The medical community has been wrong about so many things, especially about diet, and what makes people fat, or susceptible to disease.
I would suggest that at best the cures are on the back burner while the money is on the front burner.
That is more time and effort is spent on developing treatments rather than cures, as it makes sense for a for profit business.
It is like the old joke of looking for lost car keys under that street lamp because the light is better, instead of looking for the keys where they might actually have been lost.
The money is the light.
The thing that is overlooked when people denounce something as a conspiracy theory is that all those theories have elements of truth and fact. It is like throwing out the baby with the bath water.
Surgery, radiation, and drugs are not the cures for these diseases, but they are treatments that have some success. We have made great strides in surgery, not so much with radiation, and drugs.
Only the people that have developed a cure actually know about it, that is if in fact there is a cure.
