However, just because breast cancer has spread to the spine doesn't mean that it will spread to other areas. Doctors can treat the new tumors with radiation and new medications called bisphosphonates can block the progression of tumor cells in the bone and prevent the cancer from spreading to other organs.
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. Spinal cancer can occur in the form of lymphoma and accounts for 1% of the central nervous system lymphomas. The incidence of spinal cancer increases with age and can occur in both males and females.
