One of the most lethal public health problems globally, especially among high-risk nations, is gastric cancer. Screening would bring improved results through the identification of precancerous lesions and early gastric cancers at the optimal time for treatment. Among all the many screening tests, upper GI endoscopy is the gold standard for the diagnosis of oesophageal, stomach, and small intestine disease.
