Occupational exposure to magnetic fields and breast cancer among Canadian men.

Occupational magnetic field (MF) exposure has been suggested as a risk factor for breast cancer in both men and women. Due to the rarity of this disease in men, most epidemiologic studies investigating this relationship have been limited by small sample sizes. Herein, associations of several measures of occupational MF exposure with breast cancer in men were investigated using data from the population-based case-control component of the Canadian National Enhanced Cancer Surveillance System.

Brain cancer and occupational exposure to magnetic fields among men: results from a Canadian population-based case-control study.

Background: The relationship between occupational exposure to magnetic fields and brain cancer in men was investigated using population-based case-control data collected in eight Canadian provinces. Emphasis was placed on examining the variations in risk across different histological types.

Methods: A list of occupations was compiled for 543 cases and 543 controls that were individually matched by age.
