What is lobular carcinoma in situ (LCIS) type of breast cancer?

ANSWER

Lobular carcinoma in situ (LCIS) is when abnormal cells appear in the lobes of the breast, but nowhere else. You may not feel a tumor, and there may not be any changes in your mammogram. It’s often found during a breast biopsy for something else. Women with LCIS need to see a doctor often for checkups and to discuss if any treatment is needed. LCIS increases the risk of developing a cancer in either breast that can spread.
