"Steve Jobs tried alternative treatment of his cancer
Then it got worse so he did normal doctors (part of "$1 trillion") but it was too late
He publically told people that was a mistake, don't substitue the ($1 trillion) doctors with the alternates"
I've met and talked to people who solely used "alternative" treatments for cancer and had great success with same. But that doesn't mean that all would.
Also, who knows if Jobs did it in an ideal way. "Alternative" is a really broad term with many, many different subcategories, theories, beliefs, applications, etc. Even diet alone is a huge and varied topic in alternative health of which there is not complete consensus on.
Also, there is the issue of following treatment, which in some ways, tends to be tougher and require more discipline with alternative treatments. To radically change ones diet (the core foundation and key starting point for many "alternative" treatments), takes so much discipline and self will, which even in the face of death, a lot of people i've met seemingly aren't willing to consistently and seriously enact same.
One lady i talked to at a health conference, successfully treated and got rid of cancer from radically changing her diet.
To see the power of diet and foods on health in a entertaining, touching, and enlightening way, check out the documentary called, "Fat, Sick, and Nearly Dead." It's on netflix instant.
