Over 90% of prostate cancer cases are prostatic adenocarcinoma,
meaning that the cancer occurs in the gland or ducts
that absorb or secret fluid. Prostatic sarcoma as a

cancer that has extended to thew bones. The tumor associated
with prostate cancer usually grows in the peripheral
zone and may extend to the prostatic capsule, the seminal
vesicles, the lymph nodes, and bones.
