Gastric cancer is the 3rd-most common cause of cancer-related deaths worldwide. The majority of cases are from adenocarcinoma. The modifiable risk factors include Helicobacter pylori infection, smoking, and nitrate-rich diets. Hereditary syndromes, pernicious anemia, and prior partial gastrectomy are among the endogenous risk factors. When symptoms such as epigastric fullness, vomiting, and weight loss occur, it is likely that the cancer is in the advanced stage. Diagnosis is confirmed with esophagogastroduodenoscopy and biopsy. Imaging studies and laparoscopy aid in determining the cancer stage. Consequently, staging dictates the management approach. Management consists of gastrectomy and chemoradiotherapy. Most cases are diagnosed in late stages, indicating a generally poor prognosis.
