It's not total bunk, just 99.99% bunk. It wasn't all that long ago you would have been considered a quack to suggest you could treat most stomach ulcers with antibiotics.
True -- the usual treatment for ulcers was to deal with the acid instead of the bacillus that thrived in stomach acid. That a bacillus could thrive in stomach acids that all logic said would digest the bacillus was counter-intuitive.
It was not quackery, but conventional medicine, that discovered the connection between H. pylori and stomach ulcers. Medicine advances; quackery keeps suggesting copper bracelets for 'that pesky arthur-itis'.
Of course. But just because much cancer comes from using tobacco products does not mean that cancer is tobacco. Or, in view of another cause, radiation. Or viruses.
