Teratomas are mostly diagnosed through symptoms, such as abdominal pain or bloating, and are identified with an ultrasound examination. Generally, these two tests are used. Additionally, blood tests may be conducted, but there are no very specific tumor markers that will be revealed. The primary means of diagnosis still rely on ultrasound and gynecological palpation. If a woman of childbearing age experiences unexplained abdominal pain, feels bloated, or notices occasional increases in abdomen size, it is recommended to undergo a gynecological ultrasound examination at a hospital.
