Symptoms of Stomach Cancer

The earliest stages of stomach cancer have no symptoms. Many of these symptoms can be caused by other, less serious conditions. However, it is still important to discuss them with your doctor. Early detection and treatment improve outcomes for both cancer and other health conditions.

Symptoms of stomach cancer are vague and are common with many noncancerous conditions, such as indigestion or a gastric ulcer . Over time, symptoms may become more frequent or persistent. The most common symptoms of stomach cancer are:

  • Persistent heartburn or indigestion
  • Feeling full after eating a small amount of food
  • Bloating, especially after eating
  • Nausea
  • Abdominal discomfort and/or pain
  • Fatigue or weakness
  • Decreased appetite
  • Unintended weight loss
  • Worsening pain during or difficulty with swallowing
  • Vomiting, may have blood
  • Blood in the stool
  • Yellowing of the skin and whites of the eyes— jaundice
  • Increase in abdominal girth from fluid build-up— ascites
