[|Human|] I was diagnosed with a thymoma or germ cell tumor last week.  the size of tumor is 5.1x4.9cm.  the mass was seen within the superior mediastimum abutting the superior vena cava and ascending oarta. My question is.... Is this a cancer type of tumor? thanks
[|AI|]  To know exactly whether its Thomas or germ cell tumor, a biopsy and histopathological examination will be required. In germ cell tumor, tumor markers including serum AFP, serum beta Chat Doctor and serum LDH are sometimes also raised and will aid in diagnosis. Germ cell tumor is a cancer and Thomas has subtypes ranging from benign lesion to thy mic carcinoma which is malignant. Biopsy will give the exact diagnosis. I hope it helps. Please discuss with your doctor.
