Stomach cancers grow slowly over the years, before they can be detected
Some changes occur in the lining of the stomach during the pre-cancer stage but the symptoms are so small that they are often neglected and therefore go undetected. Types of Stomach Cancer There are different types of stomach cancers like: Adenocarcinomas This is the most common type of stomach cancer and it develops from the gland cells in the innermost lining of the stomach, known as the mucosa. If you have been diagnosed with stomach/gastric cancer, chances are it is adenocarcinomas. Gastrointestinal stromal tumors (GISTs) This type of cancer starts from the walls of the stomach and then continues to spread and grow tumors in other parts of the body. GIST can start anywhere in the body’s digestive track, however, in most cases it starts in the stomach. Lymphomas: Lymphomas starts in the lymphocytes, cells that constitute the immune system. Lymphomas starts usually in other parts of the body, but in some cases it is known to begin in the stomach.
