Cell Phones and Brain Tumors: No Connection?
Study Finds 'No Observable Effect' of Cell Phone Usage on Brain Tumor Incidence
The American Cancer Society says that in looking at most studies as a whole, no link between cell phones and tumor development has been found.
Deltour and colleagues, who studied data on 59,984 men and women aged 20-79 diagnosed with brain tumors, say that if there is a linkage between the disease and cell phone use, the numbers don’t reveal it.
"Our finding that brain tumor incidence rates were either stable, decreased, or continued a gradual increase that started before the introduction of mobile phones is consistent with mobile phone use having no observable effect on brain tumor incidence…,” the authors conclude.
They add that population groups that are heavy mobile phone users should be studied for longer periods of time.
Michael Thun, MD, vice president emeritus, of the ACS, tells WebMD that “this is a good study” that “clearly shows the incidence” of brain tumors doesn’t increase after a period of five to 10 years.
However, he says more research needs to be done to see if longer-term use can cause tumors.
"That’s important, because it’s an incredibly widely-used technology,” he says. “The study doesn’t answer the question of what happens after 50 years.”
John Walls, a vice president of the mobile industry trade group, CTIA-The Wireless Association, says “peer-reviewed scientific evidence has overwhelmingly indicated that wireless devices do not pose a public health risk” and that the ACS, the NCI, the World Health Organization and the U.S. Food and Drug Administration “all have concurred that wireless devices are not a public health risk.”
