A spinal tumor is an abnormal tissue growth associated with cancer. Tumors in the spine may cause back pain from expansion of the bone or from weakening the bone. Back pain along with symptoms of neurological problems such as weakness or numbness in the limbs and loss of appetite, nausea and unplanned weight loss may be indicative of a spinal tumor. Tumors rarely originate in the spine (primary tumors) rather the majority of spinal tumors have metastasized from another area in the body. For patients with cancer, any new complaint of spine pain or neurological deficits may indicate that the cancer has spread to the spine. Treatment for spinal tumor varies depending on the location of the spinal tumor.
