Exercise Protects Against Prostate Cancer Death

Exercise&CaP

The Takeaway First

A new study (Bonn et al., 2014) published online in the journal Cancer Epidemiology, Biomarkers & Prevention reported lower rates of all-cause and prostate cancer-specific mortality in men who engaged in regular exercise. Although these findings can’t prove causation, they are a good reminder to move your body with daily physical activity for long-term health – especially after cancer diagnosis.

The Details

  • This study used data from the National Prostate Cancer Register of Sweden Follow-up study.
  • Subjects were 4623 men with localized prostate cancer.
  • Men who biked or walked 20 minutes a day or exercised more than one hour per week had a 26% lower rate of mortality. These men also had significantly lower prostate-specific mortality rates.
  • Even men who did household work for an hour a day had a 29% lower rate of all-cause mortality. (Bonn et al. 2014)

My Take on This

These findings sound familiar, don’t they? That’s because we’ve been hearing this message over and over again from countless sources. And it’s true: exercise can protect against prostate cancer death. The wonderful thing about exercise is that it’s (almost) always an option, and it has extensively documented benefits for your physical and mental health. It does require you to get out of your comfort zone and get moving. Are you up for the challenge?

Despite the stark difference in prognosis between exercising men and sedentary men in this study, it’s important to remember that this study was not a controlled experiment. It was an observational cohort study, which means that all the researchers did was analyze data that were collected without randomly assigning the participants to different groups. But this study does add to the plethora of research linking exercises to less death rates and better quality of life after prostate cancer – here are two most recent studies:

  • Among 2705 men with prostate cancer in the Health Professionals Follow-up Study, those who exercised vigorously for 3 or more hours per week had a 61% lower risk of prostate cancer-specific mortality than those with less than 1 h per week of vigorous activity (Kenfield et al. 2011)
  • Exercise has also been shown to ameliorate the sexual dysfunction of men undergoing androgen deprivation therapy (hormone therapy) for advanced prostate cancer. (Cormie et al. 2013)

Something I found very uplifting that confirmed my experience with prostate cancer patients was the study author’s remark that it is never too late to improve your prognosis by hitting the gym. As Stephanie Bonn says, “physical activity after a prostate cancer diagnosis is beneficial for survival regardless of the patient’s activity level before the diagnosis.” It doesn’t matter whether you were the ripest couch potato or a lean string bean when you got the news. You’re better off the moment you get up and move.

The Bottom Line

This article sounds like good news, and it also sounds like old news. It’s old news because by now we are all familiar with the benefits of exercise. It’s also good news for men with prostate cancer because it shows that simply moving your body on a daily basis decreases the risk of all-cause and prostate cancer-specific mortality. So what is the exercise dose for best benefit? 3 hours a week with moderate intensity movement. You have to sweat. Get your heart rate up. Just a walk in a mall is slightly better than nothing but not optimal. And stay moving after your workout as shown HERE.

    It would appear that there would be a link (by clicking on HERE) to some exercises but there isn’t:

    I agree with exercise but interestingly I belonged to a gym for 2 years prior to PCa diagnosis and did regular circuit training each week and swimming. Also at home squats and push ups every morning . I was fit and muscular. My cancer during this time developed and during the two years my symptoms just got worse and worse until I had to give up the gym and see the doc. Why ?

      You developed CaP way before starting your workout regimen, Dave. It was just found when it was, two-years after you started exercising. Also, a good exercise regimen reduces the risk of death by about 30%. If you add a good nutritional regimen ( and ‘good’ is the tricky part here) it reduces the risk of CaP death another 30%. Good quality and the right type of supplements can reduce risk maybe 10 to 20%. We are up to close to 80% risk cancer death reduction. The remainder 20% or so is luck – 80% are good odds though.
