You really have to put things in context, otherwise you get into the "think of the children" fallacy, where everything is worth the effort if it saves one life.

We die of three causes: cancer, heart problems and strokes. Well over 30% die of cancer. So this means some of those 200 will die of cancer before they die of something else (some of them will recover and live to die from heart attack later). This makes the new deaths a really tiny percentage, which means policy-wise it's hardly worth discussing.
