Like most types of cancer, stomach cancer does not pose symptoms in early stages. As the cancer grows, however, some people may experience some of the following:
- Pain throughout abdomen or focused over the upper abdomen
- Abdominal pain that worsens after eating
- Poor appetite
- Weight loss (without trying)
- Feeling full after eating only a small meal
- Heartburn, reflux or indigestion
- Nausea
- Vomiting bright red blood, or digested blood (resembles coffee grounds)
- Blood in the stool, bright red or black tarry stool
- Feeling tired or weak, as a result of having too few red blood cells (anemia)
- Swelling or fluid build-up in the abdomen
- A palpable abdominal mass
People with known gastroesophageal reflux disease (GERD), peptic ulcer disease, or hiatal hernia may already experience some of the symptoms listed above. If your symptoms change, worsen, or new symptoms develop, please contact your medical provider. Blood in vomit or bowel movements is not normal and should be reported to your medical provider right away.
Other problems, such as an ulcer or infection may cause these symptoms, too. Be sure to alert your physician to the above issues for a prompt and accurate diagnosis.
