What symptom does gastric cancer have or precursory

summary

Gastric cancer is indeed a serious threat to people's health. The cause of the disease is unknown, which may be related to many factors, such as living habits, diet types, environmental factors, genetic quality, mental factors and so on. Gastroscope is a kind of medical examination method. It extends into the stomach with the help of a thin and soft tube. Doctors can directly observe the lesions of esophagus, stomach and duodenum, especially for small lesions. Under gastroscope, gastric cancer can be shown in three forms. Now let's talk about it.

What symptom does gastric cancer have or precursory

First: protuberant type: lesions occur in the pyloric antrum, near the cardia and gastric body part of the posterior wall. The mucosa showed polypoid protrusion, uneven surface, red color or erosion, and no clear boundary with the surrounding normal mucosa. This situation must be carefully observed.

Second: flat type: the observation of this type shows that the lesion is slightly protruding or lower than the surrounding mucosa. The main characteristics of this type are the change of color on the surface of the mucosa and the sense of rough and irregular particles. The mucosa of the lesion can show localized or extensive redness, discoloration or fading.

Third: depressed type: the lesions are mainly located in the anterior pyloric area, the greater curvature and the cardia. There is a clear boundary between the sunken area and the surrounding normal mucosa. The mucosal folds of the diseased area are irregular and uneven, lose the normal color of the mucosa, and have abnormal red or fading color changes. There are often filthy exudates or bleeding spots. The mucosa gathered to the sunken area may suddenly become thinner or irregular thickening, or even suddenly interrupted. The marginal mucosa often has nodular irregular granules.
