There is by now a long list of proven occupational cancer risks; these cover a wide range of jobs and carcinogenic substances, and a variety of cancer sites. One occupational cancer recently brought to light, where the exact agent is not yet known, is carcinoma of the nasal cavity and accessory sinuses in woodworkers. Acheson, Hadfield and Macbeth (1967) examined the incidence of this cancer in men in Oxfordshire and parts of Berkshire and Buckinghamshire and found that from 1956 to 1965, there had been 17 cases among some 12000 woodworkers, although not more than one case would have been expected according to regional age-specific rates. The excess of cases was among furniture workers in High Wycombe. Intensive work is currently being carried out on the cancer mortality of a number of occupational groups including asbestos workers and rubber workers. But there are various suspected occupational cancer risks which still await investigation, and which an industrial medical officer may be well placed to study. For instance, it has long been suspected that metal dust can cause cancer of the larynx, but it seems that nobody has yet taken a group of men with past exposure of this kind and made a survey of their subsequent cancer mortality.
