What is mammography?

A mammogram is an X-ray examination of the breasts. This is performed when a person, their doctor or another health professional discovers unusual signs or symptoms in one or both breasts, i.e. a lump, tenderness, nipple discharge or skin changes. The mammogram confirms whether the changes are benign (non-cancerous) and no treatment is needed, or whether the changes indicate breast cancer and further tests and treatment will be required.
