I'm sorry about your dad. Don't want to be a downer, but chemo killed my dad. It destroyed his immune system so much he didn't live and he'd been fighting it for 4 years prior to the chemo.
Have you tried esiac? (anti-cancer remedy) - also green tea, just pure green tea with nothing in it, tastes foul but that is anti-cancer and fights free radicals which destroy human tissue.
Also megadose vitamin C to build up his immune system, especially if he wants the surgery and chemo.
In animal tests, the rats who were given megadose vitamin C always survived and the ones who weren't supplemented didn't.
I know people are different to rats but its worth knowing.
I hope this doesn't offend - just meant to be friendly advice from someone who lost her dad at age 18.
