Heavy cell phone users who hold phones directly to their heads face 58% higher tumor risk on the same side they use their phone.

Plain English Summary

Summary written for general audiences

Israeli researchers studied 460 people with parotid gland tumors (located near the ear) and compared their cell phone use to 1,266 healthy controls. While overall cell phone use didn't increase tumor risk, heavy users who held phones directly to their heads showed a 58% higher risk of developing tumors on the same side where they used their phone. This suggests that intensive cell phone use without hands-free devices may increase risk of tumors in glands near where the phone is held.

Study Details

The objective of this nationwide study was to assess the association between cellular phone use and development of parotid gland tumors (PGTs).

The methods were based on the international INTERPHONE study that aimed to evaluate possible adverse...

For the entire group, no increased risk of PGTs was observed for ever having been a regular cellula...

Based on the largest number of benign PGT patients reported to date, our results suggest an association between cellular phone use and PGTs.
