Prostate biopsy is not always necessaryScientists at Wake Forest University School of Medicine and the University of Wisconsin-Madison have discovered that some elevated prostate-specific antigen (PSA) levels in men appears to be caused by a hormone normally occurring in the body, and are not necessarily a predictor of the need for a prostate biopsy.
Elevated levels of PSA have traditionally been seen as a potential sign of prostate cancer, leading to the widespread use of PSA........Go to the Prostate-cancer-blog (Added on 11/9/2009 8:22:43 AM)
