Even light drinking increases cancer risk
Just one alcoholic drink a day may increase the risk of cancer, according to a new study, which estimates that light drinking is responsible for 34,000 deaths a year worldwide.
New research based on more than 150,000 men and women shows that light drinking increases the likelihood of cancer of the mouth, pharynx, oesophagus and breast.
One drink a day increased the risk of cancer of the oesophagus by almost a third, according to the study being reported in the Annals of Oncology, which analysed data from more than 200 research projects. Low alcohol intake increased the risk of oral cavity and pharynx cancer by 17 per cent, and breast cancer in women by 5 per cent.
“Alcohol increases the risk of cancer even at low doses,” say the researchers. “Given the high proportion of light drinkers in the population, and the high prevalence of these tumours, especially of breast cancer, even small increases in cancer risk are of great public health relevance.”
