I have no idea what TC means. If its a solid tumor, it would be in the testicle and has a very HIGH chance of being cancer
( a seminoma
etc. If its in the CORD, and the epididymis is the CORD there is about ZERO chance of being cancer and MOST likely is an epididymal cyst. You leave it. But make SURE of the location. CORD or TESTIS. Big difference.
