Participants in the study will be monitored closely on a regular basis to avoid any serious risk. Overexpression of HER2 or other abnormalities may signal breast cancer cells to keep growing and certain HER2-Directed treatments are effective against this type of mBC. HER2 (Human Epidermal Growth Factor Receptor 2) is a cell surface receptor on breast cancer cells. Metastatic Breast Cancer is a type of cancer that affects the breast and has spread (metastasized) to other organs in the body. “We cannot talk about a so-called safe level of alcohol use. However, this risk is influenced by synergistic interactions with other environmental carcinogens and lifestyle factors.
Ultimately, a randomized control study with humans is what we need to conclusively prove a causal link between alcohol consumption and cancer. It should be noted that there hasn’t been a study where some people have been randomly assigned to drink one alcoholic beverage a day and other people have been assigned to drink no alcohol at all, with all followed over time. What does this mean for people who drink alcohol and for the public at large? With advisories reserved for public health challenges that require immediate action, the move offered a clear signal of the surgeon general’s interest in changing behavior around alcohol consumption.
With the exceptions of cancers of the ovary, prostate, and bladder, significant heterogeneity across studies existed for each type of cancer; this means that results vary greatly among the various studies analyzed, so an overall summary of average effect across studies must be taken with caution. Such models can identify trends (e.g., J- or U-shaped curves) as well as other relationships between alcohol exposure levels and relative risks. 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. For example, light-to-moderate alcohol consumption1 may protect against certain types of heart disease and stroke.
But awareness of the risk from drinking wine was similar in both those who had and hadn’t sought cancer information. Nevertheless, the research team also asked participants about the purported heart health benefits of alcohol, to see if it was related to their awareness about alcohol and cancer risk. There have been decades of public education campaigns about the health risks of tobacco, warning labels on tobacco products, and smokefree laws.
How Does Alcohol Increase Cancer Risk?
“The enzyme that metabolizes alcohol is lower in some ethnic groups than others, so acetaldehyde, the carcinogen in alcohol, is higher in these people,” Jani said. “We know that even small amounts of alcohol can affect the breast tissue,” Figueiredo said. “The carcinogenic effect probably isn’t affecting you right away in your younger age, but as you continue to drink as you age, this carcinogen has an accumulative effect on the body,” Jani said. In men in this age group, alcohol-related cancer deaths rose by more than 1% every year between 2007 and 2021. Utah remained the state with the lowest alcohol-related cancer deaths.
In both groups, deaths among people living in New Mexico rose the most — nearly 60% for men and 18% for women. Once in the body, alcohol breaks down into acetaldehyde — a carcinogen also found in tobacco smoke. The increase was driven by deaths in men 55 and older, the study authors said.
- The increased risk of cancer among heavy drinkers is primarily attributed to the alcohol (chemically referred to as ethanol) in alcoholic beverages.
- Researchers and health professionals can do more to help break down these misconceptions, Dr. LoConte added.
- Accordingly, one must determine whether moderate alcohol consumption results in an overall favorable or unfavorable risk-benefit balance for the individual drinker or an entire population.
- For example, light-to-moderate alcohol consumption1 may protect against certain types of heart disease and stroke.
- Even if there were some health benefit to drinking, experts said, it would be offset by the risks.
The association between alcohol and cancer is well established, and many doctors have long called on the federal government to make the connection clearer to the public. In the United States, a standard drink frequently is defined as 0.5 ounces (oz) or 14 grams of pure alcohol. Relationship between increasing amounts of alcohol and risk (i.e., relative risk or RR) for 14 types of cancer. Accordingly, the cessation or moderation of tobacco and/or alcohol use could avoid the majority of these cancer cases.
A person’s risk of alcohol-related cancers is influenced by that person’s genes, specifically the genes that encode enzymes involved in metabolizing (breaking down) alcohol (27). However, for cancers of the bladder, ovary, and uterus, either no association with alcohol use has been found or the evidence for an association is inconsistent. The federal government’s Dietary Guidelines for Americans, 2020–2025 does not recommend that individuals who do not drink alcohol start drinking for any reason.
Is it safe for someone to drink alcohol while undergoing cancer treatment?
Communities can create social and physical environments that support people in drinking less alcohol. Drinking less alcohol is better for your health than drinking more. According to MSK biologist Irene Orlow, DSc, MS, the mechanisms increasing cancer risks from alcohol are not fully understood. The researchers cited the change in public perceptions and tighter Alcohol and Lung Disease regulations for tobacco, which show the importance of public health campaigns and physicians explaining risks to their patients. Public health campaigns about the cancer risk posed by alcohol in England and Australia have been effective at raising awareness with their target audiences.
Methods Used for the Meta-Analysis
- These studies, which reported a total of 115,199 cases, investigated alcohol’s effects on the risk for developing cancer at a total of 19 sites in the body or at all sites combined (see the table and figure for a summary of the studies and their findings for each of those sites).
- However, researchers have found no association between moderate consumption of red wine and the risk of developing prostate cancer (33) or colorectal cancer (34).
- This recommendation is based on strong, consistent, and growing evidence that drinking alcohol increases your risk of developing a cancer.
- How doctors talk to their patients is its own area of study, and presenting information and or misinformation can have important ramifications.
- That’s one of the biggest public health successes of the past century.”
- “I don’t think you’ll ever find a doctor who will tell a patient, ‘You don’t drink at all.
Yearly cancer deaths linked to alcohol have doubled in the United States over the last three decades, rising from just under 12,000 a year in 1990 to more than 23,000 a year in 2021, new research finds. Measurement methods for alcohol use for evaluation of interventions and guideline approaches to alcohol and cancer are not complete Natural experiments concerning programs and policies related to alcohol and cancer need further evaluation Significant research gaps across the cancer control continuum remain, especially concerning how best to increase awareness and limit alcohol exposure.
This article summarizes the major findings of one such meta-analysis (Corrao et al. 1999, 2000). This approach allows researchers to detect relationships that may have been overlooked in the individual studies because of the relatively small sample size and insufficient statistical power of those individual studies. Meta-analyses are studies that pool data from several studies, thereby substantially enhancing the overall number of cases evaluated. This relationship is difficult to investigate in epidemiological studies, however, because it is more indirect.

What is a clinical trial?
Dr. Hay says doctors and public health officials need to do more to educate people about the risks from alcohol. Another study published in 2021 showed that nearly 70% of people did not even know that alcohol was a cancer risk factor. In fact, about 10% of participants believed that drinking wine actually decreases cancer risk. “All types of alcoholic beverages, including wine, increase cancer risk,” said Andrew Seidenberg, Ph.D., who led the study while he was a cancer prevention fellow at NCI. Even if there were some health benefit to drinking, experts said, it would be offset by the risks.
Is any level of drinking safe?
“For example, for melanoma, it is difficult to separate the potential effect of alcohol from sun exposure, and whether there is an interaction between the two exposures.” Alcohol directly contributes to 100,000 cancer cases and 20,000 related deaths each year, according to the U.S. surgeon general. More research is needed to understand some of the disparities seen in this study, such as with age, Dr. LoConte said.
Alcohol consumption also has been linked to cancers of the large bowel (i.e., colon and rectum) in both men and women and to breast cancer in women, although these associations have not yet been proven unequivocally. Another group of disorders that has been linked to drinking is cancer, particularly cancers of the upper airway and digestive tract (e.g., mouth, pharynx, larynx, and esophagus). In addition, a recent meta-analysis found no difference between red or white wine consumption and overall cancer risk (35).
This recommendation is based on strong, consistent, and growing evidence that drinking alcohol increases your risk of developing a cancer. Vivek Murthy, M.D., has called for updating the warning labels on alcohol to include increased risks of at least 7 types of common cancers, including breast, colon and liver. Seidenberg, Klein, and their colleagues found 65% of people surveyed would support adding more information about health risks to labels on alcohol containers, and those who were aware of the cancer risk were more likely to support additional labeling. People who said they had searched for cancer information were more likely to know about the cancer risks the stages of alcoholism explained early, middle and end-stage posed by drinking beer and by drinking liquor than those who did not. 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.
Sufficient evidence found for lowered risk of oral and esophageal cancer Learn how to lower your cancer risk and what CDC is doing to prevent and control cancer. Doctors can ask adult patients about their alcohol use and offer behavioral counseling to those who drink excessively. If you have had cancer treatment, CDC’s Talk to Someone simulation explains how alcohol can affect your health. Talk with Sneeze after alcohol your doctor if you have concerns about your drinking.
Numerous changes need to be made to raise public awareness of the fact that drinking alcohol raises the risk of several types of cancer. Given that, Carr said, people should be as worried about the health risks of drinking as they are about smoking. Doctors on Friday applauded a new report from the U.S. surgeon general that highlights links between alcohol consumption and seven types of cancer and suggests that alcoholic drinks should come with cancer warning labels. Consequently, any definite risk-benefit assessment for moderate alcohol drinking requires much more far-reaching analyses that are beyond the scope of this article but that in the future may provide important information from a public health perspective. For example, the analysis was unable to identify a threshold level of alcohol consumption below which no increased risk for cancer is evident. The association between various levels of alcohol consumption and an increased risk of liver cancer remains difficult to interpret even with the pooled data used in this meta-analysis.
