Cancer risk is so complex, and drawing conclusions when isolating one factor is always dicey, regardless of the validity of the statistical analyses. Exceptions are when the risk is super high, like with smoking. But let’s be clear, alcohol is a harmful substance in so many ways. There’s a reason mammalian livers evolved to rapidly detoxify ethanol. Exposure in nature is ubiquitous, and the effects can be quite harmful. Driving while impaired can be lethal, and so too can being a prey animal while impaired. In nature, the long term effects of ethanol consumption would rarely be uncovered, but in modern humans these effects are all too clear.
