Gastric Cancer Causes   

Your stomach is a muscular pear-shaped bag organ of the digestive tract. It is located between the esophagus and duodenum, which allows it to receive food chewed in the mouth and swallowed into the esophagus. One of the main functions of the stomach is to provide digestion of foods by its mechanical and chemical functions. It is an important organ that constantly works. However, the stomach can be attacked by many diseases, including cancer.  

The causes of Gastric cancer are not well known. However, cancer occurs, most of times, in precancerous cells or tissue altered by chemical or mechanical injuries. Stomach cancer tends to grow around an existing injury such as atrophic gastritis (chronic inflammation of the stomach mucosa).  

In general, you have Gastric cancer when there are errors in the process of DNA replication of certain cells of your stomach. Genes can be mutated due to a confrontation with a virus, parasite or bacteria. A cell mutation may also be the result of unhealthy lifestyle (pollution exposure, smoking, alcohol and certain unhealthy foods) that lead to genetic changes responsible for abnormal multiplication of cells.  

Although rare, sometimes cell mutations have their origin in their genetic material. This applies to people who have developed cancer as a result of a genetic mutation passed down from their parents.
