Treatment of Breast Cancer by StageStaging is the process of finding out how far the cancer has spread. Your treatment and the outlook for your recovery depend on the stage of your cancer. Treatment choices for breast cancer depend not only on the stage of the disease, but also on other factors, such as your health and personal preferences.In general, the lower the number, the less the cancer has spread. A higher number, such as stage IV (4), means a more serious cancer. Stage 0: There are two types of stage 0 cancer, ductal carcinoma in situ (DCIS) and lobular carcinoma in situ (LCIS). Most women with LCIS do not need treatment but close follow-up is important. This condition increases the risk of later developing cancer in either breast. Treatment for DCIS includes:
Stage I: One option is lumpectomy with removal of lymph nodes under the arm followed by radiation therapy. Another option is modified radical mastectomy. Additional therapy may follow the surgery depending on the size and other features of the tumour. Stage II: Surgery and radiation therapy options for stage I and stage II tumours are similar, except that in stage II, radiation therapy may be considered after mastectomy if the tumour is large or has spread to many lymph nodes. Adjuvant therapy may include chemotherapy, hormone therapy or both. Stage III: Some combination of surgery (lumpectomy or a modified radical mastectomy), chemotherapy, radiation and hormone therapy is often used. Sometimes chemotherapy (with or without hormonal therapy) is given both before and after the surgery. Stage IV: Systemic therapy is the primary treatment, using chemotherapy, hormonal therapy or both. Radiation and/or surgery may also be used to provide relief of certain symptoms.
