They typically report stopping and starting all over again, making an effort to urinate the complete volume of the bladder. A digital rectal exam (DRE) is a simple procedure in which a doctor inserts a lubricated, gloved finger into the anus to check for abnormalities in the rectum and pelvic area. Traditionally, prostate cancer grades were described according to the Gleason Score, a system named for the pathologist who developed it in the 1960s. PSAFT : Prostate-specific antigen (PSA) is a glycoprotein that is produced by the prostate gland, the lining of the urethra, and the bulbourethral gland.
Increases in glandular size and tissue damage caused by benign prostatic hypertrophy, prostatitis, or prostate cancer may increase circulating PSA levels. Prostate specific antigen (PSA) is a protein produced primarily by cells in the prostate, a small gland in males that encircles the urethra and produces a fluid that makes up part of semen. Most of the PSA that the prostate produces is released into this fluid, but small amounts of it are also released into the blood. Donald Gleason realized that cancerous cells fall into 5 distinct patterns as they change from normal cells to tumor cells.
