Ductal Carcinoma in Situ (DCIS) and Lobular Carcinoma in Situ (LCIS): Comprehensive Care by Dr. Lindsay Keith

Dr. Lindsay Keith


Ductal Carcinoma in Situ (DCIS) and Lobular Carcinoma in Situ (LCIS) are both non-invasive types of breast cancer. As an experienced breast surgeon, Dr. Lindsay Keith offers expert diagnosis and treatment for these conditions.

About Ductal Carcinoma in Situ and Lobular Carcinoma in Situ

Both DCIS and LCIS are non-invasive forms of breast cancer, meaning they remain confined to the place they originated. DCIS originates in the milk ducts, while LCIS originates in the milk-producing glands. Although both are considered non-invasive, they may increase the risk of invasive breast cancer in the future.


These conditions are often diagnosed through mammogram screenings. If an abnormal area is detected, a biopsy is usually recommended to confirm the diagnosis.

Treatment Options

Treatment for DCIS and LCIS can vary, with options ranging from surgery to remove the abnormal cells, radiation therapy, hormone therapy, or a combination of these. In some cases, especially for LCIS, careful monitoring may be recommended instead of immediate treatment.
