It is reported ' Reporter Wang XueFei) Peking University clinical the intersection of tumour and the intersection of institute and ring Li,etc. research and propose, in the male crowd in China, peculiar antigen (PSA) of prostate while acting as the blood Higher than 10ng/ml or rectum and refer to examining while touching prostate tubercle, just proposes paying the prostate to puncture and check. This result of study is published on " China's medical magazine " recently.
