Artificial Intelligence: Deep Learning for Grading Prostate Cancer

Basics: What is a Gleason Score? One important component of staging your cancer is the grade of the cancer. While the stage of your cancer looks at where the cancer is present in your body -- how it is behaving at the macro level -- the grade describes what the actual cancer cells look like under a microscope -- how they are behaving on a micro level. Traditionally, prostate cancer grades were described according to the Gleason Score, a system named for the pathologist who developed it in the 1960s. Dr. Donald Gleason realized that cancerous cells fall into 5 distinct patterns as they change from normal cells to tumor cells.
