A little bit of alcohol was once thought to be good for you. However, as scientific research advances, we’re gaining a clearer picture of alcohol’s effects on health—especially regarding cancer.
The complex relationship between alcohol and cancer was recently highlighted in a new report from the American Association for Cancer Research. The report’s findings are eye-opening.

The report estimates that 40% of all cancer cases are linked to “modifiable risk factors,” meaning things we can change ourselves. Alcohol consumption is a significant factor among them.
Alcohol consumption is associated with six types of cancer, namely head and neck cancers, esophageal cancer, liver cancer, breast cancer, colorectal cancer, and stomach cancer.
The statistics are alarming. In 2019, more than 5% of cancer diagnoses in the West were directly linked to alcohol consumption, and this figure is steadily increasing.
This figure challenges the common belief that alcohol is a harmless social lubricant and is based on several well-conducted studies linking alcohol consumption to cancer risk.

The report highlights a concerning trend: increasing rates of certain cancers among younger adults. Researchers are still trying to understand this unexpected development, but alcohol consumption is emerging as a potential leading cause.
Of particular concern is the rising incidence of early-onset colorectal cancer among adults under 50. The report notes a 1.9 percent annual increase between 2011 and 2019.
While the exact causes of this trend are still being investigated, research consistently shows a link between frequent and regular drinking in early and mid-adulthood and a higher risk of colon and rectal cancers later in life.

Unlike many risk factors for cancer, alcohol consumption is one we can control. Reducing or eliminating alcohol intake can lower the risk, offering a form of empowerment in the face of an often unpredictable disease.
The relationship between alcohol and cancer risk generally follows a dose-response pattern, meaning simply that higher levels of consumption are associated with greater risk.
Even light to moderate drinking has been linked to increased risk for some cancers, particularly breast cancer.
Yet it’s crucial to remember that while alcohol increases cancer risk, it doesn’t mean everyone who drinks will develop cancer. Many factors contribute to cancer development.

Damages DNA
The story doesn’t end with these numbers. It extends to the very cells of our bodies, where alcohol’s journey begins.
When we drink, our bodies break down alcohol into acetaldehyde, a substance that can damage our DNA, the blueprint of our cells.
Alcohol can potentially rewrite our DNA and create changes called mutations, which in turn can cause cancer.
The tale grows more complex when we consider the various ways alcohol interacts with our bodies.
It can hinder the absorption of nutrients and vitamins, disrupt hormone levels, and facilitate the infiltration of harmful chemicals into cells in the mouth and throat.
It can affect the bacteria in our guts, the so-called microbiome, which is not just a part of us, but a crucial player in our health and well-being.
Alcohol consumption is linked to other aspects of our health and lifestyle, so it’s crucial to consider this alongside other factors.
Tobacco use and smoking can significantly amplify the cancer risks associated with alcohol.
Our genetic makeup also contributes, as specific variations can influence how our bodies process alcohol.

Physical inactivity and obesity, often associated with heavy drinking, separately increase cancer risks. Alcohol exacerbates these risks.
Despite prevalent misconceptions, it is important to note that the type of alcoholic beverage consumed, whether it is beer, wine, or spirits, does not significantly impact the risk of developing cancer.
The primary carcinogenic factor lies in ethanol, which is the chemical compound responsible for the intoxicating effects of alcohol.
While some studies have suggested that red wine may have protective effects against certain diseases, there is no clear evidence that it helps prevent cancer. The potential risks of alcohol consumption outweigh any potential benefits.
The takeaway is not that we should never enjoy a glass of wine or a beer with friends, rather, it’s about being aware of the potential risks and making choices that align with our health goals.
It’s about moderation, mindfulness, and informed decision-making.
