LONDON – Alcohol directly causes at least seven types of cancer, and it is dangerous even for people who enjoy small or moderate amounts, scientists warn.

According to a new study published in the journal Addiction, there is a link between alcohol and cancer that cannot be explained by other factors. Scientists have concluded that there is sufficient credible evidence to definitively state that drinking is the direct cause of the disease, says Jennie Connor, one of the authors of the study.

– There is strong evidence that alcohol causes cancer in at least seven locations in the body, and possibly the others, said Connor.

– Even without the understanding of biological mechanisms, epidemiological evidence supports the thesis that alcohol causes cancer of the mouth, larynx, esophagus, liver, colon and breast, Connor said, adding that also alcohol causes skin cancer, prostate and pancreas.

The conclusion is a result of 10 years studying the data of World Wide Fund for Cancer Research, the International Organization for Research on Cancer and the World Health Organization.

– The greatest risk is associated with a higher intake of alcohol, no serious burden lies on those who drink small to moderate amounts, warned Connor.

According to a survey conducted by the non-profit organization Cancer Research UK, as many as nine out of ten people are not familiar with the link between alcohol and cancer.

– This research is a powerful reminder that there is a strong connection between these two things, said dr. Jana Witt, a spokeswoman for Cancer Research UK.
