Classification of Metastatic Brain Tumors
Many tumor or cancer types can spread to the brain, the most common are lung cancer, breast cancer, melanoma, kidney cancer, bladder cancer, certain sarcomas, testicular tumors and germ cell and many others. Some cancers only spread to the brain infrequently, such as colon cancer, and others such as prostate cancer almost never spread. Brain tumors can directly destroy brain cells may indirectly damage or inflammation, compressing other parts of the brain as the tumor grows, inducing brain swelling and causing increased intracranial pressure.
The classification of metastatic brain tumors depends on the exact location of the tumor within the brain, the type of tissue involved, original location of the tumor and other factors. Very rarely, a tumor can spread to the brain, although the original site or location of the tumor is unknown, to which is called cancer of unknown primary origin.
Metastatic brain tumors occur in about one quarter of all cancers that metastasize (spread through the body). These tumors are more common than primary brain tumors occur in approximately 10 to 30% of cancers in adults.
