What is a Brenner tumor?

Can a Brenner tumor come back after it is removed?
While Brenner tumors usually don’t recur, one study showed that in about 28% of cases, the tumor comes back after it is removed. [1] [3] [5] The long-term outlook for individuals with cancerous or borderline Brenner tumors depends on the stage of the cancer when it is diagnosed and if the cancer has spread beyond the ovary.
What are the chances of a Brenner tumor spreading?
About 5% of Brenner tumors are cancerous (malignant) or have a small chance of spreading beyond its original location (borderline). These tumors most often occur in women after menopause.
What is the long-term outlook for patients with borderline Brenner tumors?
The long-term outlook for individuals with cancerous or borderline Brenner tumors depends on the stage of the cancer when it is diagnosed and if the cancer has spread beyond the ovary. In general, the earlier the tumor is diagnosed and the less it has spread, the better the outcome. [5]
