Went through a very similar situation with a 3+4 and 4+3 Dr recommended surgery then I found out out cancer not gone so 6 weeks of hormone treatment And radiation. At 78 and in very good shape otherwise I will always wonder how long I might have survived if I did nothing. The last year has been the worst time in my life and unable to get an erection makes it all worse , when my second hormone shot wears off I have one last chance of injection or penal transplant, anyone with experience of trying either one or both ?
