Lobular Carcinoma in Situ (LCIS)
Lobular carcinoma in situ is an abnormal growth of the cells that line the part of the milk gland that actually makes milk after childbirth. Although the word “carcinoma” occurs in the name, it is not a breast cancer, but rather an abnormal growth pattern that is associated with increased breast cancer risk in the future.
What can I do if I have LCIS cells in my breast?
First, there is no need to panic. LCIS simply means that we have identified that you may be at higher risk for developing breast cancer. The most important thing to do now is find a comprehensive breast center where your breast health can be closely monitored and managed.
Many women with LCIS opt for enhanced surveillance which includes a breast exam every six months while alternating mammograms with breast MRI. This increases the chance that if a breast cancer develops it will be diagnosed early when it is easier to treat. Another option is chemoprevention with anti-estrogen medications. This reduces the breast cancer risk by more than 50%. These options are provided in the Johns Hopkins Breast Center.
