Spinal Cord Tumor Overview
A tumor forms when an abnormal cell proliferates to form a mass of abnormal cells. Spinal cord tumors are tumors that form on the spinal cord or in the area around it.
A spinal cord tumor may be cancerous (malignant) or noncancerous (benign). Even if benign, a tumor often causes pain and discomfort because it pushes on the spinal cord or nerves.
A spinal cord tumor may be called “primary,” which means the cancer started in the spinal cord, or “secondary,” which means the cancer started somewhere else in body and spread to the spinal cord. Most of the time, spinal cord tumors are secondary tumors. A spinal cord tumor is often a cancer of the breast, thyroid, lung, prostate, or another cancer that has extended throughout the body to reach the spine.
Spinal cord tumors are sometimes caused by a genetic disorder, like neurofibromatosis. Some people get spinal cord tumors because they were exposed to toxic chemicals that can cause cancer or have been exposed to radiation.
Facts about spinal cord tumors
Spinal cord tumors are relatively uncommon. It's much more common to develop a brain tumor than a tumor on the spinal cord. A spinal cord tumor may form inside the spinal cord itself or around the bones that make up the spine. Spinal cord tumors cause problems with the nerves, blood vessels, and bones, and can prevent sufficient blood flow throughout the body as it grows.
Some spinal cord tumors can be successfully treated. The earlier you tell your doctor about your symptoms, get a diagnosis, and start treatment, the better your outcome. But spinal cord tumors often cause permanent damage to the nerves and result in disability.
Types of spinal cord tumors
Spinal cord tumors come in many different types, including:
Leukemia or lymphoma, cancers of the blood
Myeloma, cancer of the bone marrow
Medulloblastomas, which start in the brain and metastasize to the spine, and are most common in children
Gliomas or gangliogliomas, cancers that form in cells called glial cells (glial cells also include neurons)
Chordomas, which form in the spine and can push against it
Schwannomas, which start inside the peripheral nerves
Meningiomas, which start in the tissues around the spinal cord (meninges)
Spinal cord tumors can cause many different symptoms:
Inability to control the bowels and/or bladder
Weak muscles that you can't seem to control, so that you fall or have trouble walking
An unusual feeling or sensation in the legs
Feeling cold in the hands, fingers, or legs
Spinal cord tumors often cause back pain, including:
Feeling worse when you strain in any way, sneeze, or cough
Increased pain when you lie down
Pain that’s specific to the spine
Extreme pain that isn't improved by taking medication
Pain that feels worse as time passes
Pain that spreads into the arms, feet, legs, or hips
A doctor will usually perform a neurologic exam to diagnose a spinal cord tumor. The exam will look for these signs:
Soreness in the area of the spine
Inability to feel pain, heat, or cold
An abnormal reflex response
These tests help your doctor see a spinal cord tumor and find out more information about it:
Imaging tests of the spine, such as a CT scan, MRI, or myelogram, which uses an X-ray in combination with an injection of contrast dye into the spine to better see the tumor
Examination of the cerebrospinal fluid and the cells in the fluid
Treatment for a spinal cord tumor is different for everyone and depends on the type of tumor, its location, and your overall health. These are treatment options:
Surgery to remove all or part of the tumor
Radiation therapy, which is sometimes used in addition to surgery
Corticosteroid medications to lessen swelling
Since it's not understood why most primary spinal cord tumors develop, experts don't know how to prevent them.
Managing spinal cord tumors
Working with your doctor can help you to ease your symptoms so that you feel more comfortable before and during treatment.
After your treatment, you may need physical therapy to strengthen muscles and help them work properly again.
During the course of your treatment, always notify your doctor or seek emergency medical assistance if your symptoms suddenly become more severe or change in some way.

Key points to remember
If you are currently undergoing treatment for any type of cancer and develop back pain, you should let your doctor know right away. It's also a good idea to contact your doctor about any back pain that worsens or doesn't go away with time.
