On WHO carcinogenicity---note that their "probable human carcinogens" include Red meat, Hot mate, Emission from household combustion of wood, etc. That doesn't mean the list is meaningless. They just say those are "probable" carcinogens in the literal sense, based on limited evidence on humans and sufficient evidence on experimental animals. It may be wise to avoid exposure to them more than necessary, but you don't want to take the list as if they're deadly chemicals or something.
