Ovarian cysts are usually fluid-filled lumps that may occur on one or both of the ovaries at any time in a woman’s life. Occasionally they are solid, if so, they are regarded as tumours, a medical term for ‘swelling.’ Often cysts are discovered by doctors during a routine examination. At other times, they may cause pain or a noticeable swelling, and need urgent attention. Because cysts can be malignant (i.e. cancerous) they should be treated as soon as possible. But a vast majority of cysts are not cancerous.
We recommend the RCOG patient information leaflets for the most up-to-date and detailed information.
