Gleason scores and prostate cancer grading system. The Gleason score for cancer grading is computed by adding the primary and secondary scores from a whole slide H&E-stained microscopic biopsy image. The cancer detection process in histopathology consists of categorising stained microscopic biopsy images into benign and malignant. The Gleason score predicts the aggressiveness of prostate cancer. The images used for Grade 1–5 were scanned at 40× optical magnification, respectively.
