The specimen taken by gastroscope is a bit hard, which means that the patient may suffer from gastritis, gastric cancer and other digestive system diseases. 1. Gastritis: chronic gastritis is mostly considered, as gastric acid stimulates the mucosa of stomach wall for a long time, causing the mucosa to be damaged and repaired, and in the long run, the specimen taken by gastroscope will be a bit hard. 2. Gastric cancer: If the patient has gastric cancer, the tumor cells keep proliferating and growing, and the tumor tissues proliferate a lot, the specimen will be a bit hard and brittle, and easy to bleed when touched. However, if the specimen taken by gastroscopy is a bit hard, it can only suspect whether the patient is suffering from gastritis or gastric cancer, and if the diagnosis needs to be confirmed, it needs to be sent for examination and be determined according to the immunohistochemical results of pathological smears, and the diagnosis can’t be confirmed purely on the basis of the specimen being a bit hard.
