I've got a question. If they find cancer cells in a male testicles, does that mean they have cancer and do they give treatment for cancer cells?

Testis cancer causes. A lump in a testicle. We check markers (alpha feto protein, hcg). We remove the testis through the inguinal canal/incision. We do not violate the scrotum. We assess for nodes by ct scans of the para-aortic and kidney hila. We do not sample "cells" but look at the tumor in place after it is removed. Different cell types get different treatment. These are cancers.
