EDISON - Heavy cell phone users worried that they might be setting themselves up for cancer can breathe easier.

The biggest study to look for any connection has found no link. It followed more than 350,000 people for about a decade and found that heavy cell phone users have about the same cancer rates as people who don't use cell phones.

The study, out of Denmark, confirms the findings of a smaller one reported on last year. It also confirms the assessments of the U.S. Food and Drug Administration and the Federal Communications Commission.

An advocacy group called MobileWise criticized the new study saying it wasn't long enough to consider the long-term risk of cell phones, since brain tumors can take decades to develop.
