Gabriel,
I suggest for your father to get the Path report and the slides and have them sent to Mainland Spain for a second look. It seems to me it would be beneficial to see if another Dr. at a major cancer center agrees with the course of action that this Dr. wants to proceed with. If he does great. If he doesn't, your father may still be able to get whatever treatment is recommended close to home, but the guidance would be coming from the larger facility. You have a bit of time to get this done as he doesn't want to start treatments for a month.
I still suggest getting scans done to check for any further spread...
Gabriel, just have him get a second opinion regardless if it is in the Canaries, or Spain...
I always tell people that they wouldn't buy the first car or house they look at, why buy the first opinion?? Always check, then double check, do research, It could be that the first one was the best, but being a good consumer means seeing what else is out there.
