How is astrocytoma graded?

ANSWER

Like other tumors, astrocytomas are graded on a scale of I to IV, based on how abnormal the cells look and how fast they grow. Grade IV tumors are the most aggressive in their growth. Most astrocytomas in adults are high grade. This means the cells look abnormal and grow quickly.
