With all the news about the World Health Org. stating that cell phones are probable human carcinogens, does anyone have any concerns in that regard about cochlear implants? Apparently, CI's emit the same type of radiofrequency radiation as cell phones. The WHO report says that cell phone users who use their phones for 1 or 2 hours a day for 10 yrs are at double the usual risk for brain cancer - what about CI implantees who are permanently implanted? Does anyone have any scientific proof that CI's do NOT cause or promote cancer?? Has any study ever been done on this?
