Stomach cancer can be diagnosed by gastroscopy.

Gastric cancer can be diagnosed by gastroscopy. Gastroscopy can directly observe the mucosa in gastric tissue. If abnormal space-occupying lesions are found in the stomach during the examination, the doctor will also remove some tissues under gastroscopy for pathological biopsy to clarify the nature of the mass so as to facilitate the formulation of the next treatment plan. If the pathological examination results are malignant after gastroscopy, the patient needs to immediately remove the tumor. For patients who cannot undergo surgery, drug chemotherapy and radiation therapy can also be selected to control tumor growth.
