Approximately 4% of cancers diagnosed worldwide in 2020 can be attributed to alcohol consumption, according to a new WHO report. Similarly, synergistic effects have been reported between high alcohol consumption and dietary factors, such as low consumption of fruits and vegetables. Two readers, who received no information on the names and affiliations of the authors of each study or the alcohol-related results, independently determined the eligibility of each article for inclusion in the meta-analysis. When the results of a study were published in more than one article, only the most recent and complete article was included in the analysis. As with most questions related to a specific individual’s cancer treatment, it is best for patients to check with their health care team about whether it is safe to drink alcohol during or immediately following chemotherapy treatment.

The report authors called for increased efforts to help people make lifestyle changes that can reduce their cancer risk. About 1 in 5 cancer diagnoses are related to body weight, poor diet, alcohol use, and physical inactivity. Lifestyle awareness campaigns have been effective in the past, with declining smoking rates being linked to reduced cancer rates. We also were able to use that survey to look at the intersection of heart disease and cancer awareness. There has been some pretty accepted popular literature in the past suggesting wine is good for your heart. So, we were interested in looking at how people have been influenced by these beliefs about types of alcohol.
Alcohol and Cancer Risk
Of particular concern is the rising rates of colorectal cancer among younger people, and it is often diagnosed in life-threatening late stages. People in Generation X (born between 1965 and 1980) are predicted to have a higher rate of cancer than prior generations. Next, among 3018 participants who both completed questionnaires and underwent colonoscopy, we further analyzed whether advanced intestinal lesions, including AA and CRC, were detected more frequently in the HR tier compared to AR or MR tiers (Table 2).
Two-thirds of these were peer-reviewed sources which mentioned instances of intimidation. The majority were not papers specifically about intimidation, but most were about corporate interference in policy passage or implementation. The remaining third were sources like blogs, newspaper articles, news stories in peer-reviewed journals, a case study, a press release, a recorded seminar and a book. Our new paper, published in Health Promotion International, reveals how researchers producing evidence of the harms of these industries have been intimidated because of their work. Alcohol and polymorphisms in genes involved in the metabolism of alcohol and folate are related to the onset of lung cancer. Launched in 1943, Medicina Clínica is a fortnightly journal aimed at the promotion of clinical research and practice among internal medicine and other specialists.
How Does Alcohol Increase Cancer Risk?
Yet it’s crucial to remember that while alcohol increases cancer risk, it doesn’t mean everyone who drinks will develop cancer. In 2019, more than one in 20 cancer diagnoses in the West were attributed to alcohol consumption, and this is increasing with time. This figure challenges the widespread perception of alcohol as a harmless social lubricant and builds on several well-conducted studies linking alcohol consumption to cancer risk. On the other hand, economic growth in places like China, India and Vietnam might lead how to smoke moon rock to increased alcohol use and related cancers down the road.
Participants were asked to undertake a risk factor assessment questionnaire for information collection. The risk assessment questionnaire was conducted face-to-face by investigators who have received uniform training. There are several biological pathways by which drinking alcohol can lead to cancer development, the authors wrote, including DNA, proteins and how ethanol metabolizes and effects hormone regulation. Between 28% and 45% of East Asian people, for example, carry a variant of the ALDH2 enzyme that has been linked with a higher risk of developing cancers in the upper aerodigestive tract, the authors wrote.
Kara Wiseman is an epidemiologist and public health professor at the University of Virginia researching cancer prevention, alcohol use and smoking secession. It was also easy to ignore a steady drumbeat of studies that showed that alcohol consumption is undeniably linked to cancer risk. Cancer cases and alcohol consumption were highest in central and eastern Europe and eastern Asia, where hepatitis B is a common cause of hepatocellular carcinoma, according to the American Cancer Society.
- We have created a text-messaging program that’s being delivered to airmen who are just starting their job training in the Air Force to try and reduce binge and heavy drinking.
- “Fewer than one in three Americans recognize alcohol as a cause of cancer,” says Harriet Rumgay, researcher at the International Agency for Research on Cancer, the specialized cancer agency of the World Health Organization.
- According to the Surveillance, Epidemiology, and End Results (SEER) program, from 2012 to 2018, the 5-year survival rates of patients with early-stage and late-stage CRC were 90.9 and 15.1%, respectively.
- It can impair nutrient and vitamin absorption, alter hormone levels, and even make it easier for harmful chemicals to penetrate cells in the mouth and throat.
- Those studies, scientists say, didn’t adequately account for people who had quit drinking due to health problems.
- Heavy alcohol drinking is defined as having 4 or more drinks on any day or 8 or more drinks per week for women and 5 or more drinks on any day or 15 or more drinks per week for men.
What is the evidence that alcohol drinking can cause cancer?
The study’s authors suggest that the numbers of alcohol-related cancers are probably even higher than these estimates. “That’s because we didn’t include former drinkers in our main analysis, even though they may have an increased risk of cancer,” says Rumgay. They also looked only at cancers where the risk factor has been scientifically shown to increase with alcohol use. They didn’t include cancers for which emerging evidence suggests are likely linked to alcohol, such as pancreatic and stomach cancers. Of the 741,300 new alcohol-attributable cancer cases diagnosed last year, men represented 568,700 cases, while women accounted for 172,600 cases, the researchers found. Nearly 47% of the alcohol-attributable cancers were linked to heavy drinking, which the authors defined as 60 or more grams of ethanol alcohol (the alcohol found in alcoholic beverages), or more than six drinks, per day.
One limitation is that for most types of cancer included, the estimates of alcohol’s effects tended to vary widely among the individual studies, making interpretation of the pooled data more difficult. Part of this variability may result from differences in the characteristics of the subjects included in the studies. For example, the gender of the study participants may play a role because potential differences in alcohol breakdown (i.e., metabolism) exist between men and women and may systematically influence the overall pooled estimates (Corrao et al. 1999, 2000).
The processes that the body uses to break down alcohol produce a compound called acetaldehyde, a toxin that several organizations have classified as a probable cause of cancer in people. A person’s risk of alcohol-related cancers is influenced by their genes, specifically the genes that encode enzymes involved in metabolizing (breaking down) alcohol (27). Effective screening for colorectal cancer (CRC) enables earlier diagnosis and intervention to improve patient survival.
Statistically significant gender differences existed only for esophageal and liver cancer—where the alcohol-related risk was higher in women than in men—but not for other types of cancer. The increased risk of cancer among heavy drinkers is primarily attributed to the alcohol (chemically referred to as ethanol) in alcoholic beverages. It is still unclear, however, whether any defined consumption threshold exists below which no increased risk for cancer is evident (IARC 1988; Doll et al. 1999). Alcohol causes at least seven types of cancer, including the most common cancer types, such as bowel cancer and female breast cancer.
