This model, consisting of two distinctive parts, depicts the adverse effects of cancer on the stomach and its surrounding organs.

• A diseased stomach, esophagus and neighboring anatomical features can be found on the model's top portion, afflicted by various disease states such as gastric ulcer, two common types of gastric tumor and esophageal tumor.

• The bottom portion features a magnified representation of stomach wall histology, including the muscular and mucosal layers, with examples of tumor progression – stages 0 through 3.

• As an educational tool, this piece can be used to show patients the progression of gastric and esophageal cancer by demonstrating how cancer can grow through the gastric wall and spread to other areas via the lymph system.
