How Alcohol Causes Cancer — Insights from the Best Oncologist in Lucknow
In many cultures, including ours, alcohol is synonymous with celebration, socialising, and relaxation — a drink to mark a promotion, a wedding, or just the end of a long week. But what if I told you that with every drink, you are quietly increasing your risk of cancer?
As a cancer specialist in Lucknow, I’ve seen how lifestyle choices can profoundly affect cancer risk — and alcohol is one of the most underestimated causes.
This isn’t about judging personal choices; it’s about sharing a crucial medical fact that often gets drowned out: The World Health Organization (WHO) has classified alcohol as a Group 1 carcinogen. This means it is proven to cause cancer in humans, placing it in the same category as tobacco and asbestos.
How Does Alcohol Cause Cancer?
When our body breaks down alcohol, it converts it into a toxic chemical called acetaldehyde. This chemical can damage our DNA and prevent cells from repairing themselves properly. Over time, these damaged cells may grow uncontrollably — leading to cancer.
Which Cancers Are Linked to Alcohol?
The evidence is strongest for cancers of the:
- Mouth, throat, and voice box
- Liver
- Colon and rectum
- Breast (even low levels of regular drinking can increase the risk)
The Dose Matters — But There’s No “Safe” Limit
A common question I get is, “Doc, how much is okay?”
The hard truth is that any amount of alcohol increases your cancer risk. The more you drink, the higher the danger.
That old saying — “moderate drinking is good for your heart” — has been heavily debated and is outweighed by the cancer risk for most people.
The Indian Context
With changing lifestyles and social habits, alcohol consumption is steadily rising in India — especially in urban areas and among women. This is a concerning trend from a public health standpoint, and one that needs more awareness.
What Can You Do to Protect Yourself?
- The Best Choice: The most effective thing you can do for your cancer risk is not to drink alcohol at all.
- If You Do Choose to Drink: Stick to recommended limits to reduce (but not eliminate) your risk.
- Guidelines: Most health authorities suggest no more than 1 standard drink per day for women and 2 for men.
(One standard drink = 1 small beer (330ml) / 1 glass of wine (100ml) / 1 peg of hard liquor (30ml))
- Guidelines: Most health authorities suggest no more than 1 standard drink per day for women and 2 for men.
- Have More Alcohol-Free Days: Make a conscious effort to have several days each week where you don’t drink at all.
- Avoid Binge Drinking: Consuming a large amount of alcohol in one sitting is particularly harmful.
Your Simple Action Plan
Be mindful. The next time you reach for a drink, pause and think.
Could you celebrate with a fresh juice or mocktail instead? Could you relax with a walk or soothing music?
Small, consistent choices like these can protect your health in the long run.
As the best oncologist in Lucknow – Dr. Harshvardhan Atreya always reminds his patients: Prevention is the first step in fighting cancer. Your health is in your hands — and your body will thank you for every mindful decision you make.
