Drinking a little, often, could increase your cancer risk

Embargoed until: Publicly released:
Peer-reviewed: This work was reviewed and scrutinised by relevant independent experts.

Observational study: A study in which the subject is observed to see if there is a relationship between two or more things (eg: the consumption of diet drinks and obesity). Observational studies cannot prove that one thing causes another, only that they are linked.

People: This is a study based on research using people.

It is not just heavy drinking sessions that put you at risk of cancer, with a new study showing that frequent drinking may be a more important risk factor for gastrointestinal (GI) cancers than the amount of alcohol drunk at each session. The study out of Korea found that for a given weekly amount of alcohol, the risk of GI cancer was higher if people drank more often, than if they drank more but less frequently. The authors say people should be careful with their drinking habits, including regular consumption of small amounts of alcohol.
