All of the following can be done EXCEPTChest xrayCt abdomenInguinal explorationTesticular biopsy  <response>: A testicular biopsy more specifically a trans-scrotal testicular biopsy is not done, rather is contraindicated.

A trans-scrotal testicular biopsy would breach anatomical barriers and would spread the tumor.
