A breast tumor that remains in its site of origin is noninvasive breast cancer. This type of breast cancer can start in the milk ducts (ductal carcinoma) or the breast lobules (lobular carcinoma). Other names for noninvasive breast cancer are stage 0 breast cancer and carcinoma in situ, or carcinoma in place.

Carcinoma in situ rarely causes symptoms for both ductal carcinoma and lobular carcinoma. A very small amount of women with noninvasive ductal carcinoma may feel a lump or have breast discharge, but this is rare.
Noninvasive lobular cancer may not show up on a mammogram and often goes undiagnosed. If you do experience symptoms of breast cancer, tell your doctor at Dignity Health North State as soon as possible.
Treatment is slightly different for stage 0 ductal and lobular carcinoma. Since stage 0 breast cancer is confined to the site of origin, your doctor may recommend surgery to remove the tumor. For noninvasive ductal carcinoma, radiation therapy may follow the surgery to remove any remaining cancer cells.
Noninvasive lobular cancer is a precancerous condition, so your doctor may not recommend standard cancer treatment. However, because it is a warning sign of invasive cancer, your doctor will closely monitor the tumor and recommend hormone therapy or surgery to reduce the risk of the cancer advancing.
Trust our experienced doctors at Dignity Health North State to care for your type of noninvasive breast cancer, including making informed treatment decisions.
