Stomach cancer arises as a malignant ulcer in the lining of the stomach. This is also called gastric cancer. Stomach cancer is the second most common cause of cancerous deaths and the fourth most commonly diagnosed cancer in the world.
Adenocarcinoma is the most common type of gastric cancer and it can be classified into intestinal and diffuse types. In intestinal adenocarcinoma the cells are arranged in tubular or glandular pattern. Intestinal adenocarcinomas are further classified as tubular, papillary and mucinous. Diffuse adenocarcinomata lack any kind of structural formations. They infiltrate the gastric walls and this condition is called Linitis Plastica.
Gastric cancer is a multifactorial disease and the exact cause remains unknown. The various risk factors are:
A gastroscope is a fibre optic camera fitted tube which is inserted into the stomach to visualize and examine it. Any abnormal tissue found is removed and examined under the microscope. A biopsy is the best method to detect cancer.
This is also called a barium x-ray. Once the barium solution is ingested, x-rays of the stomach, esophagus and intestine are taken to look for abnormalities.
A computed tomography helps in examining the stomach and its adjacent tissues.
