What Screenings Are Recommended for Preventing Stomach Cancer?

To effectively prevent stomach cancer, it's crucial to undergo regular screenings and check-ups. Stomach cancer, when detected early, has a significantly higher chance of successful treatment. Here are the most recommended screenings that can help in early detection and prevention:

1. Helicobacter pylori Testing

Helicobacter pylori (H. pylori) infection is one of the most significant risk factors linked to stomach cancer. This bacterial infection can cause chronic inflammation and ulcers in the stomach lining. Getting tested for H. pylori, especially if you have a family history of stomach cancer or live in a high-risk region, is an important preventive step.

2. Gastroscopy – The Most Effective Screening Method

Gastroscopy, or upper endoscopy, is currently the most valuable diagnostic tool for detecting early-stage stomach cancer. During this procedure, a flexible tube with a camera is inserted through the mouth to examine the stomach lining. It allows doctors to identify abnormal tissue and take biopsies if necessary. This method is highly effective in catching tumors before symptoms appear.

3. Barium Meal Examination (Less Common Today)

In the past, a barium meal X-ray was widely used to detect abnormalities in the stomach. While it's less common now due to advancements in endoscopic technology, it may still be used in certain cases where endoscopy is not available or suitable.

4. Blood Tests and Tumor Marker Screening

For individuals at higher risk, blood tests such as serum gastrin levels and tumor marker tests (like CEA and CA 19-9) can offer additional insights. Although these tests are not definitive on their own, they can help monitor changes and guide further investigations.

From a medical standpoint, men over the age of 40 should consider undergoing these screenings every 1 to 3 years, especially if they have risk factors such as a family history of stomach cancer, dietary habits involving high intake of salted or preserved foods, or origins from regions with high stomach cancer incidence.

Early detection plays a vital role in improving treatment outcomes. When stomach cancer is diagnosed at an early stage, the 5-year survival rate is dramatically higher compared to late-stage diagnosis. Therefore, proactive screening and timely intervention are key to managing and preventing the progression of this disease.

If you fall into a high-risk group, it's highly recommended to consult with your healthcare provider about starting screening at an earlier age. Preventive measures, combined with regular medical evaluations, can significantly reduce your risk and improve long-term health outcomes.
