How is ductal carcinoma in situ treated?

ANSWER

Most women with ductal carcinoma in situ (DCIS) don't have the breast removed with a mastectomy. Instead, they have breast-conserving surgery.

Most common is a lumpectomy followed by radiation. In a lumpectomy, the surgeon removes the cancer and a small area of healthy tissue around it. The tissue is taken to make sure all the cancer cells have been removed. Lymph nodes under the arm don’t need to be removed as they are with other types of breast cancer.
