								Carruthers MR publish a study on the 
								detection of  prostate cancer in 1365 men (old 
								from 28 to 87 years -average age 55 years) 
								treated continuously with androgens for one 
								period going back sometimes to 20 years. They 
								concluded that the monitoring of the prostate 
								under continuous treatment with androgens is 
								safe and improves early detection of prostate 
								cancer whose frequency is the same one as in the 
								whole of the population.
