Stomach Cancer

      Stomach cancer, also called gastric cancer, is a malignant tumor arising from the lining of the stomach.Stomach cancer may often be cured if it is found and treated at an early stage. Unfortunately, the outlook is poor if the cancer is already at an advanced stage when discovered. In most cases, stomach cancer is found at later stages.


Causes  Of Stomach Cancer


     The exact cause of stomach cancer is unknown, but a number of factors can increase the risk of the disease, including:
  • Gender -- men have more than double the risk of getting stomach cancer than women.
  • Race -- being African-American or Asian may increase your risk.
  • Genetics -- genetic abnormalities and some inherited cancer syndromes may increase your risk.
  • Geography -- stomach cancer is more common in Japan, the former Soviet Union, and parts of Central America and South America.
  • Blood type -- individuals with blood group A may be at increased risk.
  • Advanced age -- stomach cancer occurs more often around ages 70 and 74 in men and women, respectively.
  • Family history of gastric cancer can double or triple the risk of stomach cancer.
  • Lifestyle factors such as smoking, drinking alcohol, and eating a diet low in fruits and vegetables or high in salted, smoked, or nitrate-preserved foods may increase your risk.
  • Helicobacter pylori (H. pylori) infection of the stomach. H. pylori is a bacterium that infects the lining of the stomach and causes chronic inflammation andulcers.
  • Certain health conditions including chronic gastritis, pernicious anemia, gastric polyps, intestinal metaplasia, and prior stomach surgery.
  • Work-related exposure due to coal mining, nickel refining, and rubber and timber processing and asbestos exposure.

Signs and Symptoms of stomach cancer

  • Fatigue
  • Feeling bloated after eating
  • Feeling full after eating small amounts of food
  • Heartburn that is severe and persistent
  • Indigestion that is severe and unrelenting
  • Nausea that is persistent and unexplained
  • Stomach pain
  • Vomiting that is persistent
  • Weight loss that is unintentional





Types of Stomach Cancer 


  • The cells that form the tumor determine the type of stomach cancer. The type of cells in your stomach cancer helps determine your treatment options. Types of stomach cancer include:
  • Cancer that begins in the glandular cells (adenocarcinoma). The glandular cells that line the inside of the stomach secrete a protective layer of mucus to shield the lining of the stomach from the acidic digestive juices. Adenocarcinoma accounts for the great majority of all stomach cancers.
  • Cancer that begins in immune system cells (lymphoma). The walls of the stomach contain a small number of immune system cells that can develop cancer. Lymphoma in the stomach is rare.
  • Cancer that begins in hormone-producing cells (carcinoid cancer). Hormone-producing cells can develop carcinoid cancer. Carcinoid cancer in the stomach is rare.
  • Cancer that begins in nervous system tissues. A gastrointestinal stromal tumor (GIST) begins in specific nervous system cells found in your stomach. GIST is a rare form of stomach cancer.
  • Because the other types of stomach cancer are rare, when people use the term "stomach cancer" they generally are referring to adenocarcinoma.

Stomach Cancer Treatement

Stomach cancer may be treated with the following, in combination, or alone:
  • Surgery, called gastrectomy, to remove all or part of the stomach, as well as some of the tissue surrounding the stomach.
  • Chemotherapy.
  • Radiation therapy.


Precautions For Stomach Cancer

  • Avoid eating spicy food totally.
  • Avoid eating rice
  • Salted, smoked, or nitrate-preserved foods should be completely avoided
  • Have plenty of vegetables and fruits
