What are the Key Histological Features Indicating Aggressiveness?
Several histological features can indicate the aggressiveness of a tumor: - Mitotic Rate: A high mitotic rate suggests rapid cell division. - Nuclear Pleomorphism: Variability in the size and shape of nuclei often correlates with malignancy. - Necrosis: Areas of dead tissue within a tumor can indicate a high-grade tumor. - Invasion: Tumors that invade surrounding tissues or vessels are considered more aggressive. - Angiogenesis: The formation of new blood vessels within the tumor is a sign of high aggressiveness.
