An ovarian cyst is any collection of fluid, surrounded by a very thin wall, within an ovary. Any ovarian follicle, that is larger than about two centimetres, is termed an ovarian cyst. Such cysts range in size from as small as a pea to larger than an orange.
- Most ovarian cysts are functional in nature and harmless (benign)
- Ovarian cysts affect women of all ages. They occur most often, however, during a woman’s childbearing years
- Some ovarian cysts cause problems, such as bleeding and pain in which case surgery may be required.
Functional cysts and haemorrhagic ovarian cysts usually resolve spontaneously. However, the bigger an ovarian cyst is, the less likely it is to disappear on its own. Treatment may be required if cysts persist over several months, grow or cause increasing pain.
