This document summarizes carcinoma of the stomach, including its anatomy, blood supply, classification, risk factors, common sites, spread, and surgical management. It notes that stomach cancer can be classified as intestinal, diffuse, or unclassified based on histological features. Risk factors include conditions like HNPCC or pernicious anemia. Surgical options include partial or total gastrectomy depending on the location and extent of the cancer, often with removal of nearby organs.
