An ovarian cyst is a fluid-filled sac or pouch in the ovary.  In most cases, the cyst grows as a result of ovulation (when the egg is released from the ovary), and it will usually shrink over time. Sometimes, the ovarian cyst may cause pain.

 

The best way to check for an ovarian cyst is by ultrasound examination, and the treatment will depend on how troublesome the symptoms are. Sometimes it is best to leave the cyst alone and just check it regularly with ultrasound. In other cases it may need to be removed by laparoscopic surgery.
