[1] [2] When abnormal prostate tissue or cancer is found early, it may be easier to treat and cure, but it is unclear if early detection reduces mortality rates. [2] Screening precedes a diagnosis and subsequent treatment.

In a 2015 articles in the Journal of Urology, Thompson reported multi-parametric MRI detection of significant prostate cancer had sensitivity of 96%, specificity of 36%, negative predictive value and positive predictive values of 92% and 52%; when PI-RADS was incorporated into a multivariate analysis (PSA, digital rectal exam, prostate volume ...
Prostate cancer was estimated to be the second leading cause of death by cancer in the US in 2018. [35] There are different methods used in screening for prostate cancer prostate biopsy, prostate-specific antigen testing (PSA), and digital rectal examination (DRE).

However, defining disease progression is problematic. Progression in active surveillance programs has been defined based on PSA kinetics or exceeding a given PSA threshold, increased extent of cancer or higher grade disease on prostate biopsy, change in digital rectal examination, and proceeding to curative intervention.
The majority of treatable/treated cancers are of Gleason scores 5-7 and are detected due to biopsy after abnormal digital rectal exam or prostate specific antigen evaluation. The cancer is typically located in the peripheral zone usually the posterior portion, explaining the rationale of performing the digital rectal exam. [citation needed]
