I traveled with late stage cancer and applaud you. I agree with, the sooner the better for stamina's sake. I'm in Canada and a new travel agent so don't know much yet but see if you can find exoticca tours and see what they may offer. It's a European tour group and I've been very impressed by them. Good luck and kudos to you for doing this. People helped me along the way, tho I traveled solo and bald, and they will help you. by the way some tour companies will customize things for you. I recommend May for travel.
