In early stage of gastric cancer, the gastroscopic manifestations are as follows: 1. the mucosal edge of the stomach is rough and not smooth enough; 2. bleeding or erosion appears in the stomach; 3. the diameter of the tumor is small at this time, which is difficult to detect without careful observation. In addition, early gastric cancer is clinically divided into three types, namely, augmented, superficial and indurated, and their gastroscopy shows different symptoms, such as augmented gastric cancer fluid, which mainly exists on the gastric mucosa and will be accompanied by symptoms such as congestion, redness, swelling and ulceration. Superficial gastric cancer will show mucosal erosion and granularity, and the body usually does not show any uncomfortable reaction. In depressed gastric cancer, the mucous membrane is nodular or granular, usually accompanied by congestion and erosion, etc. At this time, the cancer cells in the stomach have not yet spread, so the treatment rate is still relatively high, so as not to delay the disease and cause aggravation. During this period, patients should pay more attention to rest and avoid staying up late, and eat a light diet with easy to digest food and avoid spicy and stimulating food.
