Breast cancer rates may be higher among some autoworkers, but it is not always clear why. This project will investigate how workplace exposures in the auto industry may be linked to breast cancer risk by collecting information from workers and analyzing health data from autoworkers across Ontario. The goal is to identify factors that may increase risk and support safer workplaces.

The results will provide important evidence to support workplace health policies, prevention efforts, and better protection for workers who may
be at increased risk of breast cancer.
