Ovarian Cyst
Last Updated: July 3, 2026
Key Points
- Fluid-filled sacs on ovaries
- Very common and usually harmless
- Often cause no symptoms
- Most disappear naturally within months
- Can cause pain if large, ruptured, or twisted
Overview
The ovaries are two almond-shaped organs in the female reproductive system, located on each side of the womb. They release eggs monthly and produce important sex hormones like oestrogen and progesterone. An ovarian cyst is a fluid-filled sac that forms on an ovary. Ovarian cysts are very common and often occur naturally as part of the menstrual cycle (functional cysts). These are usually harmless and short-lived. Less commonly, cysts can form due to abnormal cell growth (pathological cysts) or underlying conditions like endometriosis. Most ovarian cysts are non-cancerous, though a small number can be cancerous, especially after menopause. Most cysts go away on their own within a few months without needing treatment. However, if a cyst is large, causes symptoms, or is suspected to be cancerous, medical attention and potential treatment may be necessary.
