The Link Between Drinking and Cancer

relationship between alcohol consumption and cancer

Many people give alcohol a "health halo" because of its association with lower heart . However, the association between alcohol drinking and cancer risk is. "However, the link between increased alcohol consumption and cancer has been firmly established," Johnson said. [10 Do's and Don'ts to. Most people know that drinking too much alcohol can lead to health problems. Drinking alcohol is linked to a higher risk of mouth and throat cancers, liver cancer, colorectal cancer, and breast cancer. The American Cancer Society recommends limiting alcohol to no more than 1 drink.

For example, a meta-analysis of 87 studies shows a J-shaped curve for alcohol consumption and all-cause mortality. People who consumed 1.

In another analysis, however, although the reduction in cardiovascular mortality was smaller when active drinkers were compared with lifetime abstainers instead of all nondrinkers, some reduction was still apparent. This could mean that cancer risk associated with low levels of alcohol consumption is overstated, essentially representing risk of higher intake.

Several mechanisms may account for alcohol's role in cancer development. Alcohol also may act as a solvent, increasing other carcinogens' ability to damage cells. It's possible that genetic predisposition may increase cancer risk from alcohol. People with specific variations in the gene encoding the enzyme responsible for breaking down the acetaldehyde generated from alcohol accumulate higher levels of acetaldehyde, amplifying its carcinogenic potential.

This could lead to greater susceptibility to alcohol-induced cancer for these individuals, but more research is needed. For women, moderation is defined as up to one standard alcoholic drink per day, and for men, up to two.

When working with individual clients or patients, it's important to ask about the particular alcoholic beverages they choose when discussing moderate alcohol consumption. Craft beers are becoming increasingly popular, however, and often contain 6.

For these beers, one serving isn't 12 oz, but 9 oz or less. Likewise, for people who choose proof liquor, one serving equivalent isn't 1.

As glass sizes have increased, many people are unaware that what seems like one drink is substantially more. However, to oz wineglasses have now become standard in many restaurants and homes.

Especially if people fill these glasses beyond the traditional one-third to one-half point, "one glass" of wine can be two or more standard servings of alcohol. Likewise, people who drink cocktails that include more than one shot of alcohol may consider it "one drink," even though alcohol content is at least double that. Beers poured on tap often are served in pint glasses, which may make 16 oz, rather than 12 oz, seem like "one beer.

The same amount of alcohol poses more risk for women because differences in alcohol metabolizing enzymes and total body water make alcohol more concentrated in the blood and is more slowly eliminated than in men. Some sources talk about wine as a more healthful choice of alcohol and suggest that the phytochemical called reservatrol in red wine may be protective.

However, the association between alcohol drinking and cancer risk is consistent, regardless of whether it's beer, wine, or distilled liquor. And among wine drinkers, risk doesn't vary by choice of red, white, or a mixture. Although alcohol is a well-established risk factor for the development of certain cancers, it's unclear how postdiagnosis alcohol use affects cancer treatment and long-term survival.

However, limited data from controlled trials don't support a benefit for appetite or weight stability in advanced cancer.

Common Ground Bottom Line Alcohol poses greatest cancer risk with long-term heavy consumption. But there's some risk with intake defined as moderate, and some cancer risk even at low levels of consumption.

Accessed February 10, National survey reveals most Americans are unaware of key cancer risk factors. American Society of Clinical Oncology website. Published October 24, European Code Against Cancer 4th edition: Alcohol consumption and site-specific cancer risk: Continuous Update Project report: What sets the new study apart, said lead study author Andrew Kunzmann, a postdoctoral research fellow at Queen's University Belfast in Ireland, is that previous studies have tended to look at cancer and mortality separately.

Most existing evidence suggests that light-to-moderate drinkers had the lowest risk of dying from various causes during the study period, yet "never drinkers" had the lowest risk of developing cancer, he said.

And those who had no drinks or more than one drink a day were more at risk for death or cancers, most commonly esophageal and liver cancer and cancers of the head or neck regions, Kunzmann said. In the study, the team analyzed data about lifetime alcohol use from questionnaires that were given to the nearlyparticipants in the United States between and The questionnaires were given at the beginning of the study and asked how many drinks a person had a week at present and with what frequency over the previous year.

The researchers also looked at data on the number of primary cancer diagnoses meaning it was the first time the person had been diagnosed with cancer and deaths that occurred in the cohort over the next nine years.

That means that "we're not really reflecting what happens in younger people if they drink," he said. Also, it's difficult to account for other lifestyle factors that could have affected the results. But the results did take into consideration differences in diet, smoking and education among participants, Kunzmann noted. In general, most people agree that "if you drink alcohol, drinking less reduces your risk" of health problems, including cancer," said Dr.
