Description

also called LCIS. Although not a true cancer, it is sometimes listed as a non-invasive type of breast cancer. It starts within the milk-producing glands (lobules) of the breast but does not grow through the wall of the lobules. It does not become an invasive cancer very often, but having LCIS places a woman at somewhat higher risk of developing an invasive breast cancer later in life. Women need a yearly mammogram and clinical breast exam after LCIS. Women with LCIS might also want to ask their doctors about the benefits and limits of yearly screening with magnetic resonance imaging (MRI). See also clinical breast examination, invasive lobular carcinoma, magnetic resonance imaging (MRI), mammogram.
