Update on Prostate Cancer Screening Guidelines
Update on Prostate Cancer Screening Guidelines
According to the American Cancer Society (ACS), about 1 in 6 men will be diagnosed with prostate cancer during the course of a lifetime, and about 1 in 36 will die of the disease. Most prostate cancers grow slowly, but in some cases progression is quick. In several studies, autopsies of older men who died from other diseases revealed that many of the patients also had undiagnosed prostate cancer. According to these studies, as many as 7 to 9 out of 10 patients had prostate cancer by 80 years of age. Scientists believe that prostate cancer begins with prostatic intraepithelial neoplasia (PIN)—microscopic changes in the size and shape of prostate cells.
