A new study suggests your fitness level may affect your risk of certain cancers.

Researchers from Johns Hopkins School of Medicine tracked nearly 50,000 adults who took a treadmill stress test. Those who were very fit were 77 percent less likely to develop lung cancer, and 61 percent were less likely to develop colorectal cancer than the least fit.

And fit people who did develop one of these cancers had a lower risk of dying from the disease.
