Teratomas have a genetic predisposition, but it is not certain how likely they are to be inherited. Studies have found that having a family history of teratoma increases the risk of developing the disease; having a genetic disorder, such as Klinefelter syndrome or Turner syndrome, increases the likelihood of developing a teratoma. A teratoma is a tumor that originates in the germ cells. Most patients have no obvious clinical symptoms, while a few may present with symptoms such as abdominal pain, bloating, and abdominal masses. Given that teratoma has the possibility of heredity, women with a family history of teratoma must pay attention to regular medical checkups in the hospital, improve the alpha-fetoprotein, human chorionic gonadotropin, serum tumor markers and other related tests, to clarify the specific causes of teratoma.
