Lifestyle and Prostate Cancer

According to a study published in The Journal of Urology, progression of early, low-grade prostate cancer may be slowed if men make healthful changes to their diet, physical activity level, and stress management techniques.

The prostate is a gland of the male reproductive system. It produces some of the fluid that transports sperm during ejaculation. After skin cancer, prostate cancer is the most common form of cancer diagnosed in men. Current treatment options include watchful waiting (delay of treatment until signs of cancer progression), surgery, chemotherapy, radiation, and/or hormonal therapy. A blood test that is often used to screen for prostate cancer or to monitor patients after prostate cancer treatment is the prostate specific antigen (PSA) test. For men who have already been diagnosed with prostate cancer, an increase in PSA level may indicate cancer progression or recurrence.

To evaluate the effect of intensive lifestyle changes on PSA levels in men with untreated prostate cancer, researchers conducted a randomized clinical trial among 93 patients. All patients had low-grade prostate cancer (Gleason score less than 7), initial PSA levels between 4 and 10 ng/ml, and early-stage cancer (T1 or T2). All of the patients had chosen not to undergo conventional treatment for prostate cancer. Half the patients were assigned to receive the lifestyle intervention and half were asked to follow the advice of their physician regarding lifestyle changes.

Men in the lifestyle intervention group were given the following instructions regarding diet, physical activity, and stress management:

  • A prescribed diet consisting primarily of fruits and vegetables, whole grains, legumes, and soy products

  • A recommended level of physical activity of 30 minutes of moderate aerobic activity six days per week

  • Stress reduction techniques that included stretching, breathing, meditation, imagery, and progressive relaxation for a total of one hour per day

These men also attended a support group once a week to help them stick with the program.

After one year, 95% of the men in the intervention group were still adhering to the study
