Stomach cancer: Introduction
Stomach cancer is an uncontrolled growth of abnormal cells in the lining of the stomach. Stomach cancer is also celled gastric cancer. Stomach cancer is common type of cancer and one of the top ten cancer killers.
Stomach cancer is most curable if caught in the earliest stages of the disease. Untreated and/or advanced stomach cancer can grow and spread to other parts of the body, such as the lymphatic system and the pancreas and liver, and eventually become terminal.
People at risk for developing stomach cancer include those who smoke and older adults. People who have an infection of the bacterium Helicobacter pylori, the bacterium that also causes stomach inflammation and peptic ulcers, are also at risk for stomach cancer. Other diseases that cause long-term inflammation of the stomach, such as pernicious anemia, can increase the chances of developing stomach cancer.
Other risk factors for stomach cancer include having a family history of stomach cancer and eating a diet high in fat and salted, pickled, and/or smoked foods. Being obese and having a sedentary lifestyle that is sedentary are also risk factors for stomach cancer.
In early stages of stomach of cancer, there are often no symptoms. If there are symptoms, they can be very vague and include indigestion and loss of appetite. As stomach cancer progress, other symptoms appear. These include vomiting blood (hematemesis) and having black, tarry stools or frank blood in the stool (melana). Complications of stomach cancer can be life-threatening. For more information on complications and symptoms, refer to symptoms of stomach cancer.
Diagnosing stomach cancer and it stage of advancement begins with taking a thorough personal and family medical history, including symptoms and risk factors for stomach cancer. Diagnosis also includes completing a physical examination.
Diagnostic testing includes an endoscopy procedure. In this procedure, the physician examines the esophagus and stomach by inserting a flexible lighted instrument through the mouth and throat and down into the esophagus and stomach. This instrument, called an endoscope, takes pictures of and/or sends images to a computer monitor.
A biopsy may also be taken during the endoscopy. A biopsy involves taking a small sample of stomach tissue to examine under a microscope for the presence of cancer cells.
A stool sample may be tested to determine if there is blood in the stool. Testing generally also includes a complete blood count, which can determine if anemia is present due to bleeding from inside the stomach. In addition, blood tests may also be done to test for a Helicobacter pylori infection, a risk factor for the development of stomach cancer.
A diagnosis of stomach cancer can be missed or delayed because there may be no symptoms in early stages of the disease. Additionally, some symptoms are similar to those of other conditions, such as peptic ulcer or indigestion. For more information on misdiagnosis, refer to misdiagnosis of stomach cancer.
Treatment of stomach cancer varies, depending on the stage of advancement of the disease and other factors. Treatment generally requires a combination of surgery, chemotherapy, and radiation therapy. For more information on treatment, refer to treatment of stomach cancer. ...more »
