Long-Term Mobile Phone Use and the Risk of Vestibular Schwannoma: A Danish Nationwide Cohort Study Full Text
American Journal of Epidemiology, 07/25/2011
Schuz J et al. – No evidence was found that mobile phone use is related to the risk of vestibular schwannoma. Because of the usually slow growth of vestibular schwannoma and possible diagnostic delay, further surveillance is indicated.
Methods- The authors used 2 Danish nationwide cohort studies
- a study of all adult Danes subscribing for a mobile phone in 1995 or earlier
- a study on sociodemographic factors and cancer risk
- Authors followed subjects included in both cohorts for occurrence of vestibular schwannoma up to 2006 inclusively
- 2.9 million subjects
- A long–term mobile phone subscription of 11 years was not related to an increased vestibular schwannoma risk in men (relative risk estimate = 0.87, 95% confidence interval: 0.52, 1.46), and no vestibular schwannoma cases among long–term subscribers occurred in women versus 1.6 expected
- Vestibular schwannomas did not occur more often on the right side of the head, although the majority of Danes reported holding their mobile phone to the right ear
- Vestibular schwannomas in long–term male subscribers were not of larger size than expected
