Abstract
Stomach cancer, also called as gastric cancer, is a malignant tumor arising from the lining of the stomach. Somehow, there has been a significant decrease in the number of people diagnosed with gastric cancer for the past 60 years. According to the American Cancer Society, the estimated numbers of new cases are 21,320 and deaths from gastric cancer are 15,070 in the USA. The exact reason why a cell becomes cancerous is unclear, but when something damages or alters certain genes in the cell, it may get cancerous. This makes the cell abnormal and multiplies out of control. A cancerous tumor starts from one abnormal cell. Stomach cancers are classified according to the type of tissue where they originate. The most common type of stomach cancer is adenocarcinoma. Gastric cancer cells can spread by breaking away from the original tumor. They enter the blood vessels or lymph vessels, through which they can travel to all the tissues of the body. This process is called metastasis. This article discusses about cancer and how stomach cancer spreads, stages, causes, symptoms, diagnosis, and treatment of gastric cancer.
