Cancer spreads to the nervous system by direct invasion, compression, or metastasis. Direct invasion or compression from continuous tissues relates to the proximity of the nervous system to other structures, such as the brachial plexus, lumbosacral plexus, vertebral neuroforamina, base of skull, cranium, and pelvic bones.
