Did you know there are over 100 different types of primary brain tumors? About 74% of them are not cancer. The tumors that are cancerous are usually glioblastomas (52% of all malignant brain tumors). 🧠
Primary brain tumors aren't staged like other cancers. Instead, a grading system is used depending on how aggressive the tumor is.
Treating brain tumors is complex and not curative, so many patients take part in clinical trials.
