Blocking male hormone (androgen ablation therapy) is used to treat prostate cancer.

Asian populations are at high risk of developing type 2 diabetes (T2D). In this study scientists from Vanderbilt Institute for Medicine and Public Health in Nashville and from research institutes in Shanghai examined the intake of either fruits or vegetables and any protective effect that may lower the incidence of T2D in women. Data was collected on 64,191 women with no history of T2D or other chronic disease at the start of the study.
