Following AICR Recommendations to Prevent Aggressive Prostate Cancer
A new study suggests that men have a lower risk of developing an aggressive form of prostate cancer by following at least four of AICR recommendations for cancer prevention, including eating healthy and exercising, with each recommendation lowering the risk. The study is scheduled to be published online ahead of print in the journal Nutrition and Cancer.
For the study, researchers gathered the diet and activity habits of approximately 2,200 men ages 40 to 70. All the men had recently been diagnosed with an aggressive form of prostate cancer.
The researchers used a point scale to gauge how closely the men adhered to the 8 relevant AICR recommendations for cancer prevention. For example, men who were moderately active for 60 minutes or more each day were given a score of one; those who were moderately active 30 to 60 minutes a day had a score of 0.5; and those who were the least active were assigned a 0. AICR has 10 recommendations; the two that were not looked at related to breastfeeding and for cancer survivors to follow the other recommendations.
Adherence to fewer than four of the eight recommendations predicted a 38 percent increased risk of aggressive tumors compared with adherence to four or more recommendations. The finding applied to both black and white men, despite the higher risk of highly aggressive tumors among black men. Each point in a patient's total adherence score linked to a 13 percent reduction in risk of aggressive cancer.
AICR’s report and its continuous updates show that eating a diet high in tomatoes, watermelon and other foods containing lycopene reduce the risk of prostate cancer. A diet high in mushrooms and other foods containing selenium also lowers the risk.
