This study found no increased risk of parotid gland tumors from mobile phone use, even after 10+ years of exposure.

Plain English Summary

Summary written for general audiences

Researchers in Denmark and Sweden studied whether long-term mobile phone use increases the risk of parotid gland tumors (tumors in the salivary glands near your ears). They compared 172 people with these tumors to 681 healthy controls, examining their mobile phone usage patterns over more than 10 years. The study found no increased risk of either malignant or benign parotid gland tumors associated with mobile phone use, even among long-term users.

Study Details

Handheld mobile phones were introduced in Denmark and Sweden during the late 1980s. This makes the Danish and Swedish populations suitable for a study aimed at testing the hypothesis that long-term mobile phone use increases the risk of parotid gland tumors.

In this population-based case-control study, the authors identified all cases aged 20-69 years diagn...

For regular mobile phone use, regardless of duration, the risk estimates for malignant and benign tu...

The authors conclude that the data do not support the hypothesis that mobile phone use is related to an increased risk of parotid gland tumors.
