Stomach cancer has many causes. Radiation exposure, bacterial infection caused by Helicobacter pylori, pernicious anemia, abdominal surgery, as well as genetic factors.
Helicobacter pylori infection is currently considered responsible for most of the cases involving cancer.
However, gastric cancer between the esophagus and stomach are not associated with Helicobacter pylori infection.
Symptoms of stomach cancer because of stomach capacity and the presence of a tumor is not curable at the time of diagnosis.
This is the biggest cause of why patients who have tumors in the stomach in severe circumstances can not be cured.
In America low stomach cancer patients is different in other countries such as the far east. In the far east are very high incidence of gastric cancer, could be due to Helicobacter pylori infection and certain foods. Helicobacter pylori is known as a carcinogen and is known and the cause of stomach cancer, but may also have other causes besides Helicobacter pylori.
Some causes of stomach cancer could be the underlying disease or condition, including some types of cancer. There may be environmental reasons such as chemical exposure or too much inhaling fumigants, untreated infections and also a diet that is not true.
Stomach cancer is usually found in a place where the stomach lining is irritated and infected. Some health experts argue that this cancer because of infection, and while others think that cancer is caused by infection.
Several studies have also shown that stomach cancer can be caused by the wound in the abdomen. developing stomach polyps can also cause cancer polyps are considered precursors to cancer. If certain polyps to grow more than three-quarter inch, then chances are, it will cause stomach cancer.
Some other conditions that cause stomach cancer such as anemia, gastrectomy surgery where the stomach is removed, and stomach disease which is known as atrophic gastritis. Even exposure to mold, smoke and some constant gas can cause stomach cancer. Diets containing high amounts of salt and preservatives can also cause stomach cancer.
So, for those of you who are on a diet, check your diet.
Chronic infection with Helicobacter pylori in some susceptible individuals cause changes in the lining of the stomach resembling small intestine (intestinal metaplasia). Risk of stomach cancer after obtaining intestinal metaplasia in the stomach is not nearly as great as seen with Barrett's esophagus (precancerous condition of the esophagus). Therefore, it is not currently recommended that patients with precancerous changes in the stomach into endoscoped regularly. However, it is recommended that patients have endoscopy every five to ten years after finding intestinal metaplasia.
So anyone who has many family members with gastric cancer should be examined for Helicobacter pylori infection and several endoscopy screening in this situation. Stomach cancer can spread to family members, because family members are genetically susceptible to the disease or because family members have been infected with Helicobacter pylori each other. So if you have family with cancer, get used to this early detection of stomach cancer.
