It depends on how bad the scars are. If they are deep or raised (keloid) then cosmetic surgery with with radiation treatments is an option. It should be a last resort though. I'd try laser treatments first. If that doesn't work, talk with your doctor about possible scar revision surgery. Just remember, that it will still leave a scar. You can't get away with no scar at all.
Another option is to get a tattoo to cover your scars. Just a few things to think about.
