Biopsy
The biopsy is a procedure in which tissues or cells are removed from the body for further analysis under the microscope. This test is often done right after the endoscopy to confirm the presence of stomach cancer. In most cases, your doctor will check the number of HER2 genes in a sample and the number that is being made. If the level is higher than usual, it is likely that you are suffering from stomach cancer. [6]
