Hey, Man: Want to Cut Your Risk of Prostate Cancer?
Hey, Man: Want to Cut Your Risk of Prostate Cancer?
Sept. 13, 2001 -- Eating a high-fat diet and not exercising have long been thought to increase the chance of getting prostate cancer. Now a new study offers some of the best evidence yet that shows changing your lifestyle is indeed one of the best things you can do to help prevent the No. 2 cancer killer in men, second only to lung cancer.
In the first study, published in the September issue of the Journal of Urology, researchers at UCLA's Jonsson Cancer Center found that eating a low-fat diet and getting regular exercise can slow the growth of prostate cancer by up to 30%.
Each year, roughly 200,000 men in the U.S. are diagnosed with prostate cancer, and about 30,000 men die from the disease.
But the good news is there is mounting evidence that a healthy lifestyle can greatly decrease the chance of getting prostate cancer.
"We have known for a long time that a low-fat, high-fiber diet and exercise may be helpful for men in either preventing prostate cancer or possibly in the treatment of men with prostatecancer," study author William J. Aronson, MD, tells WebMD. But no one has ever directly tested a patient's blood to see how it affects the growth of prostate cancer.
Aronson and colleagues collected blood samples from 13 overweight men. Participants were in their 40s to 70s and said that they normally ate high-fat diets and got little exercise. The men were then put on low-fat, high-fiber diets for 11 days, as well as an exercise routine of walking at a brisk pace for 30 minutes to an hour, four to five times per week.
At the end of the 11-day period, prostate cancer cells were mixed with the men's blood. Then the researchers found that the cancer cells grew 30% slower than before the diet and exercise program.
And when prostate cancer cells were mixed with blood from eight men who had eaten a healthy diet and exercised regularly for more than 14 years, cancer growth slowed by 40% compared to cells mixed with blood from overweight, sedentary men.
