Researchers are looking for new, non-invasive ways to diagnose and monitor brain tumors by studying blood samples, eye fluid, and urine. The study will analyze special cells and molecules in these samples to see if they can help doctors detect tumors earlier and track how well treatment is working. This could eventually reduce the need for more invasive testing.
Current methods to diagnose and monitor brain tumors often require invasive procedures like biopsies or frequent imaging. This study aims to find markers in easily collected samples—like blood and urine—that could help doctors track the disease and spot treatment resistance or tumor progression much more simply.

If you join, you'll provide blood samples, urine samples, and possibly eye fluid samples before your surgery and again 3 months after your surgery. The researchers will analyze these samples to look for tumor markers and compare results between brain tumor patients, people with less serious brain tumors, and people without brain tumors. The study involves two main visit timepoints spread over a 3-month period.
