Multiple Myeloma – This is the primary malignancy of the spine and other bones.Chordoma – This is the most common primary malignant spinal tumor in adults and accounts for almost all of the metastases in other areas because of being lymphoproliferative.Osteosarcoma – This is the rarest form of spinal tumor and usually occurs on the lumbosacral area.Ewing Sarcoma – This is the most common spinal tumor in children.The most common site of development is the thoracic spine. Chondrosarcoma – This is the second most common spinal tumor accounting for up to 12% of all spinal tumor cases.This causes swelling on the spinal cord leading to loss of spinal cord function below the level of the spinal tumor. Intramedullary – This tumor develops inside the spinal cord and usually present as gliomas or astrocytomas.This type of tumor is accompanied by nerve root involvement and spinal cord compression. Intradural – The tumors grow in the dura mater and come in the form of nerve sheath tumors such as meningiomas or neurofibromas.This type comprises most of the spinal tumors and is responsible for most of the metastasis outside the central nervous system. Extradural Spinal Tumors – These tumors grow outside the dura mater in between the meninges and the vertebral column.Spinal cancer may be categorized according to the type of cellular changes or the location of the tumor. The compression of the spinal cord produces vast symptoms and may be permanently damaged. Spinal tumor growth may affect the spinal vertebrae, blood vessels, nerve roots, meninges and cells of the spinal cord itself. Spinal cancer often spreads through the subarachnoid CSF (cerebrospinal fluid), or through the blood. The incidence of spinal cancer increases with age and can occur in both males and females. Spinal cancer can occur in the form of lymphoma and accounts for 1% of the central nervous system lymphomas. Spinal malignancies are most often secondary tumors resulting from metastasis. Primary spinal tumors are sometimes benign, but more commonly they are malignant. Spinal tumors may be primary which start in the spinal cord or secondary which result from metastasis (transmission of cancerous cells) from other cancers in the body. Spinal cancer, or more commonly known as spinal tumor, is a neoplasm (an abnormal growth) in the spinal cord.
