Circumcision cuts prostate cancer risk

Men who are circumcised before becoming sexually active face a decreased risk of developing prostate cancer, research finds.

In a study of 3400 men, US researchers showed those circumcised before first sexual intercourse were 15% less likely to develop prostate cancer compared with uncircumcised men.

Writing in Cancer, the authors said their findings supported the involvement of infectious or inflammatory pathways in prostate carcinogenesis.
