There is limited data on the relationship between cardiorespiratory fitness and lung and colorectal cancer risk and mortality.

To investigate, Catherine Handy Marshall, MD, MPH, of Johns Hopkins School of Medicine, and her colleagues studied 49,143 adults who underwent exercise stress testing from 1991-2009 and were followed for a median of 7.7 years.

The study represents the largest of its kind, as well as the first of its kind to involve women and a large percentage of non-white individuals. Those in the highest fitness category had a 77 percent decreased risk of developing lung cancer and a 61 percent decreased risk of developing colorectal cancer.

Among individuals who developed lung cancer, those with the highest fitness had a 44 percent decreased risk of dying during follow-up, and among adults who developed colorectal cancer, those with the highest fitness had an 89 percent decreased risk. "Our findings are one of the first, largest, and most diverse cohorts to look at the impact of fitness on cancer outcomes," said Dr. Handy Marshall.

"Fitness testing is commonly done today for many people in conjunction with their doctors. Many people might already have these results and can be informed about the association of fitness with cancer risk in addition to what fitness levels mean for other conditions, like heart disease."

Additional studies are needed to expand on these results and to determine if improving fitness can influence risk and mortality rates of cancer
