Breast cancer in older women continues to be a clinical problem and therapeutic challenge. The clinical presentation, biological characteristics and survival rates are comparable between older and younger women with breast cancer. Treatment of breast cancer in older women should aim to ensure satisfactory control of locoregional disease and prolongation of survival, for as long a period as possible. Optimal surgical therapy should be as for younger patients and adjuvant therapies may be required (considering side-effects and benefits). However, randomized trials are required to clarify the role of adjuvant treatments in older patients.
