Obviously yes, so is most chronic disease, but bring up people being healed by lifestyle & diet intervention and prepare for relentless attacks from both doctors and laypeople.
Isn't that just selection bias, as diets get westernized so does medical care and so we detect more diseases..
this is even counter to mainstream medical opinion
Life expectancy also goes up as lives get westernized, so people live long enough to become adults and die from cancer, rather than Malaria, diarrhea, etc
rates of cancer are going up in younger people nowadays
Diet is not the only factor for cancer. There are children who die of cancer, and there are smokers and drinkers that live to 99.
