Cell phones don't raise cancer risk: study
(Reuters)Updated: 2006-12-07 17:06
A total of 14,249 cancer cases were seen among the cellular telephone users, a number that was lower than would be expected for that population, according to the study appearing in the Journal of the National Cancer Institute.
CLEAN BILL OF HEALTH
"We were not able to identify any increased risks of any cancers that could be related to the use of the cellular phones," John Boice, a cancer epidemiologist at Vanderbilt University who worked on the research, said in an interview.
Boice said the type of radiation involved in cell phones is not known to damage cells or DNA. "So there's no biological mechanism that would suggest that even this type of exposure could cause cancer or DNA damage," Boice said.
The study reinforces the consensus among leading health organizations that cellular phones do not cause harmful health effects, a wireless industry group said.
"The overwhelming majority of studies that have been published in scientific journals around the globe show that wireless phones do not pose a health risk," said Joseph Farren, spokesman for CTIA, the Washington-based wireless industry group.
The researchers acknowledged some limitations in their work. Schuz said they could not differentiate between people who used the phones frequently and those who did so sparingly, meaning the researchers could not rule out the possibility that some type of increased risk exists among heavy users.
"There is, in fact, a hazard from the use of a cellular phone that we have to all be concerned about," added Boice, but it is not cancer-related. "And that's using a phone when we're driving an automobile," leaving a driver distracted and causing accidents.
The study was funded by the Danish Cancer Society and Danish Strategic Research Council.
