Physical activity and cancer etiology: associations and mechanisms

McTiernan, Anne, Ulrich, Cornelia, Slate, Shelley, Potter, John·1998·Cancer Causes & Control

Abstract

Objectives This paper reviews the epidemiologic data of associations between physical activity and cancer risk, describes potential mechanisms for a physical activity cancer link, and proposes future directions for research.Methods We reviewed English-language published papers on physical activity and cancer through Medline searches for epidemiologic studies, and through references on individual reports. We reviewed general texts on effects of exercise on human biology and applied the concepts to the biology of cancer in humans to describe potential mechanisms for a physical activity-cancer association.Results Considerable epidemiologic evidence has accrued linking increased physical activity with reduced occurrence of cancers of the breast and colon. The association between physical activity and cancers of other sites is unclear. Potential mechanisms for the association between physical activity and reduced risk for breast and colon cancer are varied: they range from bias due to physical activity's strong correlations with other health factors (e.g., diet, smoking, alcohol use, use of medications) to the metabolic effects resulting from increased physical activity and fitness, such as reduced obesity, hormonal and reproductive effects, mechanical effects, and enhancement of the immune system.Conclusions The elucidation of biologic mechanisms for an association between physical activity and cancer may provide biological support for the association. It will contribute information to determine the type, frequency, and duration of exercise needed to maximize protection. This information will be needed before large-scale community interventions are begun, in order to choose the correct interventions for the desired effect of reduced incidence of the most common cancers.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
