Cysts -- fluid-filled pockets -- on the ovaries are more common in women who still have menstrual periods. They can also occur during pregnancy. Often, ovarian cysts don’t cause any symptoms. When they do, they can cause pain in your lower abdomen (particularly during your period) and bloating.
While rare, it is possible that cysts can be cancerous, which is why it is important for you to be seen by a doctor if you suspect you may have an ovarian cyst. Your doctor will perform tests to determine what type of cyst you have and to personalize your treatment.
