👉 An ovarian cyst is a type of benign tumor that grows in the ovary. It can cause pain, swelling, and sometimes bleeding when it bursts. The treatment for an ovarian cyst depends on how large the cyst is and if it causes any other health problems. In some cases, it may be removed through surgery or medication to reduce the size of the cyst. If the cyst is not causing any significant issues, it might just need to wait until it grows larger again.
