Oesophageal cancer. Light micrograph of the squamous epithelium of the oesophagus showing a squamous cell carcinoma (lower centre). The cancerous cells have large purple nuclei and large amounts of cytoplasm (pale pink). Also seen are several vacuoles containing the protein keratin (dark dots in white areas), produced by the abnormal activity of the cancerous cells. Cancers such as this may lead to difficulty in swallowing. Oesophageal cancer is usually not detected until it has spread to other parts of the body. Magnification: x65 at 35mm size. For healthy oesophageal epithelial cells, see image P510/100.
