Test for stomach cancer. Gastroscope view of a sample of tissue being nipped off the inside stomach wall to check for signs of stomach cancer. This routine test is carried out on patients suspected of having a malignant tumour in the stomach. A gastroscope - a fibre-optic viewing device - is inserted into the stomach through the mouth and oesophagus. Forceps attached to the gastroscope are used to take a tissue sample for biopsy (microscope examination). Stomach cancer is most common in the elderly and in males, and is particularly common in Japan. Treatment involves surgical removal of part or all of the stomach.
