What are the precancerous diseases of gastric cancer?

Precancerous diseases generally refer to precancerous lesions. Precancerous lesions of gastric cancer include atrophic gastritis, gastric ulcer, gastric adenoma polyps, etc. The details are as follows:

1. Atrophic gastritis

Atrophic gastritis is a disease in which the intrinsic glands of the gastric mucosa atrophy, mainly caused by Helicobacter pylori infection, bile reflux and other factors. If patients do not receive clinical treatment in time, as the disease progresses, it will lead to abnormal proliferation of gastric mucosal epithelial cells and intestinal metaplasia, thus evolving into gastric cancer.

2. Gastric ulcer

Gastric ulcer is an ulcer that occurs in the mucosa or deeper layers of the stomach lining. During the repeated damage and repair of local cells, it may become cancerous and lead to gastric cancer.

3. Gastric adenomatous polyps

Gastric adenomatous polyps are a type of gastric polyp, which is a benign lesion in itself. However, studies have shown that it has a risk of developing cancer, and if there is no active intervention, it may become gastric cancer more than ten years later.

In addition to the above common diseases, precancerous lesions of gastric cancer also include residual gastritis, gastric atypical hyperplasia, new diseases, etc. After the patient develops the above diseases, he should seek medical treatment as soon as possible to reduce the incidence of gastric cancer.
