When breast cancer spreads to the spine, it's known as bone metastasis. And unfortunately yes, breast cancer that has spread to the bones may spread to other areas such as the brain as well. This happens when cancer cells break away from the primary tumor and travel through the circulatory system. The most common areas for breast cancer to spread are the bones, lung, liver, and brain.
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.
