Most ovarian cysts are benign and resolve on their own. Some need attention.
Functional cysts (follicular and corpus luteum) usually resolve. Endometriomas, dermoids, and persistent cysts often need follow-up or treatment.
Severe pain, rapidly enlarging mass, complex features on ultrasound, fever, or signs of torsion or rupture require urgent evaluation.
Observation, hormonal therapy, or surgical removal depending on type, size, and symptoms. Fertility goals are factored in.
