Tanchouism relates the idea of civilization to cancer incidence.





Vital Statistics: Illustrated by the Laws of Mortality from Cancer.


Important Text:


After having been acting president of the University of California through its first year, LeConte reverted to a mere professorship, and to writing (and perhaps lecturing?) upon the incidence of cancer. In his third San Francisco year he published, through the local Western Lancet, for March 1872, an article in which he again put forward “Tanchouism,” this time in connection with an appeal for more frontier information bearing upon the doctrine. This article is “Vital Statistics: Illustrated by the Laws of Mortality from Cancer.”

Presumably this second article, published in between LeConte's two presidencies of the university, was the one which — directly or through notice in other medical journals — reached Dr. Knight and thus may have initiated the Leavitt frontier search for malignant disease.

Cancer is a metabolic disease where the mitochrondria are no longer able to burn fatty acids and instead rely on fermentation of glucose and glutamine. Ketogenic diets have been used to prevent and cure cancer, as they induce a metabolic stress on cancer cells who cannot use ketones as fuel.
