If you have high cholesterol, you have less cancer.
If you are fat you have more cancer.
So is it because folks with high cholesterol take statins?
When statins first came out, the joke was that they lowered your death rate from heart disease, but the death rate stayed the same: one study showed an increase in bowel cancer in that group, another showed an increase in homicide/suicide.
later studies showed it was a coincidence.
So this is just an early question that needs investigation
