Lakoski SG, et al "Cardiorespiratory fitness and risk of cancer incidence and cause-specific mortality following a cancer diagnosis in men: The Cooper Center longitudinal study" ASCO 2013; Abstract 1520.
The risk of developing and dying from two types of cancer was recently shown to be reduced by high levels of cardiovascular fitness in a study presented at a press conference prior to the 2013 American Society of clinical oncology annual meeting. The study conducted by Susan Lakoski, M.D. involved more than 17,000 men over a 20 year span with a mean age of 50 years. A comparison was made between different levels of cardiovascular fitness. Comparing the men with the highest level of fitness compared to those with the lowest level of fitness the risk of lung cancer was reduced by 68%. For colorectal cancer the risk reduction was 38%. Even a small improvement in fitness level resulted in a 14% reduction in the risk of death by cancer and a 23% reduction in risk of dying from cardiovascular disease. While the study could not establish a cause-and-effect between fitness and cancer risk, the association between the two was unmistakable.
