Ovarian cyst overview and content structure

Ovarian cysts are liquid or semi-solid masses that form in or on the female ovary. They are mostly benign, but you need to be alert to the possibility of malignancy.This article will start from five aspects: definition, types, symptoms, diagnosis and treatment:1. Definition and Causes(physiological/pathological);2. Common types(Such as follicular cyst, corpus luteum cyst, etc.);3. Typical symptoms(Abdominal pain, abnormal menstruation, etc.);4. Diagnostic methods(Ultrasound, blood tests, etc.);5. Treatment options(observation, medication, or surgery).Focus on analyzing the difference between physiological and pathological cysts to help women deal with them scientifically.

Definition and causes of ovarian cysts

Ovarian cysts are fluid-filled sac-like structures in the ovaries. Most are formed naturally during the ovulation cycle (if the follicles do not rupture or the corpus luteum persists). They are calledphysiological cyst, usually disappears on its own within 2-3 menstrual cycles.A few arepathological cyst, such as chocolate cysts or tumor cysts caused by endometriosis.Abnormal hormone levels, pelvic infection, or genetic factors (such as BRCA gene mutations) may increase the risk.It should be noted that new cysts after menopause have a higher probability of malignancy and require timely investigation.

Common types and clinical manifestations

Ovarian cysts are mainly divided intofunctional cyst(more than 70%, related to menstrual cycle) andnon-functional cyst(such as dermoid cyst, serous cystadenoma).Most small cysts are asymptomatic, but they may cause symptoms if they increase in size or rupture.Lower abdominal distension, painful sexual intercourse or frequent urination.Rupture of a corpus luteum cyst may cause abdominal bleeding, manifested by sudden severe pain; endometriosis cysts may be accompanied by dysmenorrhea and infertility.If persistent fever, vomiting or abnormal vaginal bleeding occurs, be alert for complications.

Diagnostic methods and identification points

First choice for initial screeningtransvaginal ultrasound(Accuracy rate is over 90%), and can determine the size, location and internal characteristics of the cyst (such as septations, papillary protrusions).Blood tests such asCA-125(non-specific, elevated levels may indicate ovarian cancer or endometriosis) andHE4Assist identification.MRI or CT are used for complex cases.Doctors will make a comprehensive assessment based on age, symptoms and tumor markers to distinguish physiological cysts from ovarian tumors to avoid over-treatment.

Treatment Strategies and Health Management

Physiological cysts are usually recommendedReview in 3-6 months, no intervention is required.Pathological cysts are selected based on their nature:medicine(such as contraceptive pills to inhibit recurrence),minimally invasive surgery(laparoscopic dissection) orradical surgery(When suspected malignancy).Regular follow-up is required after surgery, especially for nulliparous women who need to preserve ovarian function.Avoid strenuous exercise on a daily basis to prevent cyst torsion, and a balanced diet (such as reducing high-estrogen foods) can help prevent it.Women over 40 years old are recommended to have annual gynecological examinations.
