The laser in British hospitals. A. While military scientists test lasers against satellites, surgeons use them as miraculously accurate scalpels. The beam can be focused to spot one fiftieth the size of a human hair: yet its intensity is enough to kill cancer cells or drill though the most delicate bones. B. For cancer treatment, the disease cells must be killed while their healthy neighbours are left unharmed. Where the cancer can be directly and accurately attacked, laser treatment does well. For cancers that are less accessible, there is a new and potentially valuable technique in which the patient is injected with a chemical that then attaches itself preferentially to cancer cells. When the laser strikes the chemical, it releases a form of oxygen that kills these cells. C. Furthermore, the laser beam can also remove bone and so it is invaluable in ear surgery. The sounds we hear are carried from the eardrum to the nerves of the ear by a delicate set of small bones which sometimes solidify causing deafness. A laser vaporises the bone without touching any of the surrounding tissue. D. Birthmarks, once almost untreatable, are a mass of blood vessels and being red, they absorb the laser beam strongly. It seals them so that the mark becomes less conspicuous. The normal cells on the skin’s surface, which don’t absorb much of laser beam, act in the healing and help to conceal the mark. The operation can transform the lives of people who had to suffer from lifetime physical abnormalities. E. Some ten new centres already using this treatment will soon be opened in Britain, which is already one of the leaders in the laser treatment of bleeding peptic ulcers and this, combined with medicines, can mean ulcer treatment without conventional surgery.
