Maybe you’re conflating an increase in DNA damage with an increase in the rate of DNA damage. The data is consistent with:
One-time exposure to lots of DNA damage (nuclear bomb) → Increased cancer risk
Increase in background rate of DNA damage (aging, working near ionizing radiation) → Increased dementia risk
