How can sunburns and sun exposure cause permanent skin damage if your skin is constantly replacing itself?

Recently read something about how a few bad sunburns when you’re young can cause a large increase in cancer later in your life. How can you develop cancer several decades after you’re burnt if your skin cells are constantly dying, falling off, and regrowing?

We had a saying during Navy Nuke school: Good Daughters, Bad Daughters, Dead Daughters, No Daughters.

When your cells are exposed to ionizing radiation, it can cause mutations. When that cell reproduces, it can not pass on the mutation (Good Daughter), it can reproduce, but the daughters die (Dead Daughters), the cell could die (No Daughters), or it can pass the mutation on (Bad Daughters).

Cancer would be Bad Daughters, cells that mutate and then pass those mutations on.
