The Hong Kong Anti-Cancer Society is warning that only 30 percent of Hong Kong people it surveyed are aware of the cancer risks of drinking.
The NGO polled more than a thousand people. It said only two percent of respondents believed that drinking would increase the risk of breast cancer.
Six percent of the about 700 people who admitted to drinking in the past three months said they had engaged in binge drinking once a week. Binge drinking was classified as the equivalent of five glasses of table wine at one sitting.
"We know that alcohol itself is a carcinogen, it's actually a category one carcinogen, so that highlights the risk of those people who participate in binge drinking," said Dr Rico Liu, the chairman of society's cancer education subcommittee. "My worry is that a lot of those people, they do not know the linkage between drinking alcohol and cancer."
Speaking to RTHK's Iris Yeung, Dr Liu said the reason behind the survey was that drinking was common and that alcohol was causing a wide range of problems, including various cancers and liver disease.
He said the best option was not to drink alcohol but, failing that, the most important thing was to stop the frequency of binge drinking.
