Stomach cancer. Coloured frontal X-ray of a cancerous (malignant) tumour (dark, centre) in a patient's stomach. Sections of the gut show up as white because a radio-opaque barium meal was given prior to the X-ray. This highlights the structure of the gut. Any narrowing or obstructions, such as the cancer shown here, prevent the passage of the barium meal. They therefore do not show as white, allowing their location to be pinpointed.
