Residential exposure to overhead high-voltage lines and the risk of testicular cancer: results of a population-based case-control study in Hamburg (Germany) epidem.

Aim of study (acc. to author)

This population-based case-control study was conducted in Germany to investigate the association between residential exposure to overhead high-voltage lines and testicular cancer.

Further details

Exposure to overhead high-voltage lines was defined by distance and residence time in days. In model A (ever versus never exposed), a man was classified as exposed if he had ever lived within a corridor of 100 m from a overhead high-voltage line. In model B, residence time and the inverse distance from the nearest overhead high-voltage line within a corridor of 250 m were taken into account.

Results (acc. to author)

The data showed no substantial association between residential exposure to high-voltage lines and the risk of testicular cancer. However, the risk for younger men below the age of 40 years was slightly increased.
