Diagnosis of a teratoma typically involves a combination of imaging studies and biopsy. Ultrasound, CT scans, and MRI are commonly used to visualize the tumor's size and location. A biopsy may be performed to analyze the tissue composition and determine whether the teratoma is benign or malignant. Blood tests for tumor markers such as alpha-fetoprotein (AFP) and beta-human chorionic gonadotropin (β-hCG) may also be useful in diagnosis.
