Breast pain (mastalgia) is a common cause of anxiety among women and frequently leads to a primary care clinic for consultation. Fortunately, mild premenstrual breast discomfort lasting for 1 to 4 days can be considered "normal." However, moderate-to-severe breast pain lasting over 5 days can interfere with usual activities, lead to unnecessary medical tests, and potentially invite the use of ineffective, occasionally harmful medications. Despite the severity of some patients' symptoms, mastalgia is still considered a trivial complaint by many physicians; often it is felt to be psychological in nature. Careful evaluation to rule out breast cancer and reassure the patient is enough to make the pain resolve in most cases. In a few patients, however, mastalgia is severe enough to deserve further evaluation and treatment. Overall, 92% of patients with cyclical mastalgia (CM) and 64% with noncyclical mastalgia (NCM) can obtain relief of their pain with the judicious use of several available therapies.

Flutamide at 125 mg daily during 12 months was the minimum effective dose to diminish hirsutism in patients with polycystic ovary syndrome or with idiopathic hirsutism.

Surgeons have routinely removed ipsilateral axillary lymph nodes from women with breast cancer for over 100 years. The procedure provides important staging information, enhances regional control of the malignancy and may improve survival. As screening of breast cancer has increased, the mean size of newly diagnosed primary invasive breast cancers has steadily decreased and so has the number of women with lymph node metastases. Recognising that the therapeutic benefit of removing normal nodes may be low, alternatives to the routine level I/II axillary lymph node dissection have been sought. A decade ago sentinel lymph node biopsy (SLNB) was introduced. Because of its high accuracy and relatively low morbidity, this technique is now widely used to identify women with histologically involved nodes prior to the formal axillary node dissection. Specifically, SLNB has allowed surgeons to avoid a formal axillary lymph node biopsy in women with histologically uninvolved sentinel nodes, while identifying women with involved sentinel nodes who derive the most benefit from a completion axillary node dissection. Despite the increasing use of SLNB for initial management of the axilla in women with breast cancer, important questions remain regarding patient selection criteria and optimal surgical methods for performing the biopsy. This article discusses the evolution of axillary node surgery for women with breast cancer.
