Cancer cells are found in the lobules or ducts. They have not moved to the lymph nodes or spread beyond the breast tissue.
In ductal carcinoma in situ, the cancerous cells are in the milk ducts. Most patients do not have symptoms. DCIS is often found during screening mammograms. Symptoms may include:
All women with DCIS are referred for treatment. Treatment may include surgery, radiation, and/or endocrine (hormonal) therapy. After you have DCIS, your risk for invasive breast cancer is 2.1-4 times greater.3

Paget's disease is a rare form of breast cancer. It involves the skin of your nipple and areola (dark skin around your nipple).
Symptoms include:
Paget's disease represents about 1-4 percent of breast cancer. It may be seen in women and men.6
Lobular carcinoma in situ (LCIS) is also referred to as lobular neoplasia. LCIS is not cancer. It is a risk factor (or marker) for invasive breast cancer. Women with LCIS have a higher risk for invasive breast cancer later in life. This risk is not limited to the breast where the LCIS was found; it can occur in either breast. Frequent monitoring and plans to reduce your risk are typically recommended for women with LCIS. Your doctor will discuss what treatment is best for you.
