Israeli researchers say they've found a link between cell phones and cancer.
A study led by Dr. Siegal Sadetzki, an oncologist at the Chaim Sheba Medical Center in Ramat Gan, Israel, found a nearly 50 percent increase in the risk of tumors of the parotid gland, a salivary gland found slightly ahead of each ear.
Agence France-Presse quoted a report in the Israeli newspaper Yediot Aharonot, which apparently said the risk was highest those who used their cell phones for more than 22 hours per month, held the phone to the same ear or lived in rural areas.
AFP said it saw an abstract from the American Journal of Epidemiology, where the study is to be published.
Dozens of studies regarding cell phones and cancer have been carried out over the past 15 years, with often contradictory results.
