Researchers at City of Hope ® , one of the largest and most advanced cancer research and treatment organizations in the United States, ranked among the nation's top 5 cancer centers by U.S. News & World Report and a national leader in providing cancer patients with best-in-class, integrated supportive care programs, now understand why taking an investigational white button mushroom supplement shows promise in slowing and even preventing prostate cancer from spreading among men who joined a phase 2 clinical trial studying "food as medicine.

" Looking at preclinical and preliminary human data, the City of Hope scientists found that taking white button mushroom pills reduces a class of immune cells called myeloid-derived suppressor cells (MDSCs), which has been linked to cancer development and spread. "City of Hope researchers are investigating foods like white button mushroom, grape seed extract, pomegranate, blueberries and ripe purple berries called Jamun for their potential medicinal properties. We're finding that plant-derived substances may one day be used to support traditional cancer treatment and prevention practices," said Shiuan Chen, Ph.
