What is the growth rate of a brain tumor?

The actual tumor doubling times of malignant gliomas ranged from 15.0 to 21.1 days, averaged 19.5 +/- 1.9 days, and showed no significant variation according to histopathologic differences. By determining the tumor doubling time in this manner, the growth rate of a tumor can be assessed.

Are brain tumors fast or slow-growing?

What is the survival rate for benign brain tumors?

MRI creates pictures of soft tissue parts of the body that are sometimes hard to see using other imaging tests. MRI is very good at finding and pinpointing some cancers. An MRI with contrast dye is the best way to see brain and spinal cord tumors. Using MRI, doctors can sometimes tell if a tumor is or isn’t cancer.
