Abstract

Overview

Using data from the Swedish Inpatient Register, this study analyzes brain tumor rates (unknown type, D43) across various age groups between 1998 and 2015. This extensive review aims to shed light on trends and demographic dependencies in brain tumor incidences potentially linked to mobile and cordless phone usage.

Findings

• General Trend: The Average Annual Percentage Change (AAPC) of brain tumors per 100,000 population showed an increase of +2.06% (95% confidence interval: +1.27, +2.86%) across both genders.
• Notable Shift: A significant joinpoint detected in 2007 divides the trend into two periods: 1998-2007 with an APC of +0.16% and 2007-2015 with an APC of +4.24%.
• Age-Specific Observation: The highest AAPC was recorded in the 20-39 years age group, demonstrating an increased vulnerability or susceptibility in younger adults.
• Cytology and Imaging: Over the years, there was an increase in the diagnosis of brain tumors based on imaging techniques such as CT and MRI, leading to potential underreporting in established cancer registries.

Conclusion

This analysis suggests an underestimation of actual brain tumor cases, raising concerns about the reliability of cancer register data. Additionally, the connection between rising brain tumor rates and the use of wireless phones should be a significant focal point of public health discussions and further research.
