Causes Of Stomach Cancer

Doctors are not sure what causes stomach cancer. There is a strong correlation between a diet high in smoked foods, salted and pickled foods and stomach cancer. As the use of refrigeration for food preservation has increased throughout the world, stomach cancer rates have declined.

In general, cancer begins an error (mutation) occurs in the DNA of the cell. The mutation causes the cell to grow and divide rapidly, and to continue to live in normal cells would die. Accumulates in tumor cells form a tumor that can invade nearby structures. And the cancer cells can break away from the tumor to spread throughout the body.

Stomach cancers

The cells that make up the type of cancer of stomach cancer. Depending on the type of stomach cancer cells to help determine treatment options. Types of stomach cancer are:

Cancer that begins in glandular cells (adenocarcinomas). The glandular cells that line the inside of the stomach secretes a protective layer of mucus that protects the stomach lining of acidic gastric juice. Adenocarcinoma accounts for the vast majority of all cancers of the stomach.

Cancer that begins in cells of the immune system (lymphomas). The walls of the stomach contains a small number of immune system cells that can develop cancer. Lymphoma of the stomach is rare.

The cancer that begins in cells that produce hormones (carcinoid tumor). The hormone-producing cells can develop into cancer carcinoid. Carcinoid tumor of the stomach is rare.

Cancer that begins in the tissues of the nervous system. A gastrointestinal stromal tumor (GIST) begins in certain nerve cells in the stomach. GIST is a rare type of stomach cancer.

Because other types of stomach cancer are uncommon, when people use the "stomach cancer", a term that generally refers to an adenocarcinoma.
