Serous cystadenomas are benign tumors that typically develop in the ovaries. They are filled with a clear, watery fluid and are often discovered during imaging tests or routine examinations. These tumors are usually asymptomatic, meaning they do not cause noticeable symptoms, but they can sometimes lead to abdominal discomfort or pressure. These cystadenomas are characterized by their smooth, thin walls and can vary in size. While they are generally non-cancerous, monitoring is essential to ensure they do not change or cause complications. Surgical removal may be recommended if they grow large or cause symptoms.
