Gastrointestinal Cancer

What are the symptoms of gastrointestinal (GI) or stomach cancer?

A Answers (7)

  • The majority of stomach cancer patients have non-specific complaints, such as:

    • Indigestion or heartburn
    • Abdominal discomfort (bloating, belching, gas pains, etc.)
    • Loss of appetite
    • Occasional vomiting
    • Diarrhea or constipation
    • Unexplained weight loss
    • Decreased ability to eat a large meal

    These symptoms could be associated with less serious diagnoses like gastritis or peptic ulcer disease, so don’t assume you have stomach cancer should you experience some of them. However, if symptoms persist - especially after treatment - further investigation should be made.

    Other less common, yet serious, symptoms are:

    • Difficulty swallowing
    • Vomiting blood or blood in the stool

    Should you experience these symptoms, don’t delay medical attention.

    Many times, gastrointestinal (GI) or stomach cancer does not cause symptoms until it is fairly advanced. You may notice pain with eating or significant reflux pain. Some people experience a vague discomfort in the middle part of the abdomen just underneath the breastbone. Stomach cancer may also be noticed because of anemia or low hemoglobin levels. Significant weight loss and vomiting are often a sign of advanced cancer.

    Malignancies of the stomach generally occur later in life, after age 50. Tumors that burrow into the stomach wall often produce symptoms that resemble those associated with ulcers. Eating a full meal can become impossible if growths extrude into the hollow of the organ or spread through the stomach wall, making it too stiff to expand. Warning signs include bleeding, persistent vomiting, a constant sense of nausea or fullness that interferes with normal eating, and weight loss. Stomach cancer usually requires the surgical removal of all or part of the stomach.

    Dr. Robynne Chutkan - What are the symptoms of stomach cancer?

    Gastroenterologist Dr. Robynne Chutkan discusses the symptoms of stomach cancer. Watch Dr. Chutkan's video for information on digestive disorders and gastrointestinal issues.

  • Early symptoms of gastric cancer include indigestion and stomach pain or discomfort; a sense of fullness in the upper abdomen especially after eating, loss of appetite, and mild nausea. More advanced stomach cancer may produce unexplained weight loss, stomach pain, vomiting, tarry (black) stool, trouble swallowing, jaundice (yellowing of the skin and eyes), and swelling of the abdomen.

    The symptoms of stomach cancer are vague and often mimic those of much more common and benign disorders such as ulcers or inflammation of the stomach. Symptoms include upper abdominal pain, but there may be no symptoms at all. Some patients' only sign of stomach cancer is anemia found on routine blood work. The diagnosis is made typically by upper endoscopy with biopsy.
