Alcohol and Cancer: What the Evidence Says
4 min read · All articles
Many people are surprised to learn that alcohol is a known cause of cancer. It's one of the most important — and least talked-about — reasons to drink less.
What the experts say
The International Agency for Research on Cancer classifies alcohol as a Group 1 carcinogen, the same category as tobacco smoke. The World Health Organization has stated that there is no level of alcohol consumption that is known to be safe for health.
Which cancers are linked to alcohol
Drinking is linked to at least seven types of cancer, including:
- Mouth, throat and oesophagus
- Voice box (larynx)
- Breast
- Liver
- Bowel (colorectal)
How alcohol causes harm
Your body breaks alcohol down into acetaldehyde, a chemical that can damage DNA. Alcohol can also raise levels of certain hormones such as oestrogen, and it makes it easier for other harmful substances, like those in tobacco, to be absorbed.
It's about amount, not type
Wine, beer and spirits all carry risk — what matters is how much alcohol you consume over time. The risk rises with the amount you drink, so every drink you skip lowers it.
The encouraging part
Risk falls after people reduce or stop drinking, though it takes time. Cutting back is one of the most practical steps you can take for your long-term health.
