In December 2017 researchers from the USA assessed the effect of physical activity on risk of dying from prostate cancer in individuals diagnosed with prostate cancer. 7,328 men who had undertaken physical activity before the diagnosis of non-metastatic prostate cancer and 5,319 after diagnosis were included in the study which lasted for 19 years. Results showed that those undertaking 17.5 hours per week of exercise following diagnosis had a 31% reduced risk of dying from prostate cancer when compared to those undertaking only between 3.5-8.75 hours per week. An analysis appeared to show that the higher the amount of walking undertaken the lower the risk.
