This Danish study found no increased risk of acoustic neuroma brain tumors from cell phone use, even after 10+ years of regular use.

Plain English Summary

Summary written for general audiences

Danish researchers studied 106 people with acoustic neuroma (a non-cancerous brain tumor near the ear) and 212 healthy controls to see if cell phone use increased tumor risk. They found no increased risk of developing these tumors, even among people who used cell phones for 10 years or more. Importantly, tumors didn't occur more often on the side of the head where people typically held their phones.

Study Details

In this Danish study, the authors examined the possible association between use of cellular telephones and development of acoustic neuroma.

Between 2000 and 2002, they ascertained 106 incident cases and matched these persons with 212 random...

The overall estimated relative risk of acoustic neuroma was 0.90 (95% confidence interval: 0.51, 1.5...

The results of this prospective, population-based, nationwide study, which included a large number of long-term users of cellular telephones, do not support an association between cell phone use and risk of acoustic neuroma.

Quick Questions About This Study

A 2004 Danish study of 106 acoustic neuroma patients found no increased risk of these non-cancerous ear tumors from cell phone use. Even people who used phones for 10+ years showed no elevated risk compared to short-term users.
Research shows acoustic neuromas don't occur more frequently on the side where people typically hold their phones. A Danish study found no correlation between which ear people used and where tumors developed.
A population-based study found that using cell phones for 10 years or more did not increase acoustic neuroma risk compared to short-term users. The relative risk was actually slightly lower at 0.90.
Danish researchers found no correlation between acoustic neuroma tumor size and cell phone usage patterns. Heavy phone users didn't develop larger tumors than light users in this nationwide study of 106 patients.
A comprehensive Danish study comparing 106 acoustic neuroma patients with 212 healthy controls found no association between cell phone use and developing these ear tumors. The overall relative risk was 0.90, indicating no increased danger.
