Stages of Prostate Cancer. With regard to prostate cancer, staging measures the extent of the disease, and is based on the size of the tumor, whether the cancer has spread outside the prostate, and, if so, where it has spread. There are five stages: stages 1 through 4 and recurrent cancer. Tests used to determine stage include the digital rectal exam, PSA test, transrectal ultrasound, and biopsy. Stages of Prostate Cancer: An Overview
At 81, a prostate cancer diagnosis is not entirely surprising. According to the Cleveland Clinic, 80 percent of men who reach their 80s will have some cancerous cells in the prostate. The severity of prostate cancer is measured in stages. Stage 1 is the least advanced, and only found within the prostate, according to The National Cancer Institute. It is detected by biopsy, testing for a man's Gleason score and PSA (prostate-specific antigen) level. The higher the PSA level in the blood, the more likely there is cancer.
