Serous cystadenoma is a type of benign tumor that typically forms in the ovaries. It is filled with a clear, watery fluid and is usually asymptomatic, meaning it often does not cause noticeable symptoms. These tumors are most commonly found in women of reproductive age and can vary in size. Diagnosis is usually made through imaging techniques like ultrasound or CT scans. While serous cystadenomas are non-cancerous, they may require monitoring or surgical removal if they grow large or cause discomfort. Regular check-ups can help ensure they do not develop into more serious conditions.
