Exercise lowers the risk of prostate cancer

Did you know that exercise lowers the risk of prostate cancer. Avinesh Pursad tells us more.

Prostate cancer is a carcinoma of the prostate gland, found in the male reproductive system. Prostate cancer is the most common cancer diagnosed within the South African male population and, in fact, is the second most common cancer diagnosed in the worldwide male population1,6,9.

Risk factors of prostate cancer

Worryingly, recent research shows  that the incidence of prostate cancer continues to rise in many countries1. It is therefore imperative to know the potential risk factors.

  • Weight: A body mass index (BMI) of <30 is classified as obese, and increases the likelihood of developing prostate cancer1.
  • Diet: No clear links with specific dietary factors have been established although many items, including red meat, dairy, protein, dietary fat, and coffee have been suggested1.
  • Lack of physical activity: Partaking in less than 150 minutes of moderate physical activity per week has been shown to increase the risk1.
  • Genetics: The risk is higher in men who have a first-degree relative with prostate cancer or those under 65 years of age1.
  • Smoking: Research has shown that smoking is associated with a moderate increase in the risk of prostate cancer. Current and/or heavy smokers appear to be at a two-fold or higher risk of prostate cancer1.

Exercise and prostate cancer

Cancer has been associated with a variety of long-term health and psychosocial conditions, thus affected individuals have been described as a very vulnerable population.

Studies have emphasised the importance of health promotion for cancer patients and suggest nutrition, diet, weight management and exercise as possible methods to promote health and reduce the risk factors described3,12. Of these, exercise is arguably the most important as it targets multiple-risk factors of prostate cancer at once9.

Individuals who have survived, or are currently receiving prostate cancer treatment are at a heightened risk of developing secondary malignant diseases and other conditions, including cardiovascular disease, diabetes and osteoporosis, when compared to age- and race-matched populations3,7,10,11,13.

Due to the various prostate cancer treatments and their influence on the human body – causing pain, weakness and fatigue – physical activity appears to be just as important for those suffering from prostate cancer as it is to those at risk of developing prostate cancer8.

In fact, a recent meta-analysis, comprising studies until 2012,   suggests that being physically active is associated with a significant reduction in the risk of prostate cancer9. Furthermore, studies examining physical activity in relation to high-grade prostate cancer and prostate cancer mortality also reported a significant risk reduction9.

Benefits of exercise

Individuals with prostate cancer are shown to have significantly diminished cardiorespiratory fitness8. It is therefore imperative for those with prostate cancer to partake in some form of aerobic exercise, like walking, daily.

Strength exercises are extremely important for functional benefits, such as reducing risk of falling, improving bone health (reduced fractures) and ability to sustain exercise regimes8,10. Strength exercises should incorporate mainly weight-bearing exercises at an intensity that exceeds the average daily load to achieve the desired benefits11.

Pelvic floor muscle strengthening is of particular importance as it may help with urinary and bowel problems that are often associated with prostate cancer. These include incontinence, and leaking bodily fluids when you sit down, cough, sneeze or bend forward. Pilates and yoga classes are two ideal ways of pelvic floor muscle strengthening.

Other benefits of exercise include: a reduction in cancer related fatigue; prevention of sarcopenic obesity; increasing the patient’s chances of completing their full course of treatment and returning to work sooner3,8,11.

Exercise recommendation 

For exercise to be beneficial, it is recommended that strength training should occur two-three days per week, consisting of 30-60 minutes for each session. Strength exercise for prostate cancer patients should include upper and lower body exercises and the use of free weights, weight machines and resistance bands4,5,11,12.

Strength exercises to incorporate in your programme include elastic band rows, squats, lunges, wall push-ups and tricep dips8. It is recommended to perform 15-20 repetitions of each exercise for at least one set to enhance muscle endurance8,9.

Aerobic training should occur three-five days per week of a similar duration to that of the strength training. It should comprise of activities enjoyed the most by the patient to enhance adherence and should make use of lower, trunk and upper movements 2,4,9,11. Additional benefits have also been experienced when aerobic and resistance (strength) training is combined into a training programme7,11.
