Answer 1

* we are way better at diagnosing cancer, in the past many cancers deaths were categorized as natural causes
* in the past, people died of other disease or from injuries before they could get cancer, today they live long enough to die of cancer instead
* cancer is not a single disease, it is a huge class of disease, saying a lot of people die of cancer is likely saying a lot die of infection, rather than breaking it down to specific diseases
