summary

Gastric cancer is a kind of gastric cancer, cancer occurs in the greater curvature of the stomach. The stomach is composed of two walls, the front and back walls are connected in a curved shape, and the upper edge is short, which is called small curvature of stomach, and the concave is upward to the right; The lower margin is long, which is called great curvature of stomach, protruding to the left and down. There are three types of carcinoma of the greater curvature of the stomach: protuberant ulcer type, ulcer type and protuberant type. Most of the tumors with a diameter of less than 2cm are small, while those with a diameter of less than 2cm are rare. According to the cell types, the types of adenocarcinoma in the greater curvature of stomach can be divided into six types: poorly differentiated adenocarcinoma, adenocarcinoma, signet ring cell carcinoma, tubular adenocarcinoma and mucinous adenocarcinoma. In general, the incidence of gastric cancer patients with ulcerative protuberance is the highest, most of them are poorly differentiated adenocarcinoma, lesions larger than 2cm in diameter are more common, less HP infection. Cancer symptom of great curvature of stomach? Let's talk about it.

Cancer symptom of great curvature of stomach?

Protuberant type: the lesions mostly occur in the antrum of pylorus, near the cardia and the posterior wall of the upper part of the stomach. 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.

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.

Sunken type: the lesions are mainly located in the anterior area of pylorus, greater curvature and 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.
