Ovarian Cysts
Ovarian cysts are common findings and are usually benign. The key question is whether a cyst can be safely monitored or whether it needs targeted treatment because of symptoms, size or suspicious features.
Symptoms of ovarian cysts
Most ovarian cysts do not cause symptoms and are found during a routine gynecological ultrasound. When symptoms appear, they depend on the cyst type, size and position.
- Dull or pressure-like pain in the pelvis or lower abdomen, often on one side.
- Bloating, abdominal fullness or a feeling of pelvic heaviness.
- Pain during intercourse, especially with deep penetration.
- Irregular periods, heavier bleeding or missed periods.
- Frequent urination or difficulty emptying the bladder when the cyst causes pressure.
- Constipation or pain with bowel movements when the cyst presses on the rectum.
When urgent assessment is needed
Sudden pain can indicate ovarian torsion or rupture of a cyst. These are urgent situations that need immediate medical evaluation.
- Sudden, severe abdominal or pelvic pain that does not settle.
- Pain with nausea, vomiting or fever.
- Dizziness, weakness or fainting together with abdominal pain.
- Fast heartbeat, pallor or feeling seriously unwell, which may suggest internal bleeding.
Risk assessment and follow-up
A biopsy is not usually used to diagnose an ovarian cyst before surgery. Risk is estimated from ultrasound features, age, symptoms and selected blood tests.
- Simple small cysts in premenopausal women often need only repeat ultrasound.
- Complex cysts, solid areas, thick septations, ascites or rapid growth need more detailed assessment.
- IOTA models or risk indexes may help classify the cyst and guide referral.
- Postmenopausal cysts need a lower threshold for investigation and specialist review.
Diagnosis of ovarian cysts
Diagnosis is based on clinical examination and imaging. Transvaginal ultrasound is usually the first and most important test.
- Gynecological examination: Assesses tenderness, pelvic masses and associated symptoms.
- Transvaginal ultrasound: Evaluates the cyst size, location and appearance, including whether it is simple, complex or solid.
- Pelvic MRI: Used when ultrasound findings are unclear or detailed preoperative mapping is needed.
- Tumor markers such as CA-125 and HE4: Used selectively, especially after menopause or when malignancy risk must be assessed.
Types of ovarian cysts
Not all ovarian cysts are the same. The type of cyst determines the risk, the follow-up plan and whether treatment is needed.
- Functional cysts: The most common type. They develop during the ovulation cycle and often resolve on their own within a few weeks.
- Endometriomas: Blood-filled cysts related to endometriosis. They may cause pain and affect fertility.
- Dermoid cysts: Usually benign cysts that can contain fat, hair or other tissue and may need removal if large or symptomatic.
- Cystadenomas: Benign ovarian cysts that can become large and cause pressure symptoms.
- Borderline ovarian tumors: Low malignant potential tumors that need specialist surgical assessment.
Treatment of ovarian cysts
Treatment depends on the type, size, symptoms and the woman's age and fertility plans. Many cysts do not need surgery.
- Observation: Repeat ultrasound in a defined time frame for simple functional cysts.
- Medication: Hormonal treatment may reduce the chance of new functional cysts in selected women, but it does not remove an existing cyst.
- Pain control: Short-term symptom relief while the cyst is being monitored or treatment is planned.
Surgical treatment
Surgery is recommended when a cyst is large, persistent, symptomatic or has suspicious imaging features, or when torsion or rupture is suspected.
- Laparoscopic cystectomy: Minimally invasive removal of the cyst while preserving the ovary whenever possible.
- Robotic laparoscopy: High-precision surgery for complex or difficult cysts with careful preservation of healthy ovarian tissue.
- Oophorectomy: Removal of the ovary in selected cases, such as suspicious cysts, very large cysts or postmenopausal women.
- Emergency laparoscopy: Used when torsion or rupture with bleeding is suspected.
Prevention and regular monitoring
There is no guaranteed way to prevent ovarian cysts, but regular gynecological follow-up helps detect changes early and avoid complications.
- Annual gynecological check-up with ultrasound when indicated.
- Prompt review for sudden pelvic pain or acute abdominal symptoms.
- Informing the doctor about family history of ovarian or breast cancer.
- Closer follow-up for women with known endometriosis or PCOS.
