Fight prostate cancer: exercise
Exercise can play a significant role in fighting prostate cancer. Factors like being inactive, smoking, excess weight, and consuming spicy, fatty and fried foods create an environment that encourages the growth of prostate cancer. Unfortunately, many men with prostate cancer do not prioritize exercise. However, research shows that exercise can extend life, improve quality of life, and slow prostate cancer progression, particularly in men already living with advanced disease.
Several large studies have demonstrated that “exercise can reduce the risk of dying from prostate cancer by 30% and the risk of dying from any cause by 40%,” states UCSF epidemiologist June Chan, and continues, “even brisk walking has shown benefits” in preventing the progression of cancer. Exercise doesn’t directly act on prostate cancer cells but creates an unfavorable environment for their growth. It interrupts the conditions necessary for cancer to thrive. Exercise also impacts hormones like insulin and insulin-like growth factor that may be involved in cancer development.
A study called the ERASE trial (published in JAMA Oncology in 2021) examined the effects of high-intensity interval training on men with early-stage prostate cancer and found that exercise decreased PSA levels and slowed PSA velocity, which are indicators of cancer progression. Cardiovascular health is crucial for men with prostate cancer. Exercise can improve cardiorespiratory fitness and overall well-being. “Cardiovascular disease is a major cause of illness and death for patients with prostate cancer,” states Harvard epidemiologist Lorelei Mucci, Sc.D.
Further research is needed to understand the full effects of exercise on prostate cancer at different stages. However, the existing evidence suggests that exercise prolongs life, lowers the risk of dying from prostate cancer and heart disease, and offers numerous benefits. Even moderate exercise can make a significant difference, so there’s no need to engage in intense workouts to reap the benefits.
