DHAKA: Even light and moderate drinking - up to one drink a day for women and two drinks a day for men - could increase the risk of cancer, say researchers.
The work in the British Medical Journal looked at two large US studies involving more than 100,000 adults, reports the BBC.
According to the report, the clearest link was for breast cancer.
Experts say the findings reinforce the health message that people should limit how much they drink and have some alcohol-free days.
There is no guaranteed safe level of drinking, but if you drink within the recommended daily limits, the risks of harming your health are low, they say.
The NHS recommends that men should not regularly drink more than three to four units (two cans of 4.5% lager) a day and women two to three units (two small glasses of 12% wine) a day - although these drinking guidelines are currently under review and so could change.
In the American studies, light to moderate drinking was defined as up to 15g alcohol (a small glass of wine) per day for women and up to 30g alcohol (two 355ml bottles of beer) per day for men.
For women, the researchers observed, the risk of alcohol-related cancers - mainly breast cancer - increased even after one alcoholic drink a day.
No significant link was found in men who had never smoked, but among men who were current or ex-smokers, light or moderate drinking appeared to increase the risk of certain cancers.
