Discovering the Truth: Unexpected Links between Alcohol and Cancer
Since time immemorial, certain types of cancer have been known to have a direct connection with alcohol consumption. However, the picture expands beyond what was initially believed.
Pilar López Criado, leader in the Lung, Head and Neck Tumors, and Melanoma Section at the MD Anderson Cancer Center Hospital in Madrid, highlights in an interview that breast cancer and other types of hormone-dependent tumors may experience an increased risk 10% or more in women who consume high amounts of alcohol.
A Range of Risks
The danger is not limited to a few types of cancer. It spreads to various areas of the body, including the liver, esophagus, pancreas, mouth, throat, larynx, colon, and rectum. Both men and women are at risk, with studies suggesting an increased incidence of several types of cancer with alcohol consumption.
Alcoholic beverages, from wine to beer, are all potential culprits. According to the United States Centers for Disease Control and Prevention (CDC), the risk of cancer increases with each drink.
The Process Behind the Danger
When we drink alcohol, our body transforms it into a substance called ‘acetaldehyde’. This substance damages DNA, the instruction manual of our cells, and hinders their ability to repair. The result can be uncontrolled growth of cancer cells.
Dr. López warns that the impact of alcohol extends beyond the development of cancer, also affecting its treatment due to the alterations it produces in vital organs such as the liver, brain and mucous membranes.
Beyond Alcohol: Other Factors at Play
Alcohol is not alone in this deadly dance. It is associated with a number of behaviors and substance exposures that increase the risk of cancer. In addition to directly damaging DNA, acetaldehyde impairs the body’s ability to absorb essential nutrients, such as vitamins A, B, C, D, and E, as well as carotenoids, all linked to cancer prevention.
Hormonal consequences
Alcohol can also influence the body’s levels of estrogen, a hormone linked to breast cancer. Additionally, alcohol products may contain contaminants such as nitrosamines and asbestos, which further exacerbate the risk of cancer.
The Dilemma of Quantities
When it comes to how much is too much, the answer is not simple. Dr. López warns that any amount of alcohol carries risks. Although some guidelines suggest moderation, the safest recommendation is to avoid it altogether.
In a world where alcohol is ubiquitous, especially in Spain with its rich wine culture, the idea of abstaining can seem challenging. However, health must take precedence over the social and economic comforts associated with alcohol consumption.
Youth at Risk
Young people are particularly vulnerable, as excessive alcohol consumption is commonly associated with social and festive activities. This habit, combined with other toxins such as tobacco, creates a dangerous cocktail that can have devastating long-term consequences.
In conclusion, cancer prevention begins with individual decisions. Avoiding alcohol, especially in youth, may be one of the most effective measures to reduce the risk of this deadly disease.
