Prostate cancer staging and biopsy Prostate cancer staging is very important in its treatment; it is designed to tally with the Prostate Gleason Score. The biopsy of prostate cancer involves the removal of small hollow needle-core samples from the prostate gland and examining for the presence of cancer under a microscope. Pathologists are specially trained to carry out prostate cancer biopsy to stage the disease. To determine the extent of the disease, usually, it is being graded by pathologists on the scale of 1 to 5. The scaling represents the physical appearance of the cancerous tissues when viewed with a microscope. Typically, it determines how much of the cancerous tissue looks like a normal prostate tissue with scale one indicating that the tissue looks very much like normal tissue while scale 5 represents that the tissue looks very abnormal. This scaling is used to denote the growth patterns of cancer. Scale number 2, 3 and 4 stands in between the two extremes of 1 and 5, denoting a gradual increase in abnormality of the tissue.
