Gastric Cancer


Gastric cancer is often diagnosed at an advanced stage. Among the risk factors include age, gender, genetic factors, smoking, smoke or salt preserved food, diet less of fruits and vegetables, infection with H.Pylori and Epstein Barr Virus. About 90–95% of the tumors are adenocarcinoma.


Surgery is the primary treatment for early stage gastric cancer.
Total or partial gastrectomy is performed together with lymph node dissection. Bypass surgery is done to relieve obstructive symptoms.
