Prevention measures key to reducing cancer.

In China, a programme helped install 129 million new stoves in rural homes between 1982 and 1992. A subsequent evaluation showed around a 40% reduction in lung cancer which was associated with using cleaner coal stoves with chimneys instead of traditional open coal fires.

This is an example of how using primary prevention measures that eliminate or decrease exposure to environmental carcinogens, including in occupational settings, is key to reducing the incidence of cancer.
