Gastric Adenocarcinoma at 20x Magnification
Scientists have not yet been able to develop a screening test that is specific for stomach cancer. Consequently, a variety of approaches are generally utilized by medical professionals to establish a diagnosis. For instance, fecal occult blood testing is often used to determine if there is any blood present in the stool, while the lining of the stomach may be examined via an endoscope. A biopsy can be performed during endoscopy if any abnormal growths are found. X-rays, computed tomography (CT) scans and magnetic resonance imaging (MRI) are sometimes used to aid diagnosis, but usually play a larger part during the staging of the disease, which entails determining the extent of tumor progression.
