Can Chronic Gastritis with Erosion Lead to Cancer?

Chronic gastritis with erosion is typically a benign condition and does not usually lead to cancer. In most cases, patients can manage the condition effectively with prescribed medication and proper treatment plans. However, if chronic gastritis—especially superficial gastritis—progresses to atrophic gastritis and remains untreated over a long period, there is a small risk (less than 1%) of developing gastric cancer.

One of the most effective ways to reduce this risk is early eradication of Helicobacter pylori, a bacterium commonly linked to stomach inflammation and ulcers. Treating the underlying infection and managing gastritis can significantly lower the chances of progression to more severe conditions.

It's also crucial for patients to undergo a gastroscopy to assess the extent of inflammation, atrophy, and any potential mucosal changes in the stomach lining. Gastroscopy allows doctors to detect early signs of intestinal metaplasia or dysplasia, which are considered precancerous changes.

Depending on the severity of the condition, some patients may need regular follow-up endoscopies every 3 to 6 months, while others may require monitoring every 2 to 3 years. The frequency of these exams should be determined by a medical professional based on individual risk factors and findings from previous tests.

While the vast majority of chronic gastritis cases are non-cancerous, less than 1% of patients may experience malignant transformation, especially when atrophy, intestinal metaplasia, or dysplasia is present. These individuals must adhere strictly to their doctor's recommendations for ongoing endoscopic surveillance and biopsy evaluations.

In summary, chronic gastritis with erosion is generally manageable and poses a very low risk of cancer when properly diagnosed and treated. Regular check-ups and timely intervention are key to preventing complications.
