Vocal cord cancer cells. Light micrograph of cells from an epidermoid carcinoma of the vocal cords. The cells have been stained, with the cancerous cells being the large, irregular pink cells. Cancer cells proliferate faster than normal cells, leading to the growth of malignant tumours and, in many cases, death. Treatment is by surgical removal, and radiotherapy or chemotherapy to kill any remaining cells. A carcinoma forms from epithelial tissue, a tissue type found in skin and on the internal surfaces such as the respiratory and digestive tracts. Magnification: x885 when printed 10 centimetres tall.
