How to determine when your ovarian cyst is going to ovarian cancer?

Ovarian Cyst/cancer: Ovarian cysts can develop into ovarian cancer over a very long time but not all ovarian cysts will become cancers. Simple cysts are rarely cancers regardless of the size. However, it there are abnormal areas within the cyst or it stays around for a long period of time, it needs to be evaluated.
