Important information about Stomach Cancer

Short video with important information:

What is stomach cancer?

Stomach cancer happens when malignant cells, cancerous cells arise in the stomach. To determine which type of stomach cancer a person has, a specialized gastroenterologist has to determine which types of cells and which part of the stomach is involved. Depending on the cells and part of the stomach affected, the cancer is classified as adenocarcinoma, lymphoma, carcinoid tumor or leiomyosarcoma.

People with an infection known as H. pylori can often get stomach cancer. Helicobacter pylori, or H. pylori, is a bacterium that attacks your stomach and intestines. As H. pylori bacteria attack the lining of your stomach, they secrete an enzyme that neutralizes stomach acid. On top of being the most common cause of gastritis and stomach ulcers, H. pylori is the primary cause of stomach and gastric cancer.1.


Once stomach cancer causes signs and symptoms, they may include:

  • Unintentional weight loss
  • Fatigue
  • Trouble swallowing
  • Feeling bloated especially after eating
  • Stomach pain, especially in the upper stomach
  • Nausea
  • Having no appetite or feeling full after eating a small amount of food
  • Severe heartburn
  • Severe indigestion
  • Vomiting (hematemesis)
  • Feeling tired and short of breath, typically due to anemia (a condition when people have too few red blood cells)
  • Melena (black stool)


There are many causes of stomach cancer. Stomach cancer occurs more commonly in men than women. Estrogen may be a factor to protect women from the development of this cancer. In most cases, it is caused by H. pylori. When the immune system detects the damage caused by H. pylori, it causes an inflammatory response within the gastric lining, causing gastritis. As long as H. pylori remains in the stomach, it continues damage and inflammation persists, leading to chronic gastritis. 

Other risk factors for stomach cancer are GERD and obesity. Factors that increase your risk of stomach cancer are:

  • Smoking
  • Alcohol consumption
  • Stomach polyps
  • Long-term stomach inflammation
  • Anemia
  • AIDS
  • Family history of stomach cancer
  • Eating salty foods
  • Not eating enough fruits and vegetables
  • Type A blood


Diagnosis of stomach cancer is essentially made with:

  • Upper endoscopy, a procedure when a tube with a camera at the end of it is placed into the stomach to visualize the tumor and take a biopsy. 
  • Biopsy, a small sample of tissue is taken from the irritated area of the stomach and then analyzed under a microscope.
  • X-rays with barium contrast of the upper GI tract is used to identify complications like ulcers, Abdominalpelvic CT scan is used to evaluate if the cancer has spread to nearby organs or lymphnodes in order to determine the stage of the tumor. 
  • Blood tests


For initial stages, surgery can be performed to treat your cancer. For advanced stages, surgery can only relieve pain. Chemoradiotherapy post-surgery is used to increase the rate of survival. Unfortunately stomach cancer is usually diagnosed at very advanced stages. 

Stomach cancer is usually treated with one or more of the following:

  • Surgery to remove the stomach cancer, the doctor may remove all or part of your stomach
  • Chemotherapy to kill cancer cells or stop them from growing. It is possible for a person to undergo chemotherapy prior to surgery.
  • Radiation therapy to kill cancer cells.
  • Immunotherapy, a term used for medicines that to stop cancer growth.
