Are ovarian cysts dangerous? 

Most ovarian cysts are not dangerous and go away on their own without treatment; however, in some cases, an ovarian cyst can twist or burst, which is a medical emergency. Go straight to A&E or call an ambulance if you have sudden, severe pelvic pain, especially on one side, that may be accompanied by weakness, dizziness, vomiting, rapid breathing or heavy bleeding.

In rare cases, an ovarian cyst may become malignant (cancerous). This is more common if you’ve been through the menopause. Your gynaecologist may recommend regular blood tests and ultrasound scans if you are at risk of developing a malignant ovarian cyst.
