Living with Ovarian Brenner tumor

A solid growth on the ovary, usually non-cancerous, most often found after menopause and often without symptoms.

Understanding Ovarian Brenner tumor

Ovarian Brenner tumor is a solid, abnormal growth on the ovary that is usually not cancerous (benign).

It most often occurs in women after menopause. It usually causes no symptoms unless it is very large. When present, symptoms may include belly pain or vaginal bleeding. It is usually found by accident during surgery for another reason or a routine exam. Diagnosis is made by looking at a piece of the tumor under a microscope.

Signs & symptoms

Symptoms vary, and many people have none. GARD says they may include:

  • Belly pain
  • Vaginal bleeding
  • Usually no symptoms unless the tumor is very large

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Your doctor may refer you to a specialist who knows rare conditions.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
