The doctor may also look inside the stomach with a thin, lighted tube called a gastroscope. For this test, the gastroscope is inserted through the mouth and guided into the stomach. If the doctor sees tissue that is not normal, he or she may cut out a small piece so it can be examined under a microscope to see if there are any cancer cells. This procedure, called a biopsy, is the only way to confirm the presence of cancer cells. It is usually done during the gastroscopy.
Stomach cancer is curable if it is found before it has spread.
Once it has spread to the lymph nodes or other organs, however, it is much more difficult to treat.
