New genetic study confirms that alcohol is a direct cause of cancer Nuffield Department of Population Health

Moreover, most U.S. adults are unaware of the alcohol-cancer link (7), and the interrelationships of alcohol control regulations and cancer risk is unclear. Some studies show that drinking three or more alcoholic drinks per day increases the risk of stomach and pancreatic cancers. There is also evidence that drinking alcohol increases the risk for prostate cancer. All alcoholic drinks, including red and white wine, beer, and liquor, are linked with cancer. Lipotropic nutrients such as folate are key sources of the methyl groups necessary for DNA methylation and influence the availability of SAMe, which is also essential to DNA methylation [25].

  1. Too much alcohol can add extra calories to the diet, which can contribute to weight gain in some people.
  2. 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.
  3. Cells that are damaged by the alcohol may try to repair themselves, which could lead to DNA changes that can be a step toward cancer.
  4. According to a National Cancer Institute article, some people measure a standard drink by how much they can fit in a single glass.
  5. But it is not clear whether alcohol use after treatment might increase the risk of these cancers coming back (recurring).

Alcohol intake may deplete folate levels, or indeed be a cause of folate and B vitamin deficiency if alcohol constitutes the majority of calories consumed, as observed in malnourished alcoholics [21,26]. Folate deficiency affects the availability of nucleotides needed for DNA synthesis leading to accumulation of deoxyuridine monophosphate which is incorporated into new DNA molecules causing after-work drinking double-strand breaks and chromosomal damage [25]. Interestingly, there is evidence that higher folate intake among alcohol drinkers may attenuate the increased risk of liver cancer mortality compared with those with low folate intake [36]. This attenuation was also observed for risk of postmenopausal breast cancer among women who drink alcohol and have higher folate levels [37].

Meeting the Mental Health Needs of Cancer Survivors

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. That might mean teaching doctors around the world to talk about alcohol use as a possible cause when a patient complains of sleep or memory problems or when they have the beginning signs of liver disease. “You tailor the information to the personal concerns of the patient in front of you,” says Justice. The first mutation is a loss-of-function mutation in the gene for the enzyme aldehyde dehydrogenase 2 (ALDH2). Both acetaldehyde and ethanol can impact DNA methylation which may lead to changes in the expression of oncogenes and tumour-suppressor genes [21]. Acetaldehyde can inhibit the activity of DNA methyltransferase (DNMT) which is essential for normal DNA methylation; acetaldehyde can also reduce DNMT mRNA levels leading to less production of DNMT [25].

Smoking Study

Launched in 2018, All of Us captures information on participants’ lifestyle and other behaviors and personal background via comprehensive surveys. Participants can also allow access to their electronic health records (with all identifying information removed), providing important insights on treatments received and other relevant health information. But the All of Us study, Dr. Cao and her colleagues explained, offered a unique opportunity ketamine effects of ketamine to take a robust look at people in these groups in the United States. But results from a new study suggest that this information may not be reaching people who fall into either of these two categories. Those strategies could include increasing taxes on alcohol and adding cancer warning labels to alcohol similar to warnings now on cigarette packages. Drinking rates are relatively low in parts of Africa, but that seems to be changing.

Alcohol and cancer: Identifying evidence gaps and research challenges across the cancer continuum

“People my age are way more accepting of it,” said Tessa Weber, 28, of Austin, Texas. She stopped drinking for Dry January this year because she’d noticed alcohol was increasing her anxiety. Moderate drinking was once thought to have benefits for the heart, but better research methods have thrown cold water on that.

US adults beliefs about whether wine, beer, and liquor consumption is linked with cancer. There have been decades of public education campaigns about the health risks of tobacco, warning labels on tobacco products, and smokefree laws. 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. More research is needed to better understand alcohol use among people with cancer, the study team wrote.

People who report drinking moderately tend to have higher levels of education, higher incomes and better access to health care, Naimi said. The reduction in cell viability was more pronounced in undifferentiated cells as compared to differentiated cells. At the lowest tested ethanol concentration of 10 mM, alcohol exposure led to a 6-11% induction in metabolic activity in differentiated cells and 1-10% induction in undifferentiated cells. Alcohol exposure was found to reduce the metabolic activity and viability of both undifferentiated and differentiated cells in a dose- and exposure-duration-dependent manner. A significant reduction in cell viability was observed after six hours of exposure to alcohol concentrations of 20 mM or more.

In the United States alone, about 75,000 cancer cases and 19,000 cancer deaths are estimated to be linked to alcohol each year. The researchers categorized alcohol bipolar disorder and alcohol use based on responses to several alcohol-specific questions. They also used an assessment tool, called AUDIT-C, that was developed to study drinking behavior.

That idea came from imperfect studies comparing groups of people by how much they drink. And none of the studies randomly assigned people to drink or not drink, so they couldn’t prove cause and effect. This workshop brought together basic, epidemiologic, behavioral, translational, clinical, regulatory, and communication scientists to discuss evidence gaps related to the role of alcohol across the cancer continuum. Alcohol and its byproducts can also damage the liver, leading to inflammation and scarring (cirrhosis).

The lowest rates of alcohol-related cancers in the world were found in Saudi Arabia and Kuwait, where religious-based policies ensure low rates of drinking. Alcohol also reduces the body’s ability to absorb certain cancer-protective nutrients, including vitamins A, C, D, E and folate. ERs are important transcription factors within cells and may provide the main pathway by which alcohol promotes breast tumour growth [40]. 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]. As it is highly reactive towards DNA, acetaldehyde may bind to DNA to form DNA adducts which alter its physical shape and potentially block DNA synthesis and repair [21]. These DNA adducts are particularly genotoxic as they can induce DNA point mutations, double-strand breaks, sister chromatid exchanges, and structural changes to chromosomes [21,22].

Because overt behaviors appear to be more susceptible to normative influence than clandestine behaviors (44), alcohol consumption behaviors in groups might be especially subject to social sanction. Increased awareness of the alcohol-cancer link might encourage some people to warn family and friends about consumption, although the efficacy of such communication on behavior is unclear. Many individuals of East Asian descent carry a version of the gene for ADH that codes for a “superactive” form of the enzyme. This superactive ADH enzyme speeds the conversion of alcohol (ethanol) to toxic acetaldehyde.
