I think that you are missing the point. Hulda Clark 's claim is that ALL cancers are caused by a parasite (a rare parisite) that is native to SE Asia. I would think that claim is very difficult to believe, but easy to prove - check the livers of people whe die from cancer. Why hasn't anyone else noticed 4 inch long parisites in people's livers? Because they aren't there that's why. I don't care if Hulda Clark believes that parasites are the cause of cancers or not, what bothers me is when someone who could be treated with things that work choose not to and instead follow the guidelines of people who's treatments don't work.
