I was diagnosed with an ovarian cyst. Is it cancer?

No, in the vast majority of cases, an ovarian cyst is not cancer. A cyst is just a fluid-filled sac, while cancer is a solid mass of uncontrolled dividing cells. Most cysts are benign, such as functional cysts, and often resolve on their own within a couple of months. Even the risk of a dermoid cyst turning into cancer is only 1–2%, and that is more common after age 45 or with large cysts. However, if the cyst is complex, it can be difficult to distinguish from cancer on ultrasound, so it is important to undergo a complete examination. There is no need to panic, but it should not be ignored either — it is best to consult a doctor.
