Lobular Carcinoma in Situ (LCIS)
While lobular carcinoma in situ (LCIS) sounds like a type of breast cancer, it is really a risk factor or marker for an increased risk of developing breast cancer.
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.
Many of our patients with LCIS benefit from a high-risk clinic program, The Johns Hopkins Breast and Ovarian Surveillance Service (BOSS). The program focuses on ways to reduce the risk of developing breast cancer and gives women tools to manage the knowledge that they are at higher risk. A medical oncologist who specializes in high risk assessment and evaluation can assess your overall risk and recommend ways to reduce risk in the future, such as hormonal therapy for breast cancer prevention.
