To cut their risk of dying from prostate cancer, men should consider adopting six healthy living habits that include eating more tomatoes and fatty fish, a new study suggests.
Researchers found that men who followed five to six of the habits had a 39% lower risk of dying from prostate cancer compared to people who adopted none or only one. Researchers arrived at these impressive results by examining 25 years of data from nearly 46,000 men. The six habits were eating fatty fish, eating more tomatoes, reducing intake of processed red meats, not smoking, maintaining a body mass index less than 30 and exercising.
A similar study that included more than 21,000 men found that these lifestyle changes had an even larger effect on mortality risk, making men 47% less likely to die from the common cancer. Men who adopted only the dietary changes had a 27% lower risk of developing lethal prostate cancer.
One in six men will be diagnosed with prostate cancer in his lifetime, making it the most common cancer in men behind skin cancer. However, because many prostate cancers are slow-growing or appear late in life, many men with the disease will not die from it.
While each of these habits individually had previously been shown to help protect against prostate cancer, this was the first study of their cumulative effect. Researchers are now exploring which of these interventions most dramatically cuts prostate cancer risk.
