Stomach (Gastric) Cancer Prevention

You May Be Able to Reduce Your Risk

We don’t know the exact cause of stomach cancer. But we do know that certain things increase your risk of getting it. You may be able to change your behavior and reduce your risk. 

Stomach Cancer Risk Factors

You are more likely to get stomach cancer if you:

  • Are obese
  • Drink alcohol
  • Eat a diet rich in smoked foods, salted fish or seafood caught in the ocean, salted meat and pickled vegetables
  • Have a history of H. pylori or other bacterial infections of the stomach
  • Have had previous stomach surgery
  • Smoke 

A diet rich in whole grains, fresh fruits and vegetables may lower your risk of stomach cancer.

Stomach Cancer Symptoms

The symptoms of stomach cancer include:

  • A sense of fullness in the upper abdomen, just below the chest bone after eating a small amount of food
  • Abdominal pain or vague discomfort
  • Heartburn or indigestion 
  • Nausea or vomiting, especially if blood is present
  • Swelling of the abdomen 
  • Unintended weight loss and lack of appetite

If you have any of these symptoms, call your doctor or make an appointment with The University of Kansas Cancer Center.
