Stomach cancer develops when malignant cells begin to grow somewhere in the five layers that form the stomach lining. Most stomach cancers start in the innermost layer, the mucosa, which contains glands that produce stomach acid and enzymes to aid digestion. Called adenocarcinomas, these account for up to to 95 percent of all stomach cancers. 

If you or a loved one have stomach cancer and come to Yale Medicine, you will be seen by a team of cancer specialists who work collaboratively to plan treatment. Our team includes radiation oncologists who can administer external beam radiation therapy, a method in which a machine aims high-energy X-ray beams at the tumor area.
