Gretchen Reynolds of The New York Times describes a small study from researchers at the University of Queensland in Brisbane, Australia. The study recruited 20 men who had survived colon cancer. The men completed either a single workout or a 1-month workout regime (stationary bike interval training). The researchers drew blood from each group at various points in time and added some of the men’s blood to petri dishes with human colon cancer tumor cells. The scientists then counted the numbers of cells in each dish.
In the dishes containing fluid taken from the men immediately after a single workout, the scientists counted far fewer cancer cells…There was no similar decline in the dishes from the men who had trained for a month. In effect, something about the blood drawn immediately after the workout was slowing the growth of cancer cells.
The researchers…found a large increase in molecules involved in inflammation immediately after exercise. Inflammation can slow cell growth and reproduction. So a transitory increase in inflammatory markers after exercise might be helping to jam the proliferation of tumor cells…
