Several grading systems are used depending on the type of cancer:
Gleason Score: Used for prostate cancer, this scoring system ranges from 2 to 10, with higher scores indicating more aggressive cancer. Nottingham Grading System: Employed for breast cancer, it evaluates tubule formation, nuclear pleomorphism, and mitotic count, with scores ranging from 1 to 3. Fuhrman Grade: Commonly used for renal cell carcinoma, it evaluates nuclear characteristics and ranges from 1 to 4.
