The basics
What is an ovarian cyst?
An ovarian cyst is a fluid-filled sac on or in an ovary. They are very common in women who still have periods, and most are found by chance on a scan.
The most common type is a functional cyst, which forms during ovulation and usually disappears within one to three cycles. Other types include chocolate cysts from endometriosis, dermoid cysts and cystadenomas, which do not go away on their own.
The type, size and look of your cyst on ultrasound decide what happens next. Most cysts are benign, and your doctor tells you clearly if anything needs further tests.
Know your cyst Common types of ovarian cyst
- Functional (follicle or corpus luteum) cyst, often resolves by itself
- Endometrioma or chocolate cyst, linked to endometriosis
- Dermoid cyst (mature teratoma), contains tissue like hair or fat
- Cystadenoma, a benign growth from the ovary surface
- Many small follicles, which can point to PCOS
This page vs. removal
- This page covers diagnosis and all options. For the procedures themselves, see ovarian cyst removal
- Ultrasound alone cannot prove a cyst is benign. See ovarian cancer screening
Signs and symptoms
Ovarian cyst symptoms and when to see a doctor
Many cysts cause no symptoms at all. When they do, these are the most common signs.
Reasons for closer follow-up
- A cyst larger than 5 cm
- A cyst that does not shrink after 2 to 3 cycles
- Solid parts or unusual features on ultrasound
- A cyst found after menopause
- A family history of ovarian or breast cancer
Get emergency care if you have:
- Sudden, severe pelvic pain
- Pain with fever, vomiting or fainting
- Fast breathing or feeling very weak
A cyst can burst or twist the ovary (torsion). Go to the nearest hospital emergency room, then message us on WhatsApp.
Your options
Ovarian cyst treatment options
Treatment ranges from doing nothing at all to surgery. Most women need one of the first two.
Watchful waiting
A simple cyst is rechecked by ultrasound after 6 to 12 weeks. Many disappear on their own, and your doctor may suggest checks twice a year.
Simple functional cystsMedicine
Hormone pills or other medicine may be used to calm cysts linked to endometriosis or to stop new functional cysts forming, plus painkillers when needed.
Recurring or painful cystsSclerotherapy or surgery
Persistent cysts can be drained through the vaginal wall and treated with a sclerosing agent, or removed by laparoscopy. See ovarian cyst removal.

How to prepare
- Note the first day of your last period. Timing matters for functional cysts.

- An empty bladder makes a transvaginal scan more comfortable.
What watchful waiting means
Watching is an active plan, not ignoring the cyst. You come back for a scan after a few cycles, usually just after your period, when functional cysts are smallest.
If the cyst grows, changes or causes pain, your doctor talks about the next step.
