Patient's question:
2 years ago, there was a 67 cm cyst on the right ovary, which was surgically removed. Last year, during a check-up for irregular menstruation, a 86 cm cyst was found on the right ovary. After taking Chinese medicine, it reduced by 2 cm. However, after stopping the medicine for over a month, a follow-up check showed it had grown to 9.7 cm. Please ask the doctor if this is malignant.Doctor's answer:
Generally, cysts with a diameter greater than 5 cm are considered physiological, while those smaller than 5 cm are usually considered benign. Follow-up with ultrasound every 3 months is sufficient, as most cysts will shrink or disappear on their own. However, they may also grow back on the same or opposite ovary. If a cyst with a diameter greater than 5 cm is purely cystic, it is not usually harmful. The main risks are rupture, infection, or torsion, so surgical treatment is recommended.
