## TL;DR

Alcohol causes at least seven cancers and there is no safe threshold. Price, availability and cancer warning labels are the tools that work; most people still do not know alcohol causes cancer.

## Summary

Alcohol is an IARC Group 1 carcinogen causally linked to cancers of the mouth, pharynx, larynx, oesophagus (squamous), liver, colorectum and female breast; the 2020 global estimate attributed about 741,000 new cancers (4% of all) to alcohol, with a measurable share from light and moderate drinking. Risk is dose-dependent with no threshold for breast cancer. Population interventions with the best evidence are minimum unit pricing (Scotland 2018: alcohol-specific deaths fell about 13%), taxation, restrictions on availability and marketing, and labelling. Ireland's mandatory cancer warning on alcohol labels (legislated 2023, implementation deferred to 2028) and the 2025 US Surgeon General's advisory calling for cancer warnings mark a shift, opposed by industry. Awareness that alcohol causes cancer remains below 50% in most surveys. After a cancer diagnosis, continued drinking is associated with second primaries in head and neck cancer and possibly recurrence in breast cancer, but reduction trials in survivors are few.

## Fields

- Kind: Technology
- Status: established
- Last checked: 2026-09-08
- Principle: Ethanol and its metabolite acetaldehyde are genotoxic, raise oestrogen levels, and act as a solvent for other carcinogens (especially tobacco); population-level price and availability policies reduce consumption more reliably than individual advice.
- Strengths: Causal evidence is settled; Pricing and taxation have robust quasi-experimental evidence; Labelling is cheap and reaches everyone
- Limitations: Industry lobbying and trade-law challenges; Low public awareness; Little trial evidence for reduction after diagnosis
