How do doctors grade a brain tumor?

ANSWER

Tumor grades help your doctor plan your treatment and give you an idea of how fast the tumor may grow.

  • Grade 1. The cells look nearly normal and grow slowly. Long-term survival is likely.
  • Grade 2. The cells look slightly abnormal and grow slowly. The tumor may spread to nearby tissue and can come back later.
  • Grade 3. The cells look abnormal and are actively growing into nearby brain tissue. These tumors tend to come back.
  • Grade 4. The cells look most abnormal and grow and spread quickly.
