Welcome, @pma2022. You're wise to do your research to have an informed discussion with your care team. While we wait for @lioness31277, I'm also tagging @jcorcoran @annrmarie and @beckyziegler on this discussion to bring in more experiences and voices to help address your questions.

In the meantime, here's some info from Mayo Clinic:
- Ependymoma https://www.mayoclinic.org/diseases-conditions/ependymoma/cdc-20350144

This page from the National Cancer Institute (US) also includes active clinical trials
Ependymoma Diagnosis and Treatment https://www.cancer.gov/rare-brain-spine-tumor/tumors/ependymoma

When do you meet with your doctors again to discuss your options, PMA?
