The survival rate for all cancers combined and for certain site-specific cancers have improved significantly since the 1970s, due, in part, to both earlier detection and advances in treatment. Survival rates markedly increased for cancers of the prostate, ovary, breast, colon & rectum, and for leukemia. With new treatment techniques and increased utilization of screening, there is hope for even greater improvements in the not-too-distant future.

PSA Screening Program and Its Effect on Tyrol’s Prostate Cancer Mortality Rate Horninger W, MD et al Am J Urol Review 2005 Apr 3:4, 172-175 1993 Mass screening project launched in Tyrol, Austria, offers PSA testing free to all men ages 45-75; 65,123 enrolled Treatment for Tyrol subjects with: Elevated PSA levels advised to undergo DRE and biopsies Organ-confined lesions RRP or EBR T3 lesions EBR only Metastases ADT No organized screening in the rest of Austria. Treatments varied. WJC
