Prostate Cancer Often Starts When a Man Reaches His Fifties
Almost 10 Years to Till Detectable By Current Methods

Researchers at the Department of Veterans Affairs believe a substantial portion of prostate cancer develops in men in their early 50's, although the disease is not diagnosed until 6.6 to 10 years later. They say this information is important to developing optimal approaches to PSA screening for prostate cancer as men age.
     Prostate cancer takes almost ten years to reach clinically detectable size, the researchers say. As part of a 30-year study of 2,200 men as they age, PSA tests were taken from 97 participants who had prostate cancer, and from 281 participants with benign prostatic hyperplasia (BPH) or enlarged prostate. The average age at which prostate cancer became clinically detectable ranged from 49 to 73 and averaged at age sixty-one.
