summary

An uncle suffered from chronic gastritis before. Recently, he felt very uncomfortable. When he went to the hospital, he was diagnosed with gastric cancer. The doctor said that it was evolved from chronic gastritis. Next, let me introduce to you how precancerous lesions of gastric cancer are.

What is precancerous lesion of gastric cancer

First: suffering from chronic atrophic gastritis. Patients with chronic atrophic gastritis, generally through the gastroscope naked eye observation, the judgment is not accurate, must be sent through biopsy pathology for histological examination, under the microscope to observe the gastric mucosa with chronic inflammation and glandular atrophy can be diagnosed, and it is still a benign lesion. As chronic atrophic gastritis is often accompanied by intestinal metaplasia and atypical hyperplasia of gastric mucosa, it is indeed at risk of gastric cancer.

Second: stomach with atypical hyperplasia is dysplastic gastritis. Abnormal hyperplasia of epithelial cells and glandular cells and loss of original function are the main characteristics of patients with this kind of gastritis, which can be divided into light, medium and heavy grades. Intestinal metaplasia comes from proliferating cells in the neck of gland. Complete intestinal metaplasia is an inflammatory reaction, and incomplete colonic metaplasia is closely related to the occurrence of intestinal gastric cancer.

Third: therefore, when the pathological report of gastric mucosa with atypical hyperplasia (mild) or gastric mucosa with complete intestinal metaplasia, it does not belong to gastric precancerous lesions, the possibility of canceration is very small. For example, precancerous gastritis is also called chronic atrophic gastritis. Chronic gastric ulcer. Gastric polyps. Remnant stomach. Menetrier disease and deep cystic gastritis. However, chronic superficial gastritis and duodenal ulcer are not precancerous diseases and will not turn into cancer.

matters needing attention

Many patients with gastric cancer are often found to have advanced gastric cancer when they are examined, which seems to have no signs. In fact, many gastric diseases may lead to gastric cancer, and precancerous lesions are common. Therefore, we must be cautious.
