Tumors of the Anterior Prostate: Implications for Diagnosis and Treatment.

Tumors of the anterior prostate (ie, the portion of the prostate anterior to the urethra) account for approximately 20% of all prostate cancers. Although anterior prostate cancers frequently occur, they have historically been underdetected because of infrequent sampling. Recent advances in multiparametric magnetic resonance imaging and improved biopsy schemes have significantly increased our diagnostic accuracy for detecting anterior tumors.
