All gastric mesenchymal tumors grow all the time. Gastric mesenchymal tumors are generally referred to as gastrointestinal mesenchymal tumors and are classified as benign lesions, potentially malignant lesions, and malignant lesions based on the malignancy of the tumor. Gastric mesenchymal tumors grow faster or slower depending on the type of pathology. If it is a benign lesion or potentially malignant lesion, the tumor grows slowly or even remains unchanged for a long time. But if it is malignant, the growth rate of gastric mesenchymal tumors increases very rapidly. Before formal treatment such as surgical resection, gastric mesenchymal tumors will basically keep growing, and can gradually increase in size to the surrounding tissues, such as compression and other manifestations. When the patient stomach after the occurrence of mesothelioma, should go to the hospital in time for examination, under the guidance of the doctor to choose the appropriate way for formal treatment. Early control of the condition. For fast-growing gastric mesenchymal tumors must be timely surgical resection, and after surgery, appropriate radiotherapy or targeted therapy (such as imatinib, sunitinib, regorafenib, etc.) should be carried out according to the pathological situation.
