What are the four items for gastric cancer screening

The four items of gastric cancer screening include pepsinogen, gastrin, Helicobacter pylori detection and age and gender factors. Now it is usually combined with five items for a more comprehensive assessment.

1. Pepsinogen detection

Pepsinogen is an important indicator of gastric mucosal health. By testing the levels of pepsinogen I and II, we can preliminarily determine the degree of gastric mucosal atrophy. Low levels of pepsinogen may indicate the risk of gastric mucosal atrophy or even cancer. This test is like a health check for the stomach to see if there are any potential hidden dangers.

2. Gastrin test

Gastrin is a hormone that promotes gastric acid secretion. Abnormal gastrin levels may be associated with the development of gastric cancer. By testing gastrin, it can help assess the functional status of the stomach. Imagine that it is like checking the "vitality index" of the stomach to see if it is working properly.

3. Helicobacter pylori (HP) detection

Helicobacter pylori infection is one of the important risk factors for gastric cancer. Through breath tests, serological tests or gastroscopy biopsy, it is possible to determine whether or not a person is infected with Helicobacter pylori. Timely detection and treatment of Helicobacter pylori infection can effectively reduce the risk of gastric cancer. It is like discovering and eliminating "potential enemies" in advance to protect the health of the stomach.

4. Age and gender factors

Age and gender are also important considerations for gastric cancer screening. Generally speaking, the older you are, the higher your risk of gastric cancer, and the incidence rate in men is higher than in women. Understanding these factors can help doctors develop more personalized screening plans. It's like customizing a health plan based on a person's "background information."

5. Comprehensive scoring and evaluation

Combining the above four indicators, doctors usually calculate a comprehensive score. This score helps doctors assess the risk of gastric cancer more comprehensively and decide whether further examinations or interventions are needed. This score is like a "risk radar" that helps us detect possible health problems more accurately.

In order to better protect the health of the stomach, it is recommended to conduct regular gastric cancer screening, especially for people with a family history or high-risk factors. Maintaining a healthy lifestyle and avoiding excessive drinking, smoking and unhealthy eating are also important measures to prevent gastric cancer. Through these methods, we can better prevent and detect gastric cancer early and protect our health.
