A high level of cardiorespiratory fitness (CRF) dramatically reduces the risk of getting lung and colorectal cancer (CRC) and significantly increases survival rates. In one of the most diverse retrospective cohort studies, researchers analyzed data from over 49,000 participants with a median age of 54 years. Those with the highest CRF levels (>12 METs, measured using a treadmill stress test) possessed a 77% lower risk of lung cancer and a 61% lower risk of CRC than those with the lowest fitness levels (<6 METs). Participants diagnosed with cancer who were in the highest CRF range prior to diagnosis also saw great benefits. Following diagnosis, those with lung cancer had a 44% lower risk of all-cause mortality and those with CRC, an 89% lower risk, compared to those who were less fit. American Cancer Society Takeaway: Researchers who conducted the study believe that these results act as some of the strongest evidence…
