My urologist kept affirming that because I am an avid yoga practitioner that my recovery from bladder, kidney tumors and prostate cancer was better than what he normally sees. Now research is showing this to be true. Higher recreational physical activity levels before and after diagnosis improves prognosis in men diagnosed with non-metastatic prostate cancer.
A paper published in the American Association for Cancer Research (AARC) examined the the associations of pre- and post-diagnostic recreational physical activity, and sitting time with prostate cancer specific mortality (PCSM) among men diagnosed with non-metastatic prostate cancer.
They looked at 10,067 men who were diagnosed with non-metastatic prostate cancer between enrollment in 1992 or 1993 and June 2011, of whom 600 died of prostate cancer during follow-up through 2012. Multivariable-adjusted Cox proportional hazards regression models were used to calculate hazard ratios (HRs) and 95% confidence intervals (CIs) for the associations of self-reported pre-diagnostic and post-diagnostic physical activity and sitting time with PCSM.
The Results – Compared with low hours per week of recreational physical activity, the equivalent to 5 hours of walking per week was associated with 30% lower risk of PCSM for pre-diagnostic, and with 34% lower risk for post-diagnostic recreational physical activity. Among men with walking as the only form of leisure time physical activity, walking 4 hours or more per week before diagnosis was associated with lower risk of PCSM, while no statistically significant association was observed with walking after diagnosis. Sitting time was not associated with PCSM.
They concluded that higher recreational physical activity levels before and after diagnosis may improve prognosis in men diagnosed with non-metastatic prostate cancer. These results add support that prostate cancer survivors should adhere to physical activity guidelines and that physicians should promote adopting a physically active lifestyle to prostate cancer survivors. So join me in doing some yoga, men!
