itu). These terms can be unclear because LCIS isn’t cancer but DCIS is.

LCIS is an abnormal growth of cells within the breast parts that make breast milk.

DCIS is breast cancer that hasn’t grown outside of the milk ducts in the breast.

Does LCIS need to be treated?

The tumor will be removed and tests will be done to confirm there’s no cancer.

If you are likely to have breast cancer in the future, you may want to reduce your chances

by 1) making changes in your lifestyle, 2) taking treatment that stops cancer growth caused

by hormones (endocrine therapy), or 3) if at high-risk, have your breasts removed.

Breast exams by your doctor and yourself as well as pictures of the insides of your breasts,

called mammograms, are advised so as to find any cancer early.
