Possible Cellphone-Cancer Link Found in Rats: US Government Study

U.S. National Toxicology Program has released the early findings

A partial report from a U.S. government study on on rats and mice has found a possible link between cellphones and cancer, giving new life to the longstanding debate over whether cellphone use might lead to cancer, NBC News reported.

The report is not finished yet, but advocates pushing for more research learned of the partial findings and the U.S. National Toxicology Program has released them early.

The partial findings suggest that male rats exposed to constant, heavy doses of certain types of cellphone radiation develop brain and heart tumors. But female rats didn't, and even the rats that developed tumors lived longer than rats not exposed to the radiation.

Dr. Michael Lauer of the NIH said there's just not enough information to say whether the experiment shows the radiation caused the tumors. 

The National Toxicology Program, part of the National Institutes of Health, is still analyzing the findings. 

What they do not show is whether humans are at any risk from using cellphones, or whether using a headset or keeping phones away from the head and body might make a difference.
