all but a couple of those had concluded that there was no link between mobile phone use and cancer, but the someof these studies had been decided unrealiable, were short term studdies or they had other possible untested suggestions. One of the other tests I studied said that age is a significant factor and that use of mobile phones before the age of tweenty has an increased risk of developing brain tumors. This new report claims that the decade long Interphone study was so flawed that the risk levels it produced should be increased sigificantly. It also states that the worlds mobile phone users should keep handsets away from their heads and bodies to lower the risk of developing cancer. It also concludes that making calls for more than half an hour a day could increase the users risk of developing brain cancer by up to 40 %. A member of America’s Environmental Health Trust lobby group said that what has been discovered indicates that there will be a brain tumor pandemic if people aren’t warned or encouraged to change the amount and ways we use our cell phones. But even these researchers admitted that the end results were not conclusive, could have been effected by statistical errors or bias, which some believe means that the true risk of developing brain tumors for mobile phone users is at least 25% higher than thought origionally. But on the other hand there are still no good constistant explanations for how mobile phones could in fact cause cancer. Even the majority of studies done have concluded that there was no link between cancer and mobile phones, also the rates of cancer have not increased compared to the amount of sky rocketing use of mobile phones. After the adjustments of the Interphone study, it is still not significant statistically, or right on the borderline. This means there still needs to be more investigation into the subject or otherwise who will know who to believe? Bibliography [] [] [] \
