Brain Cancer linked with Cell Phones?
A branch of the World Health Organization, The International Agency for Research on Cancer has officially linked cellphone usage with being "possibly carcinogenic." It only points out the "possibility" of a link and the need for caution when using cellular devices.
Cell phones emit radio waves during phone calls and other data transmissions, and this is a form of electromagnetic radiation. It is not clear how large quantities of these waves affect our biological tissues, but some scientists believe that these waves may spur the growth of brain tumors.
Studies have shown there there is a spike in glioma tumor rates among people with the highest level of cellphone usage--those who talk for at least a half hour per day for a decade. There has not been a correlation for less frequent users.
You can best minimize your radiation exposure by using a headset/bluetooth device, which allows you to use your cellphone without holding the phone to your ear. The power radiated from the phone drops enormously with distance, and some scientists even say that you can decrease your exposure by holding your phone and inch or two away from your ear during phone calls.
Buy a headset...It's better to be safe than sorry!
