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.
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.
