In the early stages a patient may experience:
  • Indigestion or stomach discomfort
  • A bloated feeling after eating
  • Mild nausea
  • Loss of appetite
  • Heartburn

In more advanced stages a patient may have:

  • Pain in the stomach
  • Blood in the stool (dark black or red)
  • Vomiting
  • Weight loss
