ELI5: If cancer is due to damages DNA, how do children, with newer DNA, get cancer so often?

Children can be created with damaged DNA from their parents, as gametes (sperm and egg) pull their DNA from the parent, which may have mutated locally.

In fact, such mutations causing the fetus to be non-viable can trigger the female's body to spontaneously abort the pretnancy, commonly known a miscarriage.
