Gastric cancer surgery

Gastric cancer is a growth of abnormal cells in the stomach that can spread to other organs such as the oesophagus and small intestine. It is a malignant tumour whose origin can be genetic, by infection with the bacterium helicobacter pylori, from different components in the diet or environmental factors. Gastric cancer is difficult to detect in its early stages and sometimes there are no symptoms. In general, when the symptoms occur, the tumour is usually well advanced. The most common symptoms 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 the stomach, and when necessary, other organs or lymph nodes draining the stomach. Other treatment options include radiation and chemotherapy.
