Why are more people getting cancer?

Some diseases, like smallpox, are declining or have been almost completely eradicated. Yet in 2018 there were around 18 million cancer cases globally, and this is expected to hit 30 million in the next 20 years. People are living for longer, which is one of the main reasons for the increase in cancer rates as the longer we live, the more time we have to develop cancer. But there are other reasons why more people are getting cancer, and some are to do with how we live and what we do (or don't do).

Despite 30 years of WCRF, there is still more to be done to help people lower their risk of cancer.
