Diagnosis

A cyst on your ovary can be found during a pelvic exam or on an imaging test, such as a pelvic ultrasound. Depending on the size of the cyst and whether it's filled with fluid or solid, your health care provider likely will recommend tests to determine its type and whether you need treatment.

Possible tests include:

  • Pregnancy test. A positive test might suggest an early pregnancy. Corpus luteum cysts are normal to see during pregnancy.
  • Pelvic ultrasound. A wandlike device (transducer) sends and receives high-frequency sound waves to create an image of your uterus and ovaries on a video screen (ultrasound). The image is used to confirm that you have a cyst, see its location, and determine whether it's solid or filled with fluid.
  • Laparoscopy. A slim, lighted instrument (laparoscope) is inserted into your abdomen through a small cut (incision). Using the laparoscope, your provider can see your ovaries and any cyst. If a cyst is found, treatment is usually done during the same procedure. This is a surgical procedure that requires anesthesia.
  • Tumor marker tests. Blood levels of a protein called a cancer antigen often are elevated in ovarian cancer. If your cyst appears solid and you're at high risk of ovarian cancer, your provider might order a cancer antigen 125 (CA 125) test or other blood tests. CA 125 levels can also be elevated in noncancerous conditions, such as endometriosis and pelvic inflammatory disease.

Sometimes, less common types of cysts develop that a health care provider finds during a pelvic exam. Solid ovarian cysts that develop after menopause might be cancerous (malignant). That's why it's important to have regular pelvic exams.

Treatment

Treatment depends on your age and the type and size of your cyst. It also depends on your symptoms. Your health care provider might suggest:

  • Watchful waiting. In many cases you can wait and be reexamined to see if the cyst goes away after a few months. This is typically an option — regardless of your age — if you have no symptoms and an ultrasound shows you have a small, fluid-filled cyst. You may have several follow-up pelvic ultrasounds to see if your cyst changes in size or appearance.
  • Medicine. Hormonal contraceptives, such as birth control pills, keep you from ovulating. This may keep you from getting more ovarian cysts. But, birth control pills won't shrink an existing cyst.

  • Surgery. Your provider might suggest removing a cyst that is large, doesn't look like a functional cyst, is growing or causes pain. Some cysts can be removed without removing the ovary (cystectomy). In some cases, the ovary with the cyst is removed (oophorectomy).

    Surgery can often be done using minimally invasive surgery (laparoscopy) with a laparoscope and instruments inserted through small cuts in your abdomen. If the cyst is large or cancer is a concern, an open procedure using a larger cut may be needed.

    An ovarian cyst that develops after menopause is sometimes cancer. In this case, you may need to see a gynecologic cancer specialist. You might need surgery to remove your uterus, cervix, fallopian tubes and ovaries. You may also need chemotherapy or radiation.

Preparing for your appointment

Your first visit may be with your primary care provider or a specialist in conditions that affect the female reproductive system (gynecologist).

Think about bringing a family member or friend with you to the appointment, if you can. They can listen to what your provider says and help you recall information later.

What you can do

Before your appointment, make a list of:

  • Your symptoms, including those that seem unrelated to the reason for the appointment, and when they began
  • All medicines, vitamins, herbs and other supplements you take and the dosages
  • Your medical history, including menstrual irregularities
  • Questions to ask your health care provider

Questions to ask include:

  • What's likely causing my symptoms?
  • What tests might I need?
  • Will my cyst go away on its own, or will I need treatment?
  • Do you have printed materials or brochures I can have? What websites do you recommend?

Don't hesitate to ask other questions as they occur to you during your appointment.

What to expect from your doctor

Questions your provider might ask include:

  • How often do you have symptoms?
  • How bad are your symptoms?
  • Do your symptoms seem related to your menstrual cycle?
  • Does anything make your symptoms better?
  • Does anything make your symptoms worse?
  • Have you had ovarian cysts in the past?

Your provider will ask other questions based on your responses, symptoms and needs. Being ready to answer the questions will help you make the most of your appointment time.
