ABCD rating

Overview
ABCD rating, also called the Jewett staging system or the Whitmore-Jewett staging system, is a staging system for prostate cancer that uses the letters A, B, C, and D.


 * “A” and “B” refer to cancer that is confined to the prostate.
 * “C” refers to cancer that has grown out of the prostate but has not spread to lymph nodes or other places in the body.
 * “D” refers to cancer that has spread to lymph nodes or to other places in the body.

ABCD rating can also refer to a test for the warning signs of melanoma, usually found in moles.


 * "A" Asymmetry
 * "B" Border Irregularity
 * "C" Color. If the patch is multi-colored, it may be melanoma.
 * "D" Diameter. If the patch is wider than 6 millimeters, it may be melanoma.
