I'm sorry to hear about your misfortune . However, some of the best ways to combat cancer are non-smoked cannabis (just the THC itself), eating lots of strawberries and rasberries (anti-cancer properties), and reducing stress as much as possible. Also I have heard of some people living a life of healthy eating and lots of meditation, and have actually cured themselves of it. This is all I can offer for now.

BTW, do you or have you smoked tobacco or anything else?
