?? Males who regularly drink apparently have increased rates of prostrate cancer, but that is plausibly directly due to the ethanal that arises during the breakdown of ethanol. Sorry - the only cancer example I can think of that is almost certainly due to a weird correlation rather than due to direct exposure to ethanal is an example that only works for cis females.
If I’m correctly remembering an episode of “Scrubs”, cis males do sometimes have tiny amounts of breast tissue, so there is a very low probability of them developing breast cancer, but I suspect the probabilities are so low that the researchers won’t be able to make any statistically robust conclusions about whether alcohol consumption changes the risk. Sometimes obese cis males might look like they have breasts, but it’s fat tissue rather than breast tissue, so doesn’t create extra breast cancer risk.
