NETANYA, Israel Siegal Sadetzki, a physician, epidemiologist and lecturer at Tel Aviv University, has published a study of heavy users of cell phones and their likelihood of getting a particular form of cancer.
Sadetzki, published the results of the study in the American Journal of Epidemiology, in which she and her colleagues found that heavy cell phone users were subject to a higher risk of benign and malignant tumors of the salivary gland.
According the findings, there is an increased risk of about 50 percent for developing a tumor of the main salivary gland (parotid) on the side where subjects hold the cell phone, compared to those who did not use cell phones.
The study was done on an Israeli population. "Unlike people in other countries, Israelis were quick to adopt cell phone technology and have continued to be exceptionally heavy users. Therefore, the amount of exposure to radio frequency radiation found in this study has been higher than in previous cell phone studies," said Sadetzki.
"This unique population has given us an indication that cell phone use is associated with cancer," added Sadetzki, whose study investigated nearly 500 people who had been diagnosed with benign and malignant tumors of the salivary gland.
Subjects were asked to detail their cell phone use patterns in terms of the frequency and length of calls. They were compared to a sample of about 1,300 healthy control subjects.
