Prostate cancer odds slashed by healthy living, new study suggests.
Over 27 years, just over 3,000 men developed prostate cancer, and 435 died from it. Genes made a big difference: Men with genetic risk scores in the top 25% were over four times more likely to die of the disease, versus those in the bottom 25%, the investigators found.
But for those same men, lifestyle also had a big impact. Those who stuck with at least four of the six healthy lifestyle factors cut their odds of dying from prostate cancer by 45%, versus men who adhered to few or none.seemed most important, followed by maintaining a healthy weight. The findings do not prove that those healthy habits, per se, saved some men's lives. But Dr. William Dahut, chief scientific officer at the ACS, called the results "encouraging."
"What's interesting is this suggests that a healthy lifestyle may not decrease your risk of developing prostate cancer, but may decrease your risk of lethal prostate cancer — which is much more important," said Dahut, who was not involved in the study., but both doctors said that could change in the coming years.
For now, men can get some sense of their genetic risk based on family history, though that's not the whole story, Dahut said. Having a father or brother with prostate cancer more than doubles a man's risk of developing the disease, according to the ACS.
