Worldwide, breast cancer is the most common type of non-skin cancer in women. The approach to evaluation of breast cancer is known as the triple assessment, consisting of a clinical examination, imaging studies and needle biopsy.Breast cancer surgery aims at conserving the breast and performing a sentinel lymph node biopsy in the axilla.Breast-conserving surgery is followed by postoperative radiotherapy. Adjuvant drug treatment may consist of either chemotherapy or endocrine therapy or both. The follow-up of a patient after breast cancer consists principally of a physical examination and mammography every 1–2 years .
