Meningioma growth signs differ by where the tumor sits

- Tested in people
This was tested in people. That is the most reliable kind of research we share.
Doctors looked back at tumor samples from people. It is not a treatment.
The short version
Where a meningioma grows is linked to how fast it grows.
What was studied. Doctors looked back at 298 meningiomas taken out by surgery. The tumors were diagnosed between 2013 and 2025. Doctors checked each tumor's grade and its signs of cell growth.
What they found. Of the tumors, 55.0% were Grade 1, 41.6% were Grade 2, and 3.4% were Grade 3. Higher grade tumors showed more signs of fast cell growth. Tumors on the outer surface of the brain were more often higher grade. Tumors at the skull base or in the spine were mostly lower grade.
What this means, and what it doesn't
What it could mean: Tumor grade and growth signs help doctors judge how a tumor may act. This work suggests the tumor's location fits into that picture too. That may help your care team plan follow-up care with you.
What it doesn't mean: This is not a new treatment, and it is not a promise of a cure. Doctors only looked back at tumor tissue that was already removed. Location alone does not tell you what your own tumor will do. Nothing here changes the care you can get today.
