I have fought this for 15 years. My experience is that not once did any of my doctors mention alcohol consumption. They did say restrict fatty processed meats and beef. (I was a heavy steak eater-doctors attribute steak to causing cancer-I have zero DNA markers for cancer)
Also I am not a big drinker- but I have had and continue to have social drinks. Usually two whenever I’m in that scenario. Wine or alcohol. Again-doctors (7) didn’t comment. Just my history.
