MIAMI BEACH – Growing evidence continues to point to a widening separation between female and male breast cancers, particularly with discoveries suggesting different pathways to disease and important genetic distinctions.
Therefore, the traditional practice of extrapolating findings from female breast cancer research to men with breast cancer no longer makes sense, Patrick I. Borgen, MD, said at the annual Miami Breast Cancer Conference, held by Physicians’ Education Resource.
The incidence of male breast cancer is increasing. At the same time, fewer men with breast cancer get referred for and undergo genetic testing for their disease, said Dr. Borgen, chair of the department of surgery at Maimonides Medical Center in Brooklyn, N.Y.
Dr. Borgen explained in a video interview that both maternal and paternal inheritance of breast cancer are important, and they tie the lineage into a hypothesis for why BRCA mutations – which can predispose people to worse survival – have persisted through generations.
