What are the symptoms of gastric cancer?

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.

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.

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.
