Conditions & Treatments

Ovarian Cysts

Ovarian cysts are fluid-filled sacs that form on or inside the ovary. Most are benign and settle on their own, but some cause pain, pressure or need to be removed.

At The Pelvic Clinic Mr Broome offers pelvic ultrasound, tumour marker blood tests and expert laparoscopic surgery, with careful monitoring of cysts that do not need treatment.

Overview

What are ovarian cysts?

An ovarian cyst is a sac of fluid or semi-solid tissue that develops on or within an ovary. The great majority form as part of the normal ovulation cycle and resolve by themselves.

Cysts become clinically important when they are large, persistent, painful, or have features on ultrasound that need further assessment. Most women with cysts have no symptoms at all.

What to Look For

Symptoms of ovarian cysts

Pelvic pain or ache

A dull ache low in the pelvis, sometimes only on one side.

Sharp pain around ovulation

A sudden, brief pain mid-cycle that can occasionally be severe.

Bloating and pressure

A feeling of fullness or a visible swelling of the lower abdomen.

Pain during sex

Deep pain during intercourse, particularly in certain positions.

Changes in your cycle

Periods that become heavier, lighter or irregular as the cyst persists.

Frequent urination

Needing to pass water more often as the cyst presses on the bladder.

Sudden, severe pelvic pain with an ovarian cyst can mean torsion of the ovary and needs urgent assessment on the same day.

What Causes It

Causes of ovarian cysts

Ovarian cysts have several distinct origins. The most common are described below.

A menstrual cup with spilled blood on a pink surface, symbolizing menstruation and women's health.

Functional cysts

Follicular and corpus luteum cysts form as part of the normal menstrual cycle. They are the commonest kind and almost always resolve within two or three cycles.

Endometriomas

Also called chocolate cysts. They form when endometriosis affects the ovary and are filled with old blood. They rarely resolve on their own.

Dermoid cysts

Benign germ-cell tumours that can contain hair, skin or fatty tissue. They rarely shrink and are usually removed to prevent ovarian torsion.

Cystadenomas

Benign growths of the surface cells of the ovary. They can grow large, cause pressure symptoms and usually need surgical removal.

Treatments Available

How we treat ovarian cysts

Many cysts settle on their own; some need removal. We take the time to work out which yours is and, when surgery is needed, take the ovary-sparing approach.

Observation with Scans

Small, simple cysts are usually monitored with follow-up ultrasound. Most functional cysts resolve on their own within a few months.

Hormonal Suppression

A short course of the combined pill or the Mirena coil calms the ovary and prevents new functional cysts forming. Useful for recurrent cysts.

Laparoscopic Cystectomy

Keyhole removal of the cyst while preserving as much healthy ovarian tissue as possible. Most women go home the same day.

Oophorectomy

Removal of the ovary itself, usually keyhole, for complex or recurrent cysts. Always discussed carefully alongside your age and fertility plans.

Common Questions

Frequently asked questions

Answers to the questions patients ask most often about ovarian cysts, imaging and surgery at The Pelvic Clinic.

Are ovarian cysts dangerous?

The great majority are benign and pose no risk. Assessment is important to identify the small minority that need active treatment or surgery.

How are cysts diagnosed?

A pelvic ultrasound is the first-line test. Blood tests for tumour markers and, for complex cysts, an MRI scan may be added.

What are the symptoms of an ovarian cyst?

Most cysts cause no symptoms. When they do, symptoms include pelvic pressure, bloating, pain during sex, and pain around ovulation or during periods.

When do cysts need to be removed?

When they are persistent, larger than about 5 cm, painful, twisting the ovary or have suspicious features on imaging.

What is ovarian torsion?

When a cyst twists the ovary on its blood supply, causing sudden severe pain. It is a surgical emergency and needs urgent laparoscopy to save the ovary.

Will surgery affect my fertility?

Laparoscopic cystectomy is designed to preserve as much healthy ovarian tissue as possible. Most women retain normal ovarian reserve and fertility.

Are cysts linked to ovarian cancer?

Most cysts are entirely benign. Age, ultrasound appearance and blood tests together give a very accurate picture of risk before any surgery is planned.

Can cysts come back?

Functional cysts can recur cycle to cycle and often need no treatment. Endometriomas can recur and are sometimes managed with hormonal treatment after surgery.

How long is recovery after keyhole surgery?

Most women go home the same day, are back to desk work in a week and to normal activity within two to three weeks.

How quickly can I be seen?

Self-pay and insured patients are usually seen within a week or two. An ultrasound is arranged at or shortly after the first appointment.
