Stomach (Gastric) Cancer Diagnosis

Advanced Technology and Expertise

To detect and diagnose stomach cancer, our doctors perform thorough exams. They ask questions about your past health and symptoms. They will evaluate you using the latest technology, including:


  • A biopsy also may be indicated. If so, the doctor will remove a sample of stomach tissue during an endoscopy. The tissue sample goes to the lab. It’s looked at under a microscope to help diagnose your condition.

CT Scan

  • A CT or CAT Scan uses X-rays to make a detailed picture of the structures inside your body. You lie on a table while the scanner sends a series of X-ray pulses through your body. An iodine dye (contrast material) is often injected to make structures and organs easier to see on the CT pictures.

Endoscopic Ultrasound (EUS)

  • We are one of the few providers in the region offering endoscopic ultrasound (EUS). By combining the technologies of endoscopy and ultrasound, EUS greatly improves the ability to diagnose stomach cancer.

Positron Emission Tomography (PET) Scan

  • The PET scan uses a special camera to see organs in the body. The camera records a tracer (radioactive sugar) that is put into a vein. Cancer cells use more sugar than normal cells, so the tracer shows up in the cancer cells.

Upper Gastrointestinal Endoscopy

  • An upper gastrointestinal endoscopy allows your doctor to look at your esophagus, stomach and part of your small intestine. While you are sedated, a tube is inserted into the mouth. On the tube is a tiny camera that lets the doctor see inside the stomach.

These tests help your health care team:

  • Detect stomach cancer
  • Pinpoint its location
  • Decide what kind of stomach cancer it is
  • Learn how far it has spread (also called staging)
  • Develop a stomach cancer treatment plan

This information helps the team decide on the best way to treat you.

Clinical Trials

Medical research finds ways to help people live longer, improve their quality of life and manage or cure disease. This is possible because of the people who volunteer to participate in clinical trials.
