Brain Tumor Grades: Biopsy and Prognosis
A pathologist will examine a patient’s biopsy sample to determine the exact type of tumor, whether the tumor is benign or malignant and how serious it is (its grade).
Brain tumor grading system:
|(World Health Organization grading system)|
|Grade I tumor|
|Grade II tumor|
|Grade III tumor|
|Grade IV tumor|
A changing diagnosis
The grade of a brain tumor might change. Reasons for this include:
- Brain tumors sometimes change (usually to a higher grade)
- The biopsy sample might not represent the entire tumor
A change from a low-grade tumor to a high-grade tumor happens more often in adults than in children.
Making the diagnosis without a biopsy
If doctors cannot perform a biopsy, they will determine a treatment plan on test results.
