Breast cancer is second only to
lung cancer as a cause of cancer death in women. It occurs when, for unknown reasons, cells become abnormal and divide without control or order. Breast cancer is a complex disease, and all cases are not the same.
Once the disease has been found and the diagnosis confirmed, more tests will be done to find out information on the specific pattern. This important step is called staging, and knowing the exact stage will help your healthcare provider plan your treatment.
- Stage 0 (including lobular carcinoma in situ and ductal carcinoma in situ)
- Stage I
- Stage II (including IIA and IIB)
- Stage III (including IIIA, IIIB, and IIIC)
- Stage IV
- Recurrent.
