A Swedish study on the use of wireless phones, including cell phones and cordless phones, has uncovered a link between electromagnetic radiation exposures and the risk of malignant and non-malignant brain tumors.
Cell phones and cordless phones emit a form of non-ionizing electromagnetic radiation, radiation which can be absorbed by tissues and cells that come into close contact with the phone, e.g., the head and neck. The most conclusive evidence as to the dangers of cell phone and similar radiation exposures come from studies on long-term exposure (ten years or more) like this Swedish study.
This new study reveals that people who used cell phones and cordless phones for more than a year were at a 70% greater risk of brain cancer compared to those who used cell phones and cordless phones for a year or less. Those who used cell phones and cordless phones for more than 25 years were found to have a 300% greater risk of brain cancer than those who used cell phones and cordless phones for a year or less.
The total number of hours of cell phone and cordless phone use was found to be as important as the number of years of use. A quarter of the study's subjects were found to have lifetime cell phone or cordless phone use of 2,376 or more hours, which corresponds to about 40 minutes a day over ten years. Heavier users were found to have a 250% greater risk of brain tumors compared to those who'd never used cell phones or cordless phones or used them for less than 39 hours in their lifetime.brain ] [ cancer ] [ cell-phones ]
