After reading this title, I imagine how many people of our generation do not fall into this category. In today's world it is difficult to go anywhere without seeing someone talking on a cell phone. Even if you walk, drive or play on the streets, you will be able to see them everywhere. Whether or not someone answering their cell phone increases the chance of fatal brain cancer is up for debate. Apparently a lot of research has been completed in recent years looking for a solid answer to the question. Essentially, people are worried that their brain will be microwaved, breaking bonds and causing genetic damage and consequently the evolution of a cancerous tumor. For example, the New York Times magazine article describing the situation of a young man from Florida, David Reynard, on the same topic. He accepted the question of whether cellphones could cause links to the brain tumor that killed his wife. While the results of these studies are conflicting, puzzling, and offer nothing conclusive, a summary of previous studies investigating cell phone use was researched. Furthermore, the main reason for the uncertainty is due to the dependence on memory, the study of the subject's memory of how much he used the cell phone. The recall itself was the result of studies that ended up being considered unreliable. In fact, there were two conclusive findings; The first was that brain cancer is rare, and second, the control group for a study investigating cell phone use would be extremely difficult. Mr. Reynard then introduces how cell phone radiation differs from each other causing DNA to mutate; which can lead to cancer and other health problems. While there is a lot of controversy surrounding cell phones, I believe that if... middle of paper... experiment, rats were treated with a carcinogenic chemical in utero (to "cause" them to develop brain tumors) and then exposed at radiant energy comparable to cell phone radiation for two hours a day, four days a week, for 22 months. The experiment did not reveal an increase in the incidence of brain tumors in rats. Nor was any accelerated growth found in previously established brain tumors. From 1997 to 2004, six independent experiments in mice and rats studied the effects of chronic radiation on brain cancer. No experiments revealed an increased risk of brain cancer. But radiant energy does not need to penetrate the brain and mutate genes to have a biological effect on it. A cell phone user may experience changes in physiology that have nothing to do with the ionizing ability of radiation. Could a cell phone leave a physiological mark on the brain through a yet unknown mechanism??
