AFAIK, child molestation victims are not more likely to become pedophiles or molest children; usually they’ve got a lot of PTSD.

The only treatment that’s available is chemical castration (to largely eliminate sexual urges, although that creates a ton of health issues), and therapy that reduces the probability of criminal offenses against children. It’s not treating pedophilia per se, it’s helping people learn to avoid triggers and spaces where they’re likely to feel overwhelmed by sexual impulses. There’s no cure.
