You should ditch those boozy weekend nights as the rise in alcohol consumption all over the world is being blamed for a huge increase in oral cancers among 40-somethings. In the UK, for instance, oral cancer rates for women in their 40s have increased by 24 per cent since mid-1990s, and by 28 per cent for men. Cancer Research UK says three quarters of oral cancers in UK are thought to be caused by smoking and drinking alcohol. Studies show that for women, drinking just one unit a weeknight increases the risk of some common cancers. The best guideline is for people to stick to recommended guidelines for alcohol consumption – two to three units daily for women.
