The connection between cell phones and cancer is controversial. Years of studies have generated results found. But there is no consensus on the degree of cancer risk posed by the use of cell phones. The main concern seems to be the development of brain tumours associated with the use of mobile phones. Some studies suggest a slight increase in the rate of brain tumors since the 1970s, but those subtle increases may be related to other factors such as greater access to the medical system and improvements in diagnostic imaging, as well as a slight increase in actual brain lymphomas due in part to HIV and other diseases that affect the immune system.
In fact, it would be impossible that cell phones are the cause of an increase in brain in 70 tumors because in those years they were not used. Then, what found on cell phones and cancer researchers? In a recent study that followed more than 420,000 users over a period of 20 years found no evidence that there is a connection between cell and brain tumor. Another recent study suggested an association between cell phone and cancer of the salivary glands. However, only a small number of participants had malignant tumors and had a clear increase in the use of tobacco known cause of cancer of the salivary glands between those participants. However, a series of recent studies can not tell the tale. Sometimes many years between the use of a new provocative agent of cancer such as tobacco and the observation of an increase in cancer rates. At this point, it is possible that too little time has passed to detect an increase in cancer rates directly attributable to the use of mobile phones.
In short? For now, nobody knows if cell phones are capable of causing cancer. Although long term studies are under way, to date there is no convincing evidence that may be a risk of cancer. For those who are concerned, the Council is limiting the use or using a handset that the antenna of the phone away from the body.
