Techniques in intervention against carcinogenic hazards

The principal techniques for the control of carcinogenic hazards are described. A sense of responsibility must be encouraged in the groups of people who are involved, such as manufacturers, importers, retailers or distributers. Relevant, evaluated information from the scientific community must be brought to the attention of responsible bodies in a systematic way. Information about sources of emission, pathways of spread and identification of populations at risk is essential. Estimates must be made of costs and benefits, whether tangible or intangible. Mechanisms of intervention are described, including registration, authorization, permission, notification and dissemination of information. Mechanisms of risk surveillance involve the monitoring of health indices and of exposure situations: techniques of data collection are outlined. It is important that such data be both accessible for evaluation by authorized persons and at the same time remain confidential. Education is basic to cancer prevention. National and international coordination is essential. The paper concludes with a list of areas in which strategies and techniques should be developed.
