“There’s pretty good data that you can get people to decrease their alcohol consumption with brief motivational information,” she said. What’s more, the combination of drinking and smoking might indirectly increase the risk of cancer, with alcohol acting as a kind of solvent for the carcinogenic chemicals in tobacco. There are a few biological pathways that lead from alcohol consumption to a cancer diagnosis, according to the study.
The researchers estimated that, overall, about 17% of liver cancer cases and 32% of esophageal cancer cases diagnosed in 2020 were attributable to alcohol use. Smaller studies, including several conducted in Europe, have found potentially harmful drinking behaviors among both people being treated for cancer and longer-term survivors. Only a few studies have tried to capture the drinking behaviors of cancer survivors, including those still undergoing treatment, said Dr. Agurs-Collins, who was not involved in this new study. And little has been done to understand how to help those who are heavier drinkers change their behavior.

How does the combination of alcohol and tobacco affect cancer risk?
Alcoholic beverages may also contain a variety of carcinogenic contaminants that are introduced during fermentation and production, such as nitrosamines, asbestos fibers, phenols, and hydrocarbons. “We need to better understand these root causes and how best to address them,” she said. But much of the kind of work necessary to help people with substance abuse problems of any sort is beyond the realm of oncologists, he stressed. That said, Dr. DuVall continued, high alcohol use in AYAs who have or had cancer is not necessarily surprising. But results from a new study suggest that this information may not be reaching people who fall into either of these two categories.
Meeting the Mental Health Needs of Cancer Survivors
Overall, the team found that about 741,300 cancer cases in 2020, or 4.1% of the global total for that year, could be attributed to alcohol consumption. Dr. LoConte said that she has direct conversations with her patients about drinking and other behaviors that could affect their treatment. And often she directs some of that discussion to family members and loved ones who are with the patient, essentially recruiting them to help manage the patient’s drinking. Even as rates of heavy drinking have skyrocketed in the United States over the last few years, driven largely by the COVID pandemic, so has the realization that drinking has definite and serious harms, she continued.
Evidence from Western countries already strongly indicates that alcohol is a direct cause of cancer in the head, neck, oesophagus, liver, colon and breast. how do you know you got roofied But it has been difficult to establish whether alcohol directly causes cancer, or if it is linked to possible confounding factors (such as smoking and diet) that could generate biased results. It was also unclear whether alcohol is linked to other types of cancer, including lung and stomach cancers. If findings of alcohol’s impact on cancer risk have yet to deter many people from drinking, it may be because most people aren’t aware of them. According to the American Cancer Society, less than half of the American public recognizes that alcohol is a carcinogen (cancer-causing substance).
Epidemiology and pattern of alcohol use in India
Evidence of such how to stop drinking out of boredom benefits – that drinking red wine, for example, protects against heart disease – was always tenuous and has been weakened further by recent research. The supposed heart-protective effects of red wine were based on findings that moderate drinkers had better cardiovascular health than non-drinkers and heavy drinkers. But those studies categorized people who had stopped drinking because of addiction or illness as non-drinkers. As a result, the non-drinking group looked relatively unhealthy compared to others.
And because of the study’s nature, it can also create certain “biases” in the data that may affect its accuracy or how relevant it is to the larger population of people with cancer and long-term survivors. The results remained the same when the data were adjusted for other cancer risk factors, such as smoking, diet, physical activity, body mass and family history of cancer. Researchers and health professionals can do more to help break down these misconceptions, Dr. LoConte added. “We need to really make sure that we reinforce the message that all alcohol increases cancer risk,” she said.
Educating the public about the cancer risk from drinking alcohol, regardless of the beverage type, is especially urgent given the increase in drinking during the COVID-19 pandemic, Dr. Klein said. Participants in the survey are a nationally representative sample of adults aged 18 and older. The nearly 4,000 people who took part in the survey were asked how much does drinking several types of alcohol (wine, beer, and liquor) affect the risk of getting cancer. Because cancer risk increases with the amount of ethanol consumed, all alcoholic beverages pose a risk. Numerous changes need to be made to raise public awareness of the fact that drinking alcohol raises the risk of several types of cancer.
- This superactive ADH enzyme speeds the conversion of alcohol (ethanol) to toxic acetaldehyde.
- However, researchers have found no association between moderate consumption of red wine and the risk of developing prostate cancer (32) or colorectal cancer (33).
- Public health campaigns about the cancer risk posed by alcohol in England and Australia have been effective at raising awareness with their target audiences.
- “A lot of our surveys just estimate the total number of drinks per week and haven’t differentiated between the person who has one drink a day each week and someone who has 7 drinks just one day a week,” he said.
- The WHO researchers also created an interactive website where people can explore the results by country, cancer site, and other variables.
Among people of Japanese descent, those who have this form of ADH have a higher risk of pancreatic cancer than those with the more common form of ADH (30). These amounts are used by public health experts in developing health guidelines about alcohol consumption and to provide a way for people to compare the amounts of alcohol they consume. However, they may not reflect the typical serving sizes people may encounter in daily life.
Binge drinking—consuming five or more drinks within a few hours for men or four for women—is also likely more dangerous than any other type of drinking, Dr. Abnet explained. But studies have only begun to look at the associations between binge drinking and cancer, he added. The study had several limitations, including that it only looked at current alcohol consumption, not past drinking habits, said Dr. Abnet. Surveys worldwide often have not collected information about past alcohol use, “but for a lot of people, there’s a pattern where they drink more heavily when they’re young and moderately as they get older,” he explained. Breast cancer in women came in third place for number of cases, with almost 100,000 cases (about 4% worldwide) attributable to alcohol use.
Studying the Impact of Total Diet on Cancer Risk
For example, one way the body metabolizes alcohol is through the activity of an enzyme called alcohol dehydrogenase, or ADH, which converts ethanol into the carcinogenic metabolite acetaldehyde, mainly in the liver. Recent evidence suggests that acetaldehyde production also occurs in the oral cavity and may be influenced by factors such as the oral microbiome (28, 29). There is a strong scientific consensus that alcohol drinking can cause several types of cancer (1, 2). In its Report on Carcinogens, the National Toxicology Program of the US Department of Health and Human Services lists consumption of alcoholic beverages as a known human carcinogen. There likely are additional cancers linked to drinking alcohol, Dr. Orlow says, but more well-designed studies (epidemiological and other) are needed to prove that alcohol is a contributing risk factor.
A study19 from the northeast region of India has suggested that alcohol and tobacco act as important risk factors in the causation of head and neck cancer. A growing body of research points to a connection between alcohol consumption and elevated cancer risk. While any amount of alcohol can raise one’s risk of developing these cancers, the more one drinks, the higher the risk.
Alcohol consumption increases oestrogen levels by altering the hepatic redox state leading to reduced steroid degradation. In addition, chronic alcohol consumption leads to an increase in aromatase activity in peripheral tissues causing increased conversion of androgens to oestrogen17. Oestrogen is known to have proliferative effects on breast tissue and excess exposure to oestrogen is known to promote tumour growth17. Ethanol also has immunomodulatory properties and evidence suggests that it may modify innate immune responses by affecting antigen recognition and intracellular signalling18.
The biggest such wins would likely come from helping heavy drinkers cut back or quit, she added. “It’s pretty clear there are liberty cap lookalikes no health benefits [from heavy drinking], and there’s lots of risk to health overall,” she said. Approximately 4% of cancers diagnosed worldwide in 2020 can be attributed to alcohol consumption, according to a new WHO report.
For the study, the research team identified 15,199 participants who, between May 2018 and January 2022, reported a history of cancer on their initial survey. The significantly greater risks seen in men carrying the low-alcohol tolerability ALDH2 gene variant who still drank regularly suggests that greater accumulation of acetaldehyde may directly increase cancer risk. Even small amounts of alcohol can irritate mouth sores caused by some cancer treatments, including chemotherapy. Alcohol can also interact with certain cancer drugs, potentially raising the risk of harmful side effects. Alcohol use while receiving cancer therapy can be especially taxing on the liver, burdening it with removing the toxic compounds in alcohol as well as in cancer drugs. She notes that the growing number and variety of non-alcoholic beverages can be an option for people who want to stop or cut back on drinking.
