How much is the probability of gastroscopy biopsy cancer?

Gastroscopic

biopsy is a method of detecting abnormal local lesions during gastroscopy, and then using tools to pick up some of the diseased tissues and perform pathological examination. For normal people, the cancer rate of gastroscopic biopsy may only be 1%-4%. However, if there are some risk factors for gastric cancer, such as long-term drinking, gastric ulcers, gastric polyps, or family history of gastric cancer, the cancer detection rate will increase relatively, but the specific value is still uncertain.
