If there is obvious pain when pressing on the stomach, it is seen in the following cases: First, middle-aged and elderly patients who have recurrent epigastric pain, short term loss of appetite, weight loss, weight loss, or black stool, are considered to have malignant tumor of the stomach. In this case, the tumor will have plasma membrane invasion or involve the adjacent organs, and there will be obvious pressure pain and palpable mass on body examination. The pathological type of malignant tumor that occurs in the stomach is commonly adenocarcinoma, and the cause is related to the malignant transformation of benign ulcers. Secondly, partly due to ulcer disease, it is related to Helicobacter pylori infection, and gastroscopy can make a clear diagnosis, and usually oral medication to protect the gastrointestinal mucosa should be taken.
