Men diagnosed with low-risk prostate cancer may opt for active surveillance, in which they are carefully monitored in lieu of initial treatments. A study in JAMA Oncology suggests such men may be able to help avoid progression of low-risk prostate cancer to more dangerous stages by adopting a healthy diet. Johns Hopkins researchers began collecting information on men with prostate cancer twenty years ago. This may be the first study to provide significant evidence a healthy diet is associated with a reduction in risk of the cancer progressing to a more aggressive grade. For patients adhering to a high-quality, low inflammation diet, every twelve points improvement in the diet score resulted in a fifteen percent lower chance of progressing to a more aggressive cancer.
