The data in this study is more interesting for the size of the effect than for the reduction in metastatic cancer risk in and of itself, as one expects exercise to reduce manifestations of aging across the board, via many direct and indirect mechanisms. Whether the important mechanism in this case, as the researchers suggest, that high intensity exercise consumes metabolic resources that would otherwise be available to tumor tissue, is an open question. It could well be effects on immune surveillance, for example, or any number of other differences in metabolism, such as reduced levels of chronic inflammation, that act to make a less hospitable environment for metastasis.
