From 1991 to 2018, the cancer death rate has fallen 31%. This includes a 2.4% decline from 2017 to 2018 – a new record for the largest one-year drop in the cancer death rate. These are just some of the findings from the annual statistics reported by the American Cancer Society (ACS).

What is cancer incidence?

A cancer incidence rate is the number of new cancers of a specific site/type occurring in a specified population during a year, usually expressed as the number of cancers per 100,000 population at risk. That is, Incidence rate = (New cancers / Population) × 100,000.

Why is cancer so common now?

The main reason cancer risk overall is rising is because of our increasing lifespan. And the researchers behind these new statistics reckon that about two-thirds of the increase is due to the fact we’re living longer. The rest, they think, is caused by changes in cancer rates across different age groups.

What are the top 3 most common new case cancer types?
