An Israeli doctor participating in an international study, has found a link between cellular phone use and cancer, and recommends that cell phone use be limited among children.

The study was conducted in 16 countries, with Israel's Dr. Sigal Sadetzki, director of the Gertner Institute of Epidemiology and Health Policy Research at Sheba Medical Center concluding that standards should be reassessed and tightened to prevent radiation from cell phones.  She said that current cell phone regulations do not relate to cancer caused by radiation, but rather to health risks posed by heat.

The study, published Friday in the American Journal of Epidemiology, found a clear link between cell phone use and cancerous growth in the saliva glands. Researchers found that among groups who tend to hold the phone on one side and use the phone frequently or for prolonged periods, the risk of saliva-glad cancer increased by 50 to 58 percent, compared to people who did not use a cell phone regularly. A number of studies in recent years indicate an increased cancer risk in the auditory nerve, the brain and the saliva glands for long-time cell-phone users.
