Ovarian cyst

Some ovarian cysts can cause symptoms, such as pain in your tummy, bloating and irregular periods.

Most ovarian cysts disappear in a few months without treatment. Large cysts or cysts causing symptoms may need to be surgically removed.

Ovarian cysts are fluid-filled sacs that can grow on the ovaries. Most cysts are harmless and disappear without treatment.

Most ovarian cysts are a normal part of the menstrual cycle. Some can be caused by abnormal cell growth or a condition such as endometriosis.
