Estimating avoidable causes of cancer.
Evidence that much cancer is preventable derives from observations of time trends and geographic patterns of cancer, birth cohort changes, high risks in groups with well-defined exposures, and experimental studies. In an effort to identify additional opportunities for reducing the impact of cancer on society, this conference assessed avoidable causes of cancer. The magnitude and extent of preventable causes of cancer are subjects of intense debate, with discrepancies often related to the use of different time frames and different weights for epidemiologic and toxicologic evidence. There is much agreement, however, about the exposures that increase risk, notably tobacco, alcohol, diet, radiation, medications, occupational exposures, general environmental exposures, and infectious agents. Interactions between carcinogenic exposures and genetic susceptibility are also important. Concerted efforts are needed to identify avoidable causes of cancer and to apply knowledge already obtained to reduce the cancer burden.
