Early stomach cancer often does not cause symptoms. As the cancer grows, the most common symptoms are:

• Discomfort or pain in the stomach area



• Difficulty swallowing



• Nausea and vomiting



• Weight loss



• Feeling full or bloated after a small meal



• Vomiting blood or having blood in the stool

Most often, these symptoms are not due to cancer. Other health problems, such as an ulcer or infection, can cause the same symptoms. Anyone who has these symptoms should tell their doctor so that problems can be diagnosed and treated as early as possible.

If you have symptoms that suggest stomach cancer, your doctor will check to see whether they are due to cancer or to some other cause. Your doctor may refer you to a gastroenterologist, a doctor whose specialty is diagnosing and treating digestive problems.

Your doctor will ask about your personal and family health history. You may have blood or other lab tests. You also may have:

• Physical exam: Your doctor feels your abdomen for fluid, swelling, or other changes. Your doctor also will check for swollen lymph nodes.



• Endoscopy: Your doctor uses a thin, lighted tube (endoscope) to look into your stomach. Your doctor first numbs your throat with an anesthetic spray. You also may receive medicine to help you relax. The tube is passed through your mouth and esophagus to the stomach.



• Biopsy: An endoscope has a tool for removing tissue. Your doctor uses the endoscope to remove tissue from the stomach. A pathologist checks the tissue under a microscope for cancer cells. A biopsy is the only sure way to know if cancer cells are present.
