Hey, A half-true Article!

On November 11, 1997, the following article appeared in the local paper.

While any article that questions the value of cholesterol lowering drugs is to be applauded, the article implies that there are "proven" health benefits to cholesterol lowering drugs. The brainwashing continues.

Question: If vitamin D helps prevent breast cancer, and if cholesterol is required with sunlight to make vitamin D in our bodies (it is), then do cholesterol lowering drugs contribute to breast cancer, in addition to the possibility they also cause Alzheimer's disease? This is the same logic, by the way, that medicine uses to connect vitamin C to kidney stones. No experimental proof. Why is this logic appropriate in one argument, but not another?
