How effective are statins in preventing lung cancer?

Statins have been shown to have promising and potential effects in chemo-prevention, meaning preventing and reducing the risk of cancer development. In a recent study, this was a retrospective case control study that was recently reported, and statins have shown to reduce the risk by 55%. That study has limitations and it warrants validation with better studies with prospective randomized trials, so until then it's unclear if statins should be recommended currently. It's really being investigated, but certainly there's potential that it may have a preventative role.
