Stage 0 Breast Cancer
A stage 0 breast cancer diagnosis, also known non-invasive cancer or ductal carcinoma in situ (DCIS), signifies that abnormal cells are present in the breast milk duct lining. DCIS is the earliest form of breast cancer, representing about one in every five breast cancer diagnoses, and typically responds well to treatment since the cancerous cells have not spread to other tissues in the body.
