Your inverted nipples are almost certainly not a symptom of breast cancer. Worry over this appears to have begun with a line in the Wikipedia article on inverted nipples that misleadingly stated (based on another on-line source) that inverted nipples are a sign of breast cancer. Both the Wikipedia article and the other source have since been changed to remove the misleading information. The National Cancer Institute has a FAQ that points out that a sudden change in nipples (e.g. from everted to inverted) can be a sign of breast cancer (or several other, less concerning conditions), but nipples that have always been inverted are not a sign.While breast cancer can happen in men, it is extremely rare, with a lifetime risk of 0.1% (compared with 12% in women). More information about breast cancer in men is available from the American Cancer Society.
