There is no such thing as stage 1 grade 3 triple-negative breast cancer. Triple-negative breast cancer can be categorized into four stages, including stage Ⅰ, stage Ⅱ, stage Ⅲ and stage Ⅳ. Among them, stage I is divided into stage IA and stage IB. If a patient with triple-negative breast cancer is in stage Ⅰ, it means that it is in the early stage of the disease. At this time, if the patient follows the doctor’s instruction to undergo surgery as soon as possible, the prognosis is better, and the disease may even be cured. When breast cancer patients are in early stage, the cancer cells have not spread and the lesions are still limited, so if they follow the doctor’s advice to have breast preservation surgery or total mastectomy, there is a certain chance that the disease can be cured. At this time, there is a certain chance that the disease can be cured, so it is suggested that patients should be detected and treated early. If the disease develops to stage II, the lesion becomes bigger or the cancer cells have metastasized to the lymph nodes, the disease can be cured through combined treatment such as surgical excision of the lesion and axillary lymph node dissection surgery. If the disease develops to stage III, surgery is also possible, and there is a possibility of cure. If the disease develops to stage IV, there is basically no possibility of cure, and the patient’s life can only be prolonged by means of chemotherapy and radiotherapy, etc. Therefore, it is recommended that patients with triple-negative breast cancer should be treated with chemotherapy and radiotherapy. Therefore, it is recommended that patients with triple-negative breast cancer should be detected and treated as early as possible.
