Living with Gastric cancer

Cancer of the stomach, which is hard to find early and mostly affects older adults.

Understanding Gastric cancer

Gastric cancer, also called stomach cancer, is cancer that starts in the stomach.

The stomach mixes food with acid and helps digest protein. About two-thirds of people with stomach cancer are over 65. Risk is higher with a past Helicobacter pylori infection, stomach inflammation, being male, smoking, a family history, or eating lots of salted, smoked, or pickled foods. It is hard to diagnose in its early stages.

Signs & symptoms

Early symptoms can be mild and also come from other problems. GARD lists these:

  • Indigestion
  • Stomach discomfort
  • Blood in the stool
  • Vomiting
  • Unexplained weight loss
  • Trouble swallowing

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Your doctor may refer you to a specialist who knows rare conditions.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
