If you are making the point that we'd better address cancer or traffic accidents, then your argument falls under the false dichotomy fallacy. This is probably why you've been downvoted.
If your were not making this point, then I don't have the answer. :-)
Besides cancer numbers are a bit inflated because people are living more now. If you live long enough the odds of getting cancer is quite high. Whilst it's always good to extend life even more, even if it was a dichotomy, that seems less pressing than a diseases that are killing in their prime or even before they had a chance of having a good go.
