Symptom Checker: Symptoms & Signs Index
Medical Author: William C. Shiel Jr., MD, FACP, FACR
Breast discharge is the spontaneous flow of fluid from the nipple at any time other than during nursing. Breast discharge can be caused by a wide range of disorders, including breast cancer, breast ectasia, and breast infection. Sometimes it's possible to feel breast cancer as a breast lump. The breast lump may or may not be painful or tender. Breast duct malformation (duct ectasia) can lead to breast discharge. Mastitis is the medical term for a breast infection, and mastodynia is the medical term for breast pain. Another name for the nipple is areola. A physician should evaluate persisting breast discharge (nipple discharge).
