Analysis in 2017 of the websites for national cancer societies in Australia, Canada, Ireland, New Zealand, the United Kingdom and the United States-including Cancer Council Australia, the Canadian Cancer Society, the Irish Cancer Society, Cancer Society New Zealand, Cancer Research UK and the American Cancer Society-shows that only the American Cancer Society and Canadian Cancer Society websites fail to state that alcohol is a group 1 carcinogen and can cause cancer at low doses, and that there is no safe threshold for cancer risk.
