Drinking a 750 ml bottle of wine a week increases the risk of developing cancer, 10 women a week and five cigarettes a week men, such a study.
The British researchers said that this is a good way to convey the health risks of moderate alcohol consumption.
But experts said that smoking is a greater cancer risk for most drinkers than alcohol.
The only way to reduce the risks of smoking was to stop completely.
The Government's Alcohol Consumption Policy recommends that men and women drink no more than 1
The guide also states that there is no "safe" level of alcohol when it comes to health risks.
This study states that moderate drinking is also possible The risk of cancer, especially breast cancer, is the most common cancer among women in the United Kingdom.
Communicating Cancer Damage
When writing in BMC Public Health, researchers calculated that 1,000 non-smoking and 1,000 men smoke Non-smoking women drank a bottle of wine every week, about 10 additional men and 14 additional women could go on during their lifetime Getting cancer.
In women, alcohol consumption was associated with an increased risk of breast cancer, and in men this was the case with cancers of the gastrointestinal tract ct and liver.
For their calculations, the University of Southampton and Bangor University research team used cancer research data from Cancer Research UK and data on the number of cancers in the population associated with tobacco and alcohol
Dr. Minouk Schoemaker, a scientist at the Institute of Cancer Research in London, who is researching the causes of breast cancer, said the study offered "interesting insights," but said the picture was not easy.
"The overall picture of cancer risk is enormously complex and differentiated, so it is important to know that this new study is subject to a number of assumptions," she said.
"For example, it is difficult to completely unravel the effects of alcohol and cigarette smoking and the study did not consider the duration of smoking or the time since quitting."

- Middle Aged Demands" Drinking Days "
The study looked only at cancer – not just any other disease, such as cardiovascular or lung disease common to smokers.
Also uses data from 2004 and did not consider other factors that could cause cancer, such as age, family genes, diet and other lifestyle aspects.
And the number of cigarettes that are "equivalent" to alcohol is low when most smokers smoke a lot more per day.
As a result, the jury talks about how useful the study is.
"Smoking More Dangerous"
Prof John Britton, director of the UK Center for Tobacco and Alcohol Studies at the University of Nottingham said "I'm not sure if many people decide whether they want to smoke or drink … based on how comparable the risks are of the two.
"This study shows that smoking is much more dangerous than alcohol consumption in terms of cancer risk, and smoking is far more dangerous than alcohol in a number of other diseases."
"When smokers worry about health, the best they do can do is give up smoking.
"People who consume alcohol should try to stay within the recommended guidelines of 14 units a week," Britton added.
But Dr. Bob Patton, a lecturer in clinical psychology at the University of Surrey, said the study could transform public opinion.
"It is likely that the results of this simple study will have a profound impact on how drinkers, and especially drinkers, consider the risks associated with alcohol consumption," he said.
"Viewing alcohol in the same light as smoking cigarettes can result in reduced consumption and associated damage."
