What is an ovarian cyst?

An ovarian cyst is a fluid-filled sac that grows in or on an ovary. You have 2 ovaries, 1 on each side of your uterus. They are small, about the size and shape of an almond. Ovarian cysts are common in women who have regular monthly cycles. During your monthly cycle, eggs are released from the ovaries. The cyst usually contains fluid but may sometimes have blood or tissue in it. Most ovarian cysts are harmless and go away without treatment in a few months. Some cysts can grow large, cause pain, or break open.
