What are the goals in treating breast cancer in situ?

Cure! Breast cancer in situ, also known as DCIS, is the earliest form of breast cancer. It is cancer that is sitting quietly within the breast ducts.  It is not able to spread anywhere else inside the breast.  

Treatment is surgical.  A patient can have a mastectomy (removal of the breast) or a lumpectomy (removal of the area of cancer.)  After a lumpectomy, radiation is necessary in most cases.  

After a mastectomy for DCIS, 99% of women are completely cured!  The cure rate is also very high after a lumpectomy and radiation, but since there is breast tissue left, there is a slightly higher chance of having a breast cancer in the future.

With invasive breast cancer doctors consider several factors to guide treatment decisions: family history, disease-free margin measurements, molecular characteristics, tumor grade, number of lymph nodes affected, cell surface receptor status, genetics and tumor size.
