Alcohol Cancer Deaths: How Drinking Increases Cancer Risk and Mortality (2026)
Alcohol cancer deaths are an important global public-health concern. Scientific evidence shows that alcohol consumption can increase the risk of several types of cancer, including breast, liver, colorectal, mouth, throat, laryngeal, and esophageal cancers.
Alcohol is recognized as a carcinogenic exposure, and the risk generally increases with greater alcohol consumption. Understanding the connection between alcohol and cancer can help people make informed decisions about their health.
What Are Alcohol-Related Cancer Deaths?
Alcohol-related cancer deaths refer to deaths from cancers in which alcohol consumption contributed to the development of the disease.
Alcohol does not mean that every person who drinks will develop cancer. Cancer usually develops through multiple factors, including genetics, age, tobacco use, body weight, diet, environmental exposures, and lifestyle.
However, alcohol is an established and potentially preventable risk factor for several cancers.
Does Alcohol Cause Cancer?
Yes. Alcohol consumption is classified as a carcinogenic exposure by the International Agency for Research on Cancer (IARC).
Strong evidence links alcohol consumption with several cancers, including breast, liver, colorectal, mouth, throat, laryngeal, and esophageal cancers.
The cancer risk is related to ethanol and its metabolites rather than whether the alcoholic drink is beer, wine, or spirits.
How Does Alcohol Increase Cancer Risk?
Alcohol can contribute to cancer development through several biological mechanisms.
Alcohol Produces Acetaldehyde
When the body breaks down ethanol, it produces acetaldehyde. Acetaldehyde can damage DNA and interfere with normal cellular processes.
Repeated DNA damage can contribute to mutations and abnormal cell growth.
Alcohol Can Damage DNA
Alcohol metabolism can contribute to cellular damage. When DNA damage is not properly repaired, mutations may accumulate and potentially contribute to cancer development.
Alcohol Can Affect Hormones
Alcohol can influence hormone levels, including estrogen. This is particularly relevant to breast cancer risk in women.
Alcohol Can Increase Oxidative Stress
Alcohol metabolism can increase oxidative stress, which may damage cells, proteins, and DNA.
Alcohol Can Affect Nutritional Health
Heavy alcohol consumption can interfere with nutrition and the absorption or metabolism of nutrients that are important for normal cellular function.
Alcohol Can Interact With Tobacco
Alcohol and tobacco together can create a particularly concerning combination for cancers of the mouth, throat, larynx, and esophagus.
Which Cancers Are Linked to Alcohol?
Alcohol consumption is associated with several types of cancer. The table below summarizes the major cancer sites linked to alcohol.
| Cancer Type | Connection With Alcohol |
|---|---|
| Breast Cancer | Alcohol consumption increases breast cancer risk in women. |
| Liver Cancer | Long-term heavy alcohol use can cause chronic liver damage and cirrhosis, increasing liver cancer risk. |
| Colorectal Cancer | Alcohol consumption is associated with increased risk of colon and rectal cancers. |
| Mouth Cancer | Alcohol can increase the risk of cancers affecting the oral cavity. |
| Throat Cancer | Alcohol is associated with cancers of the throat and pharynx. |
| Laryngeal Cancer | Alcohol consumption is linked with cancer of the larynx or voice box. |
| Esophageal Cancer | Alcohol increases the risk of esophageal cancer, especially with long-term heavy consumption. |
Alcohol and Cancer Deaths: Key Statistics
| Measure | Key Finding |
|---|---|
| Global cancer deaths attributable to alcohol | WHO estimated approximately 401,000 deaths in 2019. |
| Major cancer sites | Breast, liver, colorectal, mouth, throat, laryngeal, and esophageal cancers. |
| Risk relationship | Cancer risk generally increases as alcohol exposure increases. |
| Prevention | Reducing or avoiding alcohol can lower alcohol-related cancer risk. |
Does Even Small Amounts of Alcohol Increase Cancer Risk?
Yes. Some cancer risks can increase even with relatively low levels of alcohol consumption.
There is no completely risk-free level of alcohol consumption in relation to cancer risk. However, this does not mean that everyone who drinks a small amount will develop cancer.
Individual risk is influenced by several factors, including:
- Amount of alcohol consumed
- Frequency of drinking
- Duration of alcohol exposure
- Age
- Genetics
- Smoking
- Body weight
- Diet
- Other health and environmental factors
Is Red Wine Safer Than Beer or Liquor?
No alcoholic beverage should be considered cancer-safe.
Beer, wine, and spirits all contain ethanol. The presence of ethanol is important when considering alcohol-related cancer risk.
Red wine has sometimes been discussed because of compounds such as resveratrol, but this does not mean that drinking wine prevents cancer.
Switching from liquor to wine does not eliminate alcohol-related cancer risk.
Alcohol and Cancer Risk in Women
Alcohol is particularly important in discussions about breast cancer.
Alcohol consumption can increase breast cancer risk, and risk generally rises with increasing alcohol exposure.
Other factors also influence breast cancer risk, including age, family history, genetics, reproductive history, body weight, and physical activity.
Alcohol and Cancer Risk in Men
Men can also develop alcohol-associated cancers, including cancers of the mouth, throat, esophagus, liver, colon and rectum, and larynx.
Individual risk depends on alcohol exposure and other factors such as smoking, age, genetics, and overall health.
Alcohol and Smoking: A Dangerous Combination
Using alcohol and tobacco together can substantially increase the risk of certain cancers.
Alcohol can make tissues in the mouth and upper digestive tract more vulnerable to tobacco-related carcinogens.
| Combination | Potential Concern |
|---|---|
| Alcohol + Smoking | Higher risk of cancers of the mouth, throat, larynx, and esophagus. |
| Heavy Alcohol Use | Greater exposure to alcohol-related carcinogenic effects and other health risks. |
| Long-Term Alcohol Use | Can contribute to chronic liver disease and other long-term health problems. |
Can Stopping Alcohol Reduce Cancer Risk?
Reducing alcohol consumption or stopping drinking can lower alcohol-related health risks.
Evidence indicates that reducing or stopping alcohol consumption can reduce the risk of developing alcohol-associated cancers.
The degree and timing of risk reduction can vary according to the cancer type, previous alcohol exposure, and other individual factors.
How to Reduce Alcohol-Related Cancer Risk
Reducing alcohol exposure is one practical way to lower alcohol-related cancer risk.
| Step | Why It Matters |
|---|---|
| Drink Less or Avoid Alcohol | Lower alcohol exposure can reduce alcohol-related cancer risk. |
| Avoid Binge Drinking | Can reduce multiple short- and long-term alcohol-related health risks. |
| Do Not Smoke | Avoiding tobacco is particularly important because alcohol and smoking can interact to increase cancer risk. |
| Maintain a Healthy Weight | Healthy weight management supports overall cancer prevention. |
| Stay Physically Active | Regular physical activity supports overall health and helps reduce the risk of several chronic diseases. |
| Follow Cancer Screening Recommendations | Appropriate screening can help detect certain cancers earlier. |
| Seek Professional Help | People struggling to reduce alcohol can receive evidence-based treatment and support. |
Cancer Warning Signs You Should Not Ignore
Drinking alcohol does not mean that a person has cancer. However, persistent or unexplained symptoms should be discussed with a healthcare professional.
- Unexplained weight loss
- Persistent difficulty swallowing
- Unexplained bleeding
- Persistent changes in bowel habits
- Persistent mouth sores
- A lump or swelling that does not go away
- Persistent abdominal discomfort
- Persistent hoarseness or voice changes
- Unexplained or persistent pain
