Big friggin IF. Because of course, no cancer patient has ever died under the "care" of conventional medicine who immediately entrusted themselves to the "big boys," right?
Yes, sometimes even the best available conventional method is not enough to defeat cancer. And if a conventional method can't do it, no way in hell can a natural method do the trick. Again, no one died from conventional treatment who would have survived if given natural "treatment". Cancer and other diseases are nature's population control, why would nature willingly give you the tools to cure those diseases? Lastly, if natural cures were effective, humans would have never had to invent modern medicine because they would have figured out these natural remedies millennia ago and wouldn't have died in their 50's.
