Seminoma

 

a tumor of the sexual glands that is usually malignant. Primarily occurring in young men, seminoma affects the testis. Cryptorchidism predisposes an individual to the development of this type of tumor, which metastasizes predominantly along the lymphatics. Seminoma is treated surgically, medicinally, and through radiotherapy.
