Summary

This study is creating a large database of brain tumor patients (70,000 people) to help doctors better understand, diagnose, and treat these cancers. It collects medical images, lab results, and patient outcomes over time. The goal is to improve prediction of tumor behavior and guide future research, not to test a new treatment directly.
