Breast medicine specialises in the diagnosis, management and treatment of conditions associated with female (generally) and male breasts. This may include assessing any abnormalities or changes to the breasts and nipples. Most women experience breast changes at some time. Age, hormone levels and medicines may cause lumps, bumps, discharges, skin irritation and pain. Minor and serious breast problems have similar symptoms, so it is important to check problems with your health provider. Most breast problems do not involve cancer.
