Brenner tumor of ovary

Disease Overview

Brenner tumor of the ovary is a solid, abnormal growth (tumor) on the ovary. Most Brenner tumors are not cancerous (benign). About 5% of Brenner tumors are cancerous (malignant) or have a small chance of spreading beyond its original location (borderline).[1273][15028][15029] These tumors most often occur in women after menopause. They usually do not cause symptoms unless they are very large.[1273][15029][15030] When symptoms are present, they may include abdominal pain or vaginal bleeding.[15028] The cause of Brenner tumors is unknown. They are usually found by accident during surgery for another reason or during a routine doctor’s examination. The diagnosis is made by microscopic examination of a piece of tumor obtained by a surgical biopsy. Treatment usually consists of surgery to remove the tumor.[15028][15029][15030] If a Brenner tumor has not spread into surrounding tissues or to more distant parts of the body, there is a good-to-excellent long-term outcome.[1273][15028]
