Cases with tinnitus after using analogue cellular telephones are presented. An increased odds ratio of 3.45, 95% confidence interval (CI) 1.77–6.76, was found for vestibular schwannoma (VS) associated with the use of analogue cell phones. During the time period 1960–1998, the age-standardized incidence of VS in Sweden significantly increased yearly by +2.53% (CI 1.71–3.35). A significant increase in the incidence of VS was only found for the latter of the two time periods 1960–1979 and 1980–1998. For all other brain tumors taken together, the incidence significantly increased yearly by +0.80% (CI 0.59–1.02) for the time period 1960–1998, although the increase was only significant for benign tumors other than VS during 1960–1979.
