what is stage 3 breast cancer

Stage 3 breast cancer is an advanced stage of breast cancer where the cancer has extended beyond the immediate region of the tumor and may have invaded nearby lymph nodes and muscles. It is divided into three subcategories: 3A, 3B, and 3C. The specific characteristics of each subcategory vary, such as the size of the tumor and the extent of lymph node involvement. Treatment for stage 3 breast cancer typically involves a combination of surgery, chemotherapy, radiation therapy, and targeted therapies, and the specific treatment plan is determined based on individual factors and the stage at which the cancer is diagnosed
