Ovarian cysts — fluid-filled sacs in or on the ovary — are remarkably common. The majority are completely harmless and resolve on their own, but a smaller subset deserves closer attention. Knowing which is which prevents both unnecessary worry and missed problems.
The most common types: functional cysts arise from normal ovulation and usually disappear over 1–3 cycles. Endometriomas ("chocolate cysts") form from endometriosis tissue and often cause painful periods and fertility issues. Dermoid cysts are benign but unusual growths that can contain hair, skin, or even teeth. Cystadenomas are benign tumours that can grow large over time. True ovarian cancer is rare in cysts under age 40, but any solid component or rapid growth raises concern.

At THE FIT CLINIC, we use high-resolution ultrasound and, when indicated, CA-125 and other tumour markers to risk-stratify cysts. Many simply need observation; others benefit from medication; a few require laparoscopic surgery. The decision is always individualised.
