Sorry folks, yes it totally can. I was extremely alkaline when my cancer started. Like edema level alkaline, and it grew just fine, until I zapped for parasites took olive leaf extract for the 'cancer' infection (actually a modified fungus that Dr.s aren't trained to recognize, of course), and then got a zapper with the frequency for fungus, and finished it off (got to a stage 3 liver tumor, before it caused any pain).
I think it used to be killed by alkalinity, but the 'elites' mutated it so it wouldn't be. And that's why now this information has 'come to light'. Cancer is their biggest money maker, and I'm sure they'll try to do anything to keep it that way.
