Diagnostic procedures are initiated when the symptoms already described appear. The physician will take a thorough medical history and conduct a physical examination in which he or she will feel for lumps in the scrotum, back and abdomen to see if the potential cancer has spread. One or more imaging studies will be conducted along with blood testing.
Ultrasound – Ultrasound imaging, a type of imaging that uses sound waves rather than radiation, will detect testicular tumors and determine whether they are solid or filled with fluid.
Blood tests – Some testes tumors make "markers" which are detectable in the blood. Measurement of these helps determine the type cancer, the stage (how far it has spread), and the best treatment.
