I get mixed feelings whenever I see one of these reports. It's nice to get more data in the fight against cancer but it doesn't look like any progress in directly attacking cancer. And there's doubt about the data too. I wonder about how much money and effort is going into such studies which is not being invested into novel techniques for attacking cancer.
You could do cardiovascular exercise which, in theory, might possibly have a beneficial reduction in personal cancer rates (among many other potential health benefits attributed to persistent exercise). Or you could not do cardio.
