Stomach cancer screening with upper endoscopy in Los Angeles

Stomach Cancer Screening in Los Angeles, CA

Stomach (gastric) cancer is often silent in its early stages, which makes screening important for people at increased risk. At LA Integrative Gastroenterology & Nutrition, our physicians use upper endoscopy and a risk-based approach to screen for gastric cancer and monitor precancerous changes in patients with a family history, chronic gastritis, H. pylori infection, or other risk factors.

When Is Endoscopic Stomach Cancer Screening Recommended?

Upper endoscopy is the primary tool for gastric cancer screening. It allows direct visualization of the stomach lining and biopsy of any suspicious areas. In the United States and other low- and intermediate-incidence countries, routine population-wide screening is not generally recommended. Instead, a risk-based approach focuses on people with specific risk factors or precancerous findings.

Key Indications for Endoscopic Screening

  • Origin from high-incidence regions: people from or with ancestry in areas such as Japan, South Korea, and parts of China, where population-based endoscopic screening programs have shown reduced mortality
  • Family history: especially a first-degree relative with gastric cancer
  • Precancerous gastric lesions: gastric intestinal metaplasia or chronic atrophic gastritis, which may require surveillance endoscopy
  • Pernicious anemia: associated with increased gastric cancer risk
  • Prior partial gastrectomy: for benign disease, due to increased cancer risk in the remaining stomach
  • Hereditary cancer syndromes: such as hereditary diffuse gastric cancer (CDH1 mutation) and Lynch syndrome, per guideline recommendations
  • H. pylori infection: chronic infection is a major risk factor and should be tested for and treated
  • Personal history: of gastric or other digestive cancers

Why Early Detection Matters

Stomach cancer often causes no symptoms in its early stages, and by the time symptoms such as weight loss, early fullness, persistent indigestion, anemia, or black stools appear, the disease may be advanced. Identifying and monitoring precancerous changes in high-risk individuals allows earlier intervention and better outcomes.

Reducing Your Risk

Testing for and eradicating H. pylori, limiting heavily salted, smoked, and processed foods, not smoking, eating plenty of fruits and vegetables, and treating chronic gastritis can help reduce risk. Your physician can incorporate these strategies into a customized nutrition plan and inflammation control program.

Stomach Cancer Screening FAQs

Who should be screened for stomach cancer?

Screening is generally recommended for people at higher risk, such as those with a family history, precancerous stomach changes, pernicious anemia, certain hereditary syndromes, prior partial gastrectomy, or ancestry from high-incidence regions.

How is stomach cancer screened?

Upper endoscopy is the main screening tool. It allows the doctor to examine the stomach lining and take biopsies of any suspicious areas.

Does H. pylori increase stomach cancer risk?

Yes. Chronic H. pylori infection is a major risk factor. Testing and treating the infection can reduce risk.

What is gastric intestinal metaplasia?

It is a change in the stomach lining that can be a precursor to cancer. Patients with this finding may need periodic surveillance endoscopy.

What are early symptoms of stomach cancer?

Early stomach cancer often has no symptoms. Later symptoms may include indigestion, early fullness, weight loss, anemia, nausea, or black stools.

Is routine screening recommended for everyone in the U.S.?

No. In the U.S., a risk-based approach is used rather than population-wide screening.
