Cell phone cancer risk depends on study

October 14, 2009 An analysis of 23 studies found no connection between mobile phone use and head and neck tumors.

However, when eight of the most scientific studies were reanalyzed, cell phone users were shown to have a 10 to 30 percent increase risk of tumors.

On their own, researchers say these studies are not enough to prove a clear link.

The main message of the analysis in the Journal of Clinical Oncology is that studies on cell phones need to be more scientific to be taken seriously.
