Brain metastases are the most common intracranial tumors in adults, accounting for significantly more than 50% of brain tumors. About 30~40% of all cancer patients is known to develop brain metastases. There has been an increase in metastatic brain lesions due to better early detection, as well as better treatments for primary cancer leading to longer patient survival.
Primary brain tumors are tumors that originate from the tissues of the brain or the brain's immediate surroundings. Glioblastoma (GBM) is the most common and aggressive malignant primary brain tumor in adults. Glioblastoma accounts for over 60% of all primary brain and CNS tumors. Only 10% of patients survive 5 years following diagnosis.
