Diagnosis typically involves imaging studies, such as MRI (Magnetic Resonance Imaging) and CT (Computed Tomography) scans, which help visualize the brain's structure and identify the presence of tumors. In some cases, a biopsy may be performed to confirm the diagnosis and determine the type of cancer cells present. Additional tests, such as a lumbar puncture or PET (Positron Emission Tomography) scan, may be used to assess the extent of the disease.
