Stomach cancer, also called gastric cancer, is a cancer that starts in the stomach. Certain types of H. pylori have greater risks than others. Other common causes include eating pickled vegetables and smoking. Smoking increases the risk of developing gastric cancer significantly, from 40% increased risk for current smokers to 82% increase for heavy smokers. Gastric cancers due to smoking mostly occur in the upper part of the stomach near the esophagus. Some studies show increased risk with alcohol consumption as well.
This is then followed by medical imaging to determine if the disease has spread to other parts of the body. Surgery remains the only curative therapy for stomach cancer. The pathologic examination of the resected specimen shows incomplete resection or deep invasion by tumor, the patient would need a formal stomach resection.
