Tendernous is frequently associated, especially just before the menstrual period begins. If the fluid that is withdrawn is brownish or yellowish and contains no blood, and the lumps disappear after the procedure is completed, no further study is necessary. An intraductal papilloma is a small growth inside a duct of the breast. It is harmless and frequently cannot be felt. In some cases the only symptom is a watery, pink discharge from the nipple.
Surgical removal is recommended.
On occasion, an injury to the breast will cause a hematoma. This is characterized by a bruised area on the skin with an associated lump underneath. This lump is a blood clot formed by the collection of blood in the traumatized area. The area may swell and be tender, but should slowly return to normal. This may take a few days or a few weeks, depending on the injury.
