How is stomach cancer diagnosed?

When a doctor suspects stomach cancer from the symptoms described by the patient, he or she will use several methods to find out if the disease is present. A complete medical history will be taken to check for any risk factors. A thorough physical examination will be conducted to assess all the symptoms. Laboratory tests may be ordered to check for blood in the stool

(fecal occult blood test) and anemia (low red blood cell count), which often accompany gastric cancer.

Endoscopy is the most important investigation. This should be done promptly in patients with dyspepsia which persists for more than a few weeks or which does not respond to treatment, especially in those over the age of 40-45 years. At endoscopy the inner lining (mucosa) can be carefully inspected and biopsies of any suspicious or abnormal areas can be taken. Sometimes it is not possible to tell whether a gastric ulcer is benign or malignant from the appearances alone and multiple biopsies are usually needed. All patients with a gastric ulcer which is thought to be benign should undergo a repeat examination four to six weeks after treatment to ensure that the ulcer has healed properly.

Once the pathologist has confirmed the diagnosis of cancer further investigations are then carried out to asses whether the tumor has spread through the wall of the stomach to involve adjacent organs and to asses whether or not there is spread of the disease to the liver. This "staging" is necessary to determine whether the tumor can be removed surgically or not. A CT scan is the most important investigation for this and usually gives accurate information but occasionally tiny deposits of tumor have spread (like seeds) thoughout the abdomen and are not visible on the CT scan. For this reason surgeons sometimes wish to perform laparoscopy before deciding whether or not to operate. In this technique the patient is given brief general anesthetic and the surgeon inspects the abdominal cavity carefully with a telescope which is passed through a small incision in the abdominal wall.
