There
are several grading systems for Prostate Cancer, but the Gleason
system is the most common.
It
is based on a score of 2 (the lowest) to 10 (the highest).
Lower scores 2-4 mean that the cancer cells look similar to the
normal cells.
A
score of 5-6 is intermediate.
A
score of 7-10 means the cancer cells are more likely to be advanced.
