Who is affected by ductal carcinoma in situ (DCIS)?

Most women who get DCIS do not have a family history of breast cancer. Only about 5-10% of breast cancer cases are related to a genetic mutation or family history. Red flags for this include having a family history of breast cancer, especially if the cancer was discovered at a younger age, or before 50 years old. Other red flags for breast cancer that may be related to a genetic mutation include a family history of ovarian cancer, male breast cancer, multiple other cancers in the family and Ashkenazi Jewish ancestry. The most common risk factors for breast cancer include being female and getting older, and these are risk factors that cannot be changed.

Because the tissue in men’s breasts do not fully develop the way that the tissue in women’s breasts do, men do not usually get breast cancer of this type.
