What is the difference between a cyst and a polyp? 🤔 An ovarian cyst is a fluid-filled sac that develops on an ovary. They're very common and do not usually cause any symptoms. Most ovarian cysts occur naturally and go away in a few months without needing any treatment. 😓💉 Uterine polyps are growths that occur in the inner lining (endometrium) of your uterus. Uterine polyps are usually noncancerous, but they may cause problems with periods or fertility if they’re left untreated. 🤰 | New Hope
