Testicular cancer or Prostate, what are the top treatments for this now? What is the best?

I have a friend that has been diagnosed with cancer. I don't know if it is testicular or prostate, but I do know it is elsewhere in his body know. Does anyone know the best treatment for this? Any breakthroughs? There is so much info out there that it is mind boggling! He lives out of the States but I think he thinking of coming over to the U.S. to get treatment. I haven't talked to him in a while and it is hit and miss message :( Help please.
