No Link Found Between Cell Phone Use and Cancer

FRIDAY, Oct. 21 (HealthDay News) -- In what may be the largest study to date evaluating cancer risk in cell phone subscribers, Danish researchers have found no evidence of increased central nervous system tumor rates in long-term holders of cell phone subscriptions; their findings have been published online Oct. 20 in BMJ.

Patrizia Frei, Ph.D., of the Danish Cancer Center in Copenhagen, and colleagues followed 358,403 Danish citizens with cell phone subscriptions between 1990 and 2007 to investigate the risk of tumors to the central nervous system in cell phone users.

The researchers found 10,729 central nervous system tumors in the population of cell phone subscribers; however, even when considering only those with the longest history of cell phone subscription (13 years or more), tumors occurred at a rate on par with tumor rates in non-cell phone subscription holders. Also, there seemed to be no correlation between the anatomical location of tumors and the position in which handsets are held.

"In this update of a large nationwide cohort study of mobile phone use, there were no increased risks of tumors of the central nervous system, providing little evidence for a causal association," the authors write.
