In a brief news report in the Baylor Innovations magazine (put out by Baylor University in Dallas), it was reported that:
"People who use cell phones for many hours a day are 50 per cent more
likely to develop mouth cancer than those who do not use a cell phone, according
to a study published in the American Journal of Epidemiology.
Researchers in Israel compared 500 people with benign and malignant tumors of
the salivary glands and 1,300 healthy people. People who used cell phones for
many hours a day were 50 per cen tmore likely to develop a tumor of the parotid
gland than infrequent users of cell phones. The parotid gland, the largest
salivary gland, is located near the jaw and ear where cell phones are typically
held. Other studies have been conducted that found no link between cell phone
use and increased cancer risk, but the researchers noted that Israelis adopted
cell phones quickly and are typically heavy users of the devices."
It has been a few years, but it seems to me that I heard of another report from a Swedish study that linked brain cancer to heavy cell phone usage. That country is another very high usage country.
I rarely even use my minutes each month... so I don't suppose I have high risk for it... but for you multiple-hour/day cellphone users... perhaps you should get one of those dorky blue-tooth things or go back to the old phone on the wall?
