Early Screening Indicators for Stomach Cancer

Stomach cancer can be difficult to detect in its early stages, but several screening methods are commonly used to identify potential signs of the disease. One of the most effective tools is gastroscopy, which allows doctors to directly examine the inside of the stomach and detect abnormalities such as inflammation, ulcers, or cancerous growths. In addition to gastroscopy, other diagnostic tests may be recommended, including abdominal ultrasound and CT scans to evaluate the surrounding organs and tissues.

Another important aspect of early detection involves blood tests that measure specific biomarkers, such as CEA (carcinoembryonic antigen), CA199, AFP (alpha-fetoprotein), and CA125. While these markers are not exclusive to stomach cancer, elevated levels may suggest the presence of a gastrointestinal disorder, including gastric, pancreatic, or colorectal issues. It's important to note that no single tumor marker is 100% specific to stomach cancer, so these tests are usually used in combination with imaging and endoscopic procedures.

Individuals experiencing persistent digestive symptoms should consider screening. Common warning signs include abdominal discomfort, bloating, belching, acid reflux, and even black stools, which could indicate internal bleeding. When such symptoms occur regularly, gastroscopy becomes a crucial diagnostic tool for determining whether the underlying cause is gastritis, an ulcer, or something more serious like gastric cancer.

In summary, early detection of stomach cancer relies on a combination of clinical symptoms, laboratory tests, and advanced imaging techniques. Regular check-ups and timely gastroscopy can significantly improve diagnosis and treatment outcomes.
