Singer Sheryl Crow says she believes her benign brain tumor was caused by frequent cellphone use, but the science to date does not support her theory.
Crow said that although no doctors will confirm it, she thinks it's possible her brain tumor, called a meningioma, is related to her cellphone use. "I [used to spend] hours on the old, archaic cellphones," Crow said on Monday's episode of Katie Couric's daytime talk show "Katie."
However, there is little evidence linking cellphone use to brain tumors, and most studies have not found a link. For one thing, brain tumors aren't any more common, although cellphone use has exploded.
"There is no conclusive proof that cellphones cause brain tumors," said Dr. Michael Schulder, vice chairman of the department of neurosurgery at Cushing Neuroscience Institute in Manhasset, N.Y.
About 6,000 people are diagnosed with meningiomas yearly in the U.S., according to the National Cancer Institute. Schulder told MyHealthNewsDaily that Crow falls into the group that is most prone to developing meningiomas — women in their 40s and 50s.
Although they're called brain tumors, meningiomas actually form in the lining of the brain rather than the brain itself. Most are benign, meaning they are unlikely to spread to other sites within the body.
"There is no reason to think that there's some other extra cause" for Crow's meningioma. "She meets the risk factor profile for developing that tumor," said Schulder, who is not involved in Crow's care.
