Abstract

BACKGROUND/AIM:

The main objective of this study was to evaluate if there was an increased incidence of brain tumours between years 1980-2012, a time period when mobile phone usage has increased substantially.

MATERIALS AND METHODS:

From the Swedish Cancer Registry, cases of meningiomas, low-grade gliomas (LGG) and high-grade gliomas (HGG) were identified in patients between 1980-2012. Direct age-standardised incidence rates were used to calculate incidence trends over time.

RESULTS:

A total of 13,441 cases of meningiomas, 12,259 cases of high-grade gliomas and 4,555 cases of LGG were reported to the register during the study period. The results suggest that there may be a negative development in the trend for LGG of -0,016 cases per 100,000 and year, corresponding to a mean reduction of approximately 1% per year.

CONCLUSION:

The present study was not able to demonstrate an increased incidence of glioma during the past 30 years in Sweden.
