What is the difference between a benign brain tumor and a malignant (cancerous) brain tumor?
Benign brain tumors are slow-growing tumors that can be removed or destroyed if in an accessible location. Malignant tumors (brain cancer) are rapidly growing tumors that invade or infiltrate and destroy normal brain tissue. No one is certain why, but some benign brain tumors may change over time to become malignant. Tumors are graded to indicate how quickly they are growing. Most medical institutions use the World Health Organization (WHO) classification system to identify brain tumors. The WHO classifies brain tumors by cell origin and how the cells behave, from the least aggressive (benign) to the most aggressive (malignant).Some tumor types are assigned a grade, which signifies the rate of growth. There are variations in grading systems, depending on the tumor type. The classification and grade of an individual tumor help predict its likely behavior. The distinction between benign and malignant can be ambiguous. Some benign tumors can be as dangerous as malignant ones if in a dange
