I believe, as you hint towards, that the ultimate way to reduce cancer risk is to cure ageing. Most cancers are rare in your 20s and 30s, then get dramatically more common every year after from your mid 40s roughly. To me, this suggests that the mechanisms that stop you getting cancer (and your body/DNA repairing in general) are themselves failing. Of course, if everyone was 25 forever we'd still all eventually die of cancer, but it would take a lot longer than the current state of affairs.
