The World Health Organization is saying radiation from cell phones can indeed cause Cancer.

According to CNET, the International Agency for Research on Cancer (IARC), which is an arm of the WHO, said it now lists mobile phone use in the same category as lead, gasoline engine exhaust, and chloroform. Officially, cell phone radiation is listed as a "carcinogenic hazard."

Experts interpreting the findings are suggesting that those who use a mobile phone for about an hour each day, over a ten-year period may be at an increased risk of developing certain types of brain tumors.

The FCC, Food and Drug Administration, and the wireless industry have always maintained that cell phones are safe.

It should be pointed out that the World Health Organization's finding were not based on any new studies, but an extensive review of previously published reports. A team of 31 scientists from 14 countries, including the US, said it had found enough evidence to consider radiation from mobile phones to be "possibly carcinogenic to humans."

In the past, medical experts have encouraged those that are heavy cell phone users to use headset devices, in order to minimize the amount of time a handset is pressed to the side of the head.  Want to read more about the ongoing research into cell phone safety?  CNET is publishing a three-part report, with in-depth examination of the scientific evidence.  Part one can be found here.
