Screening asymptomatic men for prostate cancer: A comparison of international guidelines on prostate-specific antigen testing.

Population screening of asymptomatic men is not widely recommended. Instead, balancing the potential harms and benefits of PSA testing is endorsed.

The development of clinical decision aids and international consensus on guidelines may help reduce national and international variation on how men are counselled.
