What are the typical treatments for lobular carcinoma in situ breast cancer?

ANSWER

Treatments for lobular carcinoma in situ (LCIS) are:

Talk with your doctor about what’s right for you.

  • Hormone therapy to lower the risk of developing invasive cancer.
  • Double mastectomy. Surgery is sometimes performed to remove tissue in the area of the LCIS. Some women at high risk for breast cancer choose to have a double mastectomy, the removal of both breasts, because they’re worried about getting an invasive cancer. They might have a strong family history of breast cancer, or they might have genetic mutations called BRCA1 or BRCA2. After surgery, some women choose to have breast reconstruction surgery.
