A new study published in the journal Cancer Epidemiology, Biomarkers & Prevention has suggested that men who already have localized prostate cancer could reduce their risk of all-cause and prostate cancer-specific mortality simply by exercising more.
Previous study have documented that physical activity reduces prostate cancer. Few studies have investigated the impact of exercise following a cancer diagnosis.
The research team analyzed the data of 4,623 men who were a part of the National Prostate Cancer Register of Sweden Follow-up Study.
The results of the analysis revealed that men exercised for 20 minutes each day, by either walking or cycling, were 30% less likely to die from any cause and 39% less likely to die from prostate cancer, compared with men who walked or cycled less than 20 minutes a day.
What is more, the team found that men who engaged in physical activity for at least 1 hour a week were at 26% lower risk of all-cause mortality and 32% lower risk of prostate cancer-specific mortality, compared with those who exercised for less than 1 hour each week.
“Our results extend the known benefits of physical activity to include prostate cancer-specific survival, said Stephanie Bonn of the Department of Medical Epidemiology and Biostatistics at the Karolinska Institutet in Sweden. However, it is important to remember that our results are on a group level. An individual’s survival depends on many factors, but physical activity is one factor that individuals can modify. Hopefully, our study can motivate men to be physically active even after a prostate cancer diagnosis.”
