An ependymoma is a tumor that forms in your brain or spinal cord. Providers grade them from 1 to 3 based on how quickly they spread. Grade 3 ependymomas are cancerous. You’ll probably need surgery to remove the tumor. You might need other treatments like radiation or chemotherapy, too.

Ependymomas are primary tumors. That means they form directly in your brain or spinal cord (they don’t spread there from somewhere else in your body).
They’re a type of glioma. Ependymomas are the sixth most common brain tumor in children. But they can affect adults, too.
Healthcare providers grade ependymomas on a 1 to 3 scale, based on how quickly they grow. Grade 1 tumors grow the slowest and grade 3 grow fastest.
Grade 1 and 2 ependymomas are noncancerous (benign). They usually grow slowly and don’t spread (metastasize) from where they form.
Grade 3 ependymomas are cancerous (malignant). They grow more aggressively (much faster) than lower-grade tumors.
In addition to grades, there are several types of ependymomas, including:

An ependymoma can cause a lot of symptoms depending on where it forms. Some of the most common symptoms include:
Babies and very young children can’t tell you they’re feeling pain or other symptoms. You might notice:
Experts aren’t sure what causes ependymomas. They may happen by mistake when ependymal cells in your brain divide and replicate. Some genetic variations may cause them.
Some studies have found that people who carry the genetic variations that cause neurofibromatosis type 2 may be more likely to develop ependymomas. But experts can’t say for sure that they’re linked. They’re still studying this possible connection.
A healthcare provider will diagnose an ependymoma with a physical exam, a neurological exam and some tests. Your provider will ask about your symptoms, and when you first noticed them.
Your provider may use some of the following tests to diagnose an ependymoma:
Your healthcare provider will treat an ependymoma with:
The five-year survival rate for ependymomas is nearly 85%. That means around 85% of people are still alive within five years of being diagnosed. But this number may not apply to you or your unique situation. Your providers will tell you what can expect.
There are lots of factors that can impact your survival rate, including:
There’s no cure for cancer, but it’s possible to remove or destroy a grade 3 ependymoma with treatment.
Remember, there’s always a chance an ependymoma regrows (recurs), even after you’ve been declared cancer-free. That’s much more likely with grade 3 tumors. Your providers and surgeon will tell you what to expect based on your age and overall health.

Your provider will tell you how often you’ll need follow-up visits to monitor any changes in your body. You’ll need regular imaging tests to keep an eye on the ependymoma during treatment.
You may want to ask your healthcare provider:
Ependymomas are tumors that grow in your brain or spinal cord. There are lots of grades and types, but the good news is they’re all treatable. Many people successfully have surgery to remove an ependymoma with no long-term effects.
Your provider will help you understand everything you need to know about the ependymoma and which treatments you’ll need. Don’t hesitate to ask them any questions you think of. There’s no such thing as a silly question when it comes to your health or body.
