Almost every tribe has a unique way of preparing alcoholic beverages using locally available plant components as starter cultures9. The prevalence of alcohol use is high in the age group of yr in the northeastern States. Mizoram and Meghalaya have reported a higher prevalence of alcohol use in comparison to other northeastern States as per the fourth round of district-level household survey10. Following epidemiological evidence of the link between alcohol use and risk of cancer at multiple sites, several pathways have been investigated to explain the carcinogenic effects of alcohol.
Alcohol is the third biggest controllable risk factor for the disease, after tobacco smoking and excess weight. For people being treated for cancer, regularly consuming a few beers or cocktails also has other potentially harmful consequences, including making their treatments less effective. And for longer-term cancer survivors, there is some evidence that regular alcohol use may increase the chances of their cancer returning.
- Drinking alcohol even at lower levels of intake can increase the risk of cancer and we previously estimated that over 100,000 cases of cancer in 2020 were caused by light and moderate drinking of the equivalent of around one or two alcoholic drinks per day [1].
- However, some individuals with the defective form of ALDH2 can become tolerant to the unpleasant effects of acetaldehyde and consume large amounts of alcohol.
- Alcohol and its byproducts can also damage the liver, leading to inflammation and scarring (cirrhosis).
- Further understanding of the carcinogenic properties of alcohol and its metabolites will inform future research, but there is already a need for comprehensive alcohol control and cancer prevention strategies to reduce the burden of cancer attributable to alcohol.
Esophageal cancer was not included because the association with alcohol drinking is confined largely to squamous cell carcinoma, whereas most cases of esophageal cancer were adenocarcinoma in the US. 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. According to the federal https://sober-home.org/ government’s Dietary Guidelines for Americans, 2020–2025, individuals who do not drink alcohol should not start drinking for any reason. The Dietary Guidelines also recommends that people who drink alcohol do so in moderation by limiting consumption to 2 drinks or less in a day for men and 1 drink or less in a day for women. 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.
People who choose to drink alcohol should limit their intake to no more than 2 drinks per day for men and 1 drink a day for women. In pregnant women, alcohol use, especially heavy drinking, may lead to birth defects or other problems with the fetus. Alcohol probably also increases the risk of cancer of the stomach, and might affect the risk of some other cancers as well. And although people who identified as Hispanic were less likely than White participants to report drinking alcohol, those who did drink were more likely to drink heavily.
How alcohol causes cancer
Similar to a prior study using a nationally representative survey,20 we found that most cancer survivors were current drinkers, and non-Hispanic White individuals or ever smokers were more likely to be current drinkers. In addition, we found that survivors with alcohol-related cancers or without self-reported current treatment were more likely to be current drinkers. Also in line with the previous study,20 we found that, among current drinkers, survivors who were younger, men, Hispanic, and ever smokers were more likely to exceed moderate drinking or binge drink.
Microbiota in the oral cavity metabolise ethanol to acetaldehyde by the enzyme catalase. However, these bacteria have limited capacity to break acetaldehyde down further into its non-harmful compound acetate, thus the oral epithelia are further exposed to acetaldehyde [21,44]. Acetaldehyde concentrations in the saliva of drinkers are between 10 and 100 times higher than in the blood; this is further doubled in smokers who drink alcohol as tobacco smoke contains high levels of acetaldehyde [21]. Retinoids are important regulators against carcinogenesis as they can induce cell growth, cell differentiation, and apoptosis [31].

All participants provided written informed consent to share EHRs, surveys, and other study data with qualified investigators for broad-based research. This study followed the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) reporting guideline. The mechanisms by which alcohol consumption may decrease the risks of some cancers are not understood and may be indirect. It doesn’t matter how much you drink – the risk to the drinker’s health starts from the first drop of any alcoholic beverage.
We treat every type of cancer, including the most important one: yours.
Using validated AUDIT-C scores that incorporate frequency of drinking, quantity of drinking, and binge drinking, we reported for the first time, to our knowledge, that 38.3% of cancer survivors in this diverse US cohort engaged in hazardous drinking. Although more studies are warranted, the high prevalence of cancer survivors engaged in hazardous drinking highlights the need for immediate interventions to reduce alcohol intake among US cancer survivors. The association between alcohol drinking and risk of other cancer types has been studied but without sufficient evidence to be classified in the IARC monographs or WCRF Continuous Update Project. Positive associations have been reported in some meta-analyses; for example, a 3% increase in lung cancer risk was observed per 10 g alcohol per day in the WCRF meta-analysis based on 28 studies (RR 1.03 (95% CI 1.01–1.04)) after excluding studies which did not control for smoking [7]. A positive association with lung cancer was only found for heavy drinkers in Bagnardi and colleagues’ meta-analysis, but this was probably due to residual confounding from smoking because alcohol use did not increase the risk of lung cancer among non-smokers [8].
Elevated concentrations of oestrogen due to alcohol use may lead to increased transcriptional activity of ER (up to 15 times higher than normal activity), resulting in proliferation of ER+ cells [39]. In addition to its involvement in downstream ROS-producing pathways, cold turkey crack it is hypothesised that IL-8 contributes to further accumulation of white blood cells (neutrophils, specifically) in the liver leading to acute inflammation. Elevated IL-8 levels have been found in patients with acute liver injury such as alcoholic hepatitis [34].
However, the federal government retained power to regulate alcohol through control of foreign and inter-state commerce, federal taxes, federal property, and financial incentives. Despite substantial epidemiological and mechanistic evidence on alcohol and cancer, several knowledge gaps remain that if filled could improve estimates of the burden of alcohol-attributable cancers, and inform tailord interventions to reduce consumption. It’s the first time, Rumgay says, that research has quantified the risks of different levels of drinking.
