Causes Of Gastric Cancer
Cancer is a lethal disease, which occurs when some kind of mutation takes place in a cells DNA
. This mutation causes the cells to develop and segregate at a fast pace and to go on living even when the normal cells would expire. These accumulating cells are cancerous and they form a tumor which can even invade the surrounding areas. These cancer cells can even split from the tumor and spread all through the body. Gastric cancer is a type of cancer in which the malignant tumor arises from the lining of the walls of the stomach.
The exact causes of gastric cancer or stomach cancer are still not known. However, the following factors are known to increase the chances of the occurrence of gastric cancer :-
