An ovarian cyst is a sac or pouch filled with fluid or other tissue that forms on the ovary. Ovarian cysts are quite common in women during their childbearing years. A woman can develop one cyst or many cysts. Ovarian cysts can vary in size. In most cases, cysts are harmless and go away on their own. In other cases, they may cause problems and need treatment.
There are different types of ovarian cysts. Most cysts are benign (not cancerous). Rarely, a few cysts may turn out to be malignant (cancerous).
Most ovarian cysts are small and do not cause symptoms. Some cysts may cause a dull or sharp ache in the abdomen and pain during certain activities. Larger cysts may cause torsion (twisting) of the ovary that causes pain. Cysts that bleed or rupture (burst) may lead to serious problems requiring prompt treatment.
An ovarian cyst may be found during a routine pelvic exam. If your health care provider finds an enlarged ovary, tests may be recommended to provide more information:
Combined hormonal birth control pills may be prescribed to treat some types of ovarian cysts. This treatment will not make cysts you already have go away. But it may reduce the risk that new cysts will form.
If your cyst is large or causing symptoms, your health care provider may suggest surgery. The extent and type of surgery that is needed depends on several factors:
Sometimes, a cyst can be removed without having to remove the ovary. This surgery is called cystectomy. In other cases, one or both of the ovaries may have to be removed. Your doctor may not know which procedure is needed until after the surgery begins.
