Stages of breast cancer range from stage 0 to stage IV, with stage 0 being localized to the breast with no spreading. In stage IV, the tumor has spread to other organs. For stage 0, the five-year survival rate is about 100%. Treatment for stage 0 breast cancer may include surgery, radiation, or hormone therapy. In other stages, recommended treatment may include surgery along with radiation, chemotherapy, hormone therapy, and sometimes biological therapy. Some women may choose a clinical trial for treatment.
