My 2 cents.

First Bluesinger, I wish you well in the endeavor. I probably ffear this more than cancer, or diabetes.

in my efforts to find information and to learn, in hopes of preventing this slow death, some writer link it to diet. Meaning LC is likely to be preventative.

Which is logical to me. THe rapid increase in the disease seems to follow the curve for obesity and heart attacks. JMHO

Like you I tend to seek non-drug options first. These days I reach to food as the first line of action.
