Rationale:
*Patients won't be told they have a 6 out of 10 cancer, and then think it is an intermediate grade cancer that is worrisome. Instead, they will be told they have a 1 out of 5 cancer.<ref name=jhu2014>URL: [http://urology.jhu.edu/newsletter/2014/prostate_cancer_2014_19.php http://urology.jhu.edu/newsletter/2014/prostate_cancer_2014_19.php].
