How long does it take for chronic gastritis to develop into gastric cancer

Many patients with chronic gastritis are very worried that chronic gastritis will turn into cancer. According to foreign studies, chronic superficial gastritis is related to the incidence of gastric cancer, but chronic gastritis itself, whether chronic superficial gastritis or chronic atrophic gastritis, will not directly develop into gastric cancer, unless chronic atrophic gastritis develops atypical hyperplasia after many years.

Four benign stomach diseases may develop into stomach cancer

Although not all stomach diseases will eventually develop into stomach cancer, patients with four types of stomach diseases should be particularly careful about cancer.

Atrophic gastritis. The final outcome of most atrophic gastritis is gastric cancer. Some people even believe that atrophic gastritis is the "pre-cancer stage of gastric cancer." It is recommended that patients with atrophic gastritis undergo a gastroscopy every two years to detect gastric cancer earlier.

Large gastric ulcers. A large gastric ulcer is one with a diameter greater than 2 cm. Once a large ulcer is found, it should be treated immediately and for at least 6 weeks. After the ulcer is cured, it should be re-examined regularly, with an interval of 6 months or 1 year.

Polyps. Once gastric polyps are detected, no matter how big or small they are, they should be removed and pathological examination should be performed.

Remnant stomach. Part of the stomach is removed due to a certain disease, which is called a remnant stomach. The remnant stomach is closely related to gastric cancer. Some studies have shown that if the remnant stomach exists for more than 5 years, the risk of gastric cancer increases. Therefore, patients with remnant stomach who have undergone gastric surgery are reminded to undergo a gastroscopy every year.
