3. Smoking

Smoking is a major risk factor for stomach cancer, particularly gastric cardia cancer, which occurs where the stomach meets the esophagus.

Research shows that the risk increases with:

  • Longer smoking history
  • Higher cigarette consumption (up to 20 cigarettes per day)

Fortunately, quitting smoking can significantly lower this risk. Studies show that the risk of stomach cancer begins to drop within a few years after quitting and continues to decline over time.
