Study Confirms the Cancer Prevention Benefits of Dry January and Reducing Alcohol Consumption
A recent study published in The New England Journal of Medicine has shed light on the significant impact alcohol has on cancer risk, emphasizing the benefits of cutting back, as well as avoiding it completely. The study revealed compelling evidence that reducing or eliminating alcohol intake can substantially decrease the risk of developing certain types of cancer.
The study’s findings, published late last year, are timely as many embark on Dry January, a New Year’s resolution committing to 31 days of sobriety. The results provide valuable insights into the potential health benefits of reducing alcohol consumption in the long term and abstaining.
What Does the Latest Research Say About Alcohol and Cancer Risk?
The latest research shows that reducing or eliminating alcohol consumption may lower the risk of several types of cancer, with greater benefits associated with drinking less over time.
Alcohol use is the third leading modifiable factor that increases cancer risk after cigarette smoking and excess body weight. The less alcohol you drink, the lower your risk for cancer.
The report highlights that even a single glass of alcohol per week can increase the risk for at least six types of cancer:
- Oral cancer
- Esophageal cancer
- Colorectal cancer
- Stomach cancer
- Breast cancer
- Liver cancer
The research found that stopping alcohol consumption for five to nine years was shown to reduce oral cancer risk by 34%.
The study also revealed that reducing or eliminating alcohol intake was linked to a 15% to 65% relative risk reduction for esophageal cancer, depending on the duration of cessation. However, to conclude whether the same risk reduction applies to other cancer types like colorectal, breast, and liver, researchers say more data is needed.
Why Does Alcohol Increase Cancer Risk?
Alcohol is a known carcinogen, and research continues to show that drinking alcohol increases the risk of developing several types of cancer.
Sylvia Crowder, PhD, a nutrition researcher in Moffitt Cancer Center’s Health Outcomes and Behavior Program, emphasized that there is no safe amount of alcohol consumption as alcohol is a known carcinogen. Research already suggests that cancer treatment outcomes may be poorer for patients who consume alcohol excessively.
Sylvia Crowder, PhD, a nutrition researcher in Moffitt Cancer Center’s Health Outcomes and Behavior Program, explained, “The link between alcohol consumption and cancer can’t be overlooked. Alcohol use is the third leading modifiable factor that increases cancer risk after cigarette smoking and excess body weight. The less alcohol you drink, the lower your risk for cancer.”
How Can Dry January Support Long-Term Health?
Participating in Dry January can be a meaningful first step toward reducing alcohol consumption and building healthier habits that may lower cancer risk over time.
As more individuals embrace resolutions like Dry January, the study’s findings serve as a reminder of the potential health advantages associated with minimizing alcohol consumption.
Sylvia Crowder, PhD, added, “Embracing resolutions like Dry January is a great start for anyone looking to continue healthier habits throughout the year.”
Benefits of Participating in Dry January
Reducing or eliminating alcohol consumption may provide several health benefits beyond the month of January, including:
- Decreased cancer risk, including oral, esophageal, colorectal, breast, stomach, and liver cancer
- Improved outcomes for patients with cancer or those who are in remission
- Better immunity because alcohol consumption can suppress immune function
- Improved sleep and higher energy levels
- Potential weight loss, which decreases your risk of other cancers and comorbidities
While Dry January lasts just one month, the habits developed during that time may encourage longer-term reductions in alcohol consumption. For people who choose to continue drinking, reducing the amount and frequency of alcohol intake may still provide meaningful health benefits. As research continues to examine the relationship between alcohol and cancer, current evidence supports limiting alcohol consumption as one way to help reduce cancer risk and support overall health.
