The number of people you know who have or die of cancer grows exponentially with age once you are an adult.

In 20s-early 30s, maybe 0 if your parents/uncles/aunts are lucky. You can be completely oblivious to it if your older relatives manage to escape it.

By 40 you start hearing about friends having it pretty routinely. We seem to have hit a one close friend per year pace at the moment.

Every time I talk to my 70+ parents, they are telling me about a funeral they've been to recently, often caused by either cancer or heart disease.
