Long-term cell phone users (10+ years) showed 25% higher brain tumor risk, highlighting concerns about cumulative EMF exposure over time.

Plain English Summary

Summary written for general audiences

Researchers analyzed nine case-control studies involving over 17,000 people to examine whether cell phone use increases brain tumor risk. They found no overall increased risk for typical users, but discovered a 25% higher risk among people who used cell phones for 10 years or longer. This suggests that while short-term use appears relatively safe, long-term exposure may pose health concerns that require further investigation.

Study Details

We conducted a meta-analysis to examine the effect of cellular phone use on the risk of brain tumor development.

We searched the literature using MEDLINE to locate case-control studies on cellular phone use and br...

We found no overall increased risk of brain tumors among cellular phone users. The potential elevated risk of brain tumors after long-term cellular phone use awaits confirmation by future studies.
