is it worse if chemo is needed for breast cancer
1 Breast cancer in premenopausal women tends to be more aggressive, so chemotherapy is often part of the treatment plan. 2  Chemotherapy may be recommended for some women diagnosed with early-stage breast cancer if the cancer is hormone-receptor-negative and HER2-positive.For more information on the specific characteristics of each cancer stage, visit the Breastcancer.org Stages of Breast Cancer page.). Chemotherapy is used after surgery to remove the breast cancer to get rid of any cancer cells that may be left behind and to reduce the risk of the cancer coming back.
