Gastric Cancer Surgery

Gastric cancer is a growth of abnormal cells in the stomach to invade and destroy other organs such as the esophagus and small intestine. It is a malignant tumor whose origin can be genetic, by infection with the bacterium Helicobacter pylori, for different components in the diet or environmental factors. Gastric cancer is difficult to detect in its early and sometimes no symptoms. In general, when the symptoms occur, the tumor is usually well advanced. The most common manifestations are heaviness after meals, heartburn, abdominal pain, nausea, vomiting, loss of appetite and weight, difficulty swallowing or bleeding, among others. The most common treatment is the removal of part or all of a sick stomach, besides extraction sometimes other organs or lymph nodes draining the stomach. Other treatment options include radiation and chemotherapy.
