How is stomach cancer diagnosed?

Usually endoscopy.: Patients with suspicious symptoms are usually referred to a gastroenterologist, who performs an endoscopy. The patient takes sedation medicine, and then the doctor inserts a flexible camera into the stomach and looks for cancer. A piece of the tumor is removed which confirms the cancer diagnosis. Other tests can suggest stomach cancer too.

Upper endoscopy : This is the best test to check your stomach for cancer. Endoscopy with narrow band imaging can help with early lesions under certain circumstances.
