A comprehensive Finnish registry study involving 31,687 breast cancer patients and 158,433 controls found no increased breast cancer risk linked to induced abortion or miscarriage. Researchers utilized national registries, adjusting for socioeconomic factors and hormone therapy usage. The study revealed no significant variation in breast cancer risk associated with the number of abortions or the age at first abortion. Despite some subgroup findings suggesting slight risk variations, overall results counter existing public myths, providing reassurance for clinical counseling.
