Heavy users of mobile phones are 50 percent more likely
to develop cancer of the salivary glands, according to a new study
conducted by researchers at Tel Aviv University and published in the American Journal of Epidemiology.
studied 500 Israelis who had tumors of the salivary gland, and compared
their cell phone usage to 1300 Israelis who did not have such tumors.
They found that those who use cellular phones several hours per day
against the same side of the head had a 50 percent higher tumor risk
than those who used phones less frequently.
Rural residents with heavy mobile phone
use had an even higher tumor risk, compared with urban users. The
researchers speculated that this could be due to the higher radiation
dose needed for mobile phones to function in areas with fewer towers.
A number of studies have linked heavy mobile phone use the health problems such as sleep disruption and brain cancer.
While the mobile phone industry often says that studies have proved the
devices safe, the researchers noted that these studies tend to look
only a short-term exposure, whereas radiation-related health problems may often take up to a decade before symptoms develop.
researchers said that carrying out studies in Israel, where the level
of mobile phone use (and thus radiation exposure) is very high, can
give insight otherwise only available from a longer-term study.
to other studies, the amount of exposure to radiofrequency radiation we
saw here was much higher," said lead researcher Siegal Sadetzki. "If

The researchers also noted that many studies look only for brain tumors,
and not other health problems like the one examined in the current
study. This could be because cancer of the salivary gland is normally
quite rare, accounting, for example, for only 0.23 percent of all
cancers diagnosed in the United Kingdom each year.
