摘要
There is a strong negative correlation between prostate cancer and circumcision rate across 181 countries （P〈0.0001）. Adding to the large protective effect of cir- cumcision seen in small studies over the past six decades, a recent large study in Seattle has shown a smaller protective effect. If verified by other large studies else- where, the finding would add to the wide array of benefits conferred by this safe, sim- ple procedure that is best performed in infancy.
