Towards the reduction of lung cancer.

The epidemiology of lung cancer clearly demonstrates the preventive opportunities that exist for major causes of cancer death. We have the opportunity to affect lung cancer rates by reducing the effects of smoking. Such activities, in increasing order of importance, include low-yield cigarettes, tobacco smoking cessation and tobacco smoking prevention. Within a community these activities could best be conducted and carried out through a Disease Prevention Unit (DPU), the nature of which is briefly described in this paper.
