This was after they had refused bribery offers to stop being active in policymaking efforts. In one extreme case, violence against anti-smoking activists in Nigeria led to two deaths. An essential round-up of science news, opinion and analysis, delivered to your inbox every weekday.
Around half of the sources included in our study actually talked about how the targets of intimidation responded. And most of those reported fighting back by exposing the tactics, correcting misinformation and launching their own legal challenges against the perpetrators. In New Zealand, an industry-paid consultant working for tobacco, alcohol and UPF companies sent Freedom of Information Act requests to researchers and advocates and used the resulting information to denigrate them. Launched in 1943, Medicina Clínica is a fortnightly journal aimed at the promotion of clinical research and practice among internal medicine and other specialists. The key characteristics of Medicina Clínica are the scientific and methodological rigor of its manuscripts, the topicality of its contents, and, especially, its practical focus with highly useful information for clinical practice.
The authors said they “found that alcohol use causes a substantial burden of cancer,” but other experts say multiple limitations could weaken the strength of that proposed relationship. “These include quitting smoking, moderation of alcohol intake, maintaining a healthy diet and weight, staying physically active, and protecting the skin from UV radiation,” Harb detailed. “I think the perception often is, if you can fit it in a glass, it’s one drink,” Dr. LoConte said. But studies have shown that people pouring their own wine or spirits at home tend to underestimate the amount they’re actually consuming. “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 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.
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. Similarly, for esophageal cancer, the researchers zeroed in on a type called squamous cell carcinoma, which is the only type known to be triggered by alcohol consumption.
Health Conditions
Evidence from Western countries already strongly indicates that alcohol is a direct cause of cancer in the head, neck, oesophagus, liver, colon and breast. 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. The NCI workshop/webinar summary pointed out that few surveys have tried to capture information on alcohol consumption over a lifetime.
- One of the strengths of this meta-analysis is that the investigators performed a separate analysis of studies that also reported estimates adjusted for tobacco use, which contributes to various forms of cancer, prominently lung cancer.
- For example, ethanol can increase estrogen in the body, which increases the risk of breast cancer.
- Looking at evidence from the last 20 years, we identified 64 sources published between 2000 and 2021 which detailed intimidation of researchers and advocates working in the tobacco, alcohol and UPF spaces.
- Such analyses were conducted for most cancers of the upper airways and digestive tract, as well as for lung and bladder cancer.
- 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.
Researchers of tobacco, alcohol and ultra-processed foods face threats and intimidation: New study
To evaluate the overall effects of alcohol on the cancer risk of a population, one must accurately quantify its effects on various types of tumors. To this end, researchers have performed comprehensive meta-analyses of published studies investigating the relationship between alcohol intake and the risk for numerous types of cancer. Meta-analyses are studies that pool data from several studies, thereby substantially enhancing the overall number of cases evaluated. 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. This article summarizes the major findings of one such meta-analysis (Corrao et al. 1999, 2000).

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. Worldwide, alcohol may cause around 3 million deaths each year, including over 400,000 from cancer. With alcohol consumption rising, particularly in rapidly developing countries such as China, there is an urgent need to understand how alcohol affects disease risks in different populations. what drug makes you foam out the mouth Even people who had one small drink a day were about 10% more likely to die of cancer than occasional drinkers.
The age at which one begins drinking, levels of consumption, and episodes of binge drinking could potentially play a role in cancer risk, but that history is rarely available. Additionally, the study didn’t “consider the synergistic effect between alcohol and tobacco, which is reported as a true interaction for most upper aerodigestive tract cancers,” the authors wrote. The cancer estimates for 2020 might have also been impacted by the Covid-19 pandemic, which disrupted health systems and made some patients feel unsafe going to the doctor, the authors added.
We included 876 lung cancer cases and 840 controls of the CAPUA hospital-based case–control study. Further research into the mechanisms of alcohol’s effect on cancer risk could increase understanding of other factors that may interact with alcohol to increase cancer risk. The biggest such wins would likely come from helping heavy drinkers cut back or quit, she added.
Over 4% of all new cancer cases in 2020 were attributable to alcohol consumption, according to a study published Tuesday in the journal The Lancet Oncology. It is important to continue studying cancers linked to alcohol, as patterns of alcohol use continue to shift over time, Dr. Abnet said. For example, in many parts of the world, women have begun drinking more than they used to, he explained. And, he added, if drinking rises within a group, their cancer cases are eventually likely to rise as well. 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.

Bilchik commented that while the role of alcohol in cancer development is obviously important, the report does not provide sufficient information on the quantities of alcohol involved. According to the latest Cancer Progress Report, 40% of all cancer diagnoses in the U.S. are linked to modifiable risk factors. “This includes effective tobacco control, a greater awareness and uptake of cancer screening to identify many cancers earlier at a more treatable stage, and more effective treatments that can often be delivered while minimizing toxicities. While very encouraging, the rising rates of many incident cancers also indicates that there’s much more to be done,” Hawk noted. A serving of alcohol is measured by volume, but the amount of alcohol in a serving can vary greatly depending on the variety or brand of beer or wine or the type of mixed drink or cocktail—as well as how much is poured.
