Five things to know about a common habit that can impact your risk for colorectal cancer

Colorectal cancer is becoming a growing concern, especially among younger adults. According to recent reporting from Fox News, researchers and medical experts are pointing to a widespread lifestyle habit that may be increasing the risk more than many people realize: regular alcohol consumption. Knowing that alcohol and colorectal cancer risks are linked, it is important to know the signs of colorectal cancer and ways to reduce the risk of developing it. While some risk factors cannot be changed, this is one area where awareness and lifestyle choices can make a meaningful difference. Here are five key takeaways from the study to keep in mind, as noted by our team at Atlantic Gastroenterology of Brooklyn, New York.

1. Alcohol Is Classified as a Known Carcinogen.

One of the most important points from the study is that alcohol is not just a casual indulgence—it is classified as a Group 1 carcinogen. This means there is strong scientific evidence that it can cause cancer in humans.  When alcohol breaks down in the body, it turns into a toxic substance called acetaldehyde. This compound can damage DNA in cells over time, increasing the likelihood of cancer development, particularly in the gastrointestinal tract.

2. Even “Moderate” Drinking Can Increase Risk.

Many people assume that only heavy drinking is dangerous, but the research suggests otherwise. Drinking as little as two alcoholic beverages per day—often considered moderate—can increase the lifetime risk of colorectal cancer by at least 25%. This highlights an important shift in how we think about alcohol. It is not just excessive use that matters; consistent, moderate intake over time can also contribute to long-term health risks.

3. The Risk Builds Over Time.

Colorectal cancer risk from alcohol is dose- and time-dependent. In simple terms, the more frequently and longer a person drinks, the higher the risk becomes. Experts note that individuals who drink regularly for 10 years or more face a significantly increased likelihood of developing colorectal cancer. Even stopping alcohol use does not immediately erase the risk—it may take years for the body to recover.

4. Alcohol Disrupts Gut Health.

Another major takeaway is the effect alcohol has on the gut microbiome, which plays a critical role in overall health. Alcohol can alter the balance of bacteria in the digestive system, weakening the body’s natural defenses.

This disruption can lead to inflammation, oxidative stress, and further DNA damage—all of which are closely linked to cancer development. A healthy gut environment is essential, and alcohol can significantly interfere with it.

5. Lifestyle Choices Can Help Reduce Risk.

The good news is that colorectal cancer risk is not entirely out of your control. Experts emphasize that healthy lifestyle habits can make a real difference. Reducing or eliminating alcohol intake is one of the most impactful steps. In addition, regular exercise, maintaining a healthy weight, avoiding smoking, and eating a fiber-rich diet all play important roles in lowering risk. Even small changes—such as moving more throughout the day or improving dietary choices—can contribute to better long-term health outcomes.

Take Charge of Your Health with Preventive Screening!

Colorectal cancer often develops silently, with few or no symptoms in its early stages. That is why screening is so important. Early detection can significantly improve outcomes and even prevent cancer by identifying precancerous changes.
