Heavy and consistent alcohol consumption significantly increases the risk of colorectal cancer, according to a new study involving over 88,000 U.S. adults.
Heavy drinking over a lifetime is linked to an elevated risk of colorectal cancer, according to a study published in the journal *Cancer* by the American Cancer Society (ACS). The research analyzed two decades of data from more than 88,000 U.S. adults to assess how long-term alcohol consumption affects the likelihood of developing colorectal cancer (CRC) or precancerous colorectal adenomas, commonly known as polyps.
Participants in the study reported their average weekly intake of beer, wine, and liquor during four distinct age periods: 18 to 24, 25 to 39, 40 to 54, and 55 and older. The study categorized “heavy drinkers” as those consuming more than 14 drinks per week, while “moderate drinkers” were defined as those having between seven and 14 drinks weekly.
The observational research found a strong correlation between consistent heavy drinking throughout adulthood and an increased risk of colorectal cancer, particularly rectal cancer. Specifically, heavy lifetime drinking was associated with a 25% higher overall risk of CRC and nearly double the risk of rectal cancer. In contrast, moderate drinking was linked to a lower overall CRC risk. When compared to light drinkers, those who consistently engaged in heavy drinking had an approximately 91% higher risk of developing CRC.
Regarding colorectal adenomas, the study did not find a significant pattern linking higher current lifetime drinking to these precancerous polyps. However, former drinkers exhibited a notably lower risk of non-advanced adenomas compared to current light drinkers.
Out of the 88,092 participants, 1,679 were diagnosed with colorectal cancer during the study period. The authors acknowledged limitations in their research, noting that it was observational rather than based on a clinical trial, and relied on self-reported alcohol consumption.
The findings suggest that consistently heavy alcohol intake and higher average lifetime consumption may elevate CRC risk, while cessation of drinking could reduce the risk of adenomas. The researchers also indicated that the associations might vary depending on the tumor site.
The connection between alcohol consumption and cancer is not a new revelation. In a recent episode of *The Dr. Mark Hyman Show*, Dr. Mark Hyman, chief medical officer of Function Health in California, discussed how even moderate drinking can adversely affect nearly every organ system in the body. He attributed this to metabolic stress, inflammation, impaired detoxification, and hormonal disruptions caused by alcohol.
Dr. Hyman emphasized that drinking increases the risk of various cancers, metabolic dysfunction, disturbances in the gut microbiome, and mitochondrial toxins. He stated, “Bottom line, alcohol taxes every major system in your body, especially your liver, your brain, your gut, and your hormones.”
In a previous interview with Fox News Digital, Dr. Pinchieh Chiang, a clinician at Circle Medical in San Francisco, noted that taking extended breaks from alcohol can lead to profound health improvements. “Over months to a year, we see sustained improvements in blood pressure, liver function, and inflammation,” she said. “Those changes directly affect long-term heart disease and stroke risk.” Dr. Chiang added that reducing or eliminating alcohol consumption over time lowers the risk of several cancers, including breast and colorectal cancer.
As the research continues to unfold, it is clear that the implications of alcohol consumption on health, particularly regarding cancer risk, warrant further attention and consideration.
These findings underscore the importance of understanding the long-term effects of alcohol consumption on health and the potential benefits of moderation or abstinence. For those concerned about their drinking habits, consulting healthcare professionals can provide valuable insights and guidance.
