Spinal cancer often spreads through the subarachnoid CSF (cerebrospinal fluid), or through the blood. Metastases via the lymphatics are rare. Spinal tumor growth may affect the spinal vertebrae, blood vessels, nerve roots, meninges and cells of the spinal cord itself.The compression of the spinal cord produces vast symptoms and may be permanently damaged.pinal malignancies are most often secondary tumors resulting from metastasis.
