The guidelines for prostate cancer are, paradoxically, in a stable
state of flux. Unfortunately, there is little evidence supporting the
idea that early detection and intervention significantly alters the
mortality associated with prostate cancer. Because prostate cancer is
so slow growing, it takes decades of research to complete research trials
and distill the results into useful clinical recommendations. Notwithstanding
these limitations, here are the current guidelines from the United States
Preventive Services Task Force: http://www.ahrq.gov/clinic/uspstf/uspsprca.htm
From the American Cancer Society, these guidelines: http://www.cancer.org/docroot/CRI/content/CRI_2_2_3X_How_is_prostate_cancer_found_36.asp?sitearea=
And from the American Urological Association: http://www.urologyhealth.org/adult/index.cfm?cat=09&topic=250
You will see that there is no agreement on prostate cancer screening,
which is direct evidence that we just don't know what is the best way.
You will personally get to weigh in heavily on this decision and let
me know of your preference.
