Stomach Cancer Screening & Prevention in Los Angeles, CA
Stomach cancer is often silent until it is advanced, which is why understanding your risk matters. At LA Integrative Gastroenterology & Nutrition, our physicians evaluate risk factors such as H. pylori infection, family history, and precancerous stomach changes, and use upper endoscopy to screen and monitor patients who need it most.
Request an AppointmentUnderstanding Stomach Cancer Risk
Stomach (gastric) cancer develops slowly, often over many years, as the stomach lining undergoes precancerous changes. Because early stages rarely cause symptoms, identifying people at higher risk and screening them appropriately is key to early detection.
Major Risk Factors
- H. pylori infection: the most important known risk factor, associated with chronic gastritis and ulcers
- Family history: a first-degree relative with stomach cancer
- Precancerous changes: chronic atrophic gastritis and gastric intestinal metaplasia
- Pernicious anemia
- Prior partial gastrectomy
- Hereditary syndromes: such as hereditary diffuse gastric cancer and Lynch syndrome
- Ancestry: from high-incidence regions such as East Asia, parts of Latin America, and Eastern Europe
- Lifestyle factors: smoking and diets high in salted, smoked, or processed foods
Symptoms to Watch For
See a physician promptly if you experience persistent indigestion, early fullness, unexplained weight loss, nausea or vomiting, upper abdominal pain, iron deficiency anemia, black or tarry stools, or difficulty swallowing.
How Screening Is Performed
Upper endoscopy is the primary screening method. It allows direct examination of the stomach lining and biopsy of any suspicious areas. Screening often begins with testing for and treating H. pylori, which can reduce cancer risk. Patients with precancerous findings may need periodic surveillance endoscopy. For more detail on clinical indications, see our stomach cancer screening indications page.
Prevention Strategies
Alongside screening, our team helps reduce risk through H. pylori eradication, a customized nutrition plan rich in fruits and vegetables, smoking cessation support, and inflammation control. Stomach cancer screening is part of our broader cancer screening program, which includes EsoGuard and the Galleri test.
