A spinal tumour is an abnormal mass of tissue within or surrounding the spinal cord and spinal column, in which cells grow and multiply uncontrollably, seemingly unchecked by the mechanisms that control normal cells. Spinal tumors can be benign (non-cancerous) or malignant (cancerous). Primary tumors originate in the spine or spinal cord and metastatic or secondary tumors result from cancer spreading from another site to the spine.

Indications for surgery vary depending on the type of tumor. Primary spinal tumors may be removed through complete en bloc resection for a possible cure. In patients with metastatic tumors, treatment is primarily palliative, with the goal of restoring orpreserving neurological function, stabilizing the spine, and alleviating pain. Indications for surgery include intractable pain, spinal cord compression, and the need for stabilization of impending pathological fractures.
