I have a close friend who had the same recommendation from his doctor, i.e. to go vegan. His genetics were predisposed for food-driven health issues related to cholesterol as he aged, and his blood test continued to come back with bafflingly concerning results. Since going vegan, his blood work has been stellar. It drives his family nuts sometimes, but the results are hard to argue and they've learned to "deal". Everyone is different, but in his anecdotal case his doctor's recommendation to go this route seems to have helped him quite a bit. It's worth noting that he's in his mid-forties, very fit looking and quite active, and was prior to his doctor's advice about permanently changing his diet, too.
