Can gastroscope spot cancer

Gastroscopy is usually unable to diagnose gastric cancer immediately during the examination process. Gastroscopy is to observe whether there are abnormal lesions in the stomach through endoscopy, but it cannot directly see the benign or malignant lesions. If there are suspicious lesions found at the same time, pathological tissues can be taken at the same time of examination, and pathological biopsy or cytological examination can be performed to confirm whether gastric cancer is diagnosed. If gastric cancer is diagnosed, early patients can choose surgery; The patients in advanced stage were mainly treated by surgery, and other comprehensive treatments such as chemotherapy, radiotherapy or biological targeted therapy were given according to the situation after surgery.
