Stomach cancer involves a diagnostic procedure performed to evaluate the medical history. Also, a detailed physical exam is performed. Due to the size of the stomach, the symptoms that arise at an early stage are non-specific. As a matter of fact, the physical findings do not exhibit a substantial sign until the disease reaches its advanced stage. Symptoms including, indigestion, bloating, nausea, sudden loss of appetite, heartburn, discomfort etc. are quite common in people with early-stage stomach cancer.

It helps in examining the inside of the esophagus, duodenum and stomach to determine the abnormal areas.
