Your question: Can a spinal tumor be benign?

What percentage of spinal tumors are cancerous?

Overall, the chance that a person will develop a malignant tumor of the brain or spinal cord in his or her lifetime is less than 1%.

Can spinal cord tumors be benign?

Tumors that begin in and around the spinal cord are called primary spinal cord tumors. These tumors are rare. When they do occur, they are often benign, or noncancerous. Sometimes, however, they may be malignant, or cancerous, meaning they can spread to other parts of the body.

What causes benign tumors on spine?

These typically benign tumors arise from cells known as Schwann cells, hence the name. These nerve sheath tumors can be idiopathic (having no known cause), or they may develop due to a hereditary issue know as Neurofibromatosis type 2 (NF2).

Should I worry about a benign tumor?

Even though most benign tumors are harmless and can be left alone, it’s important they be monitored. And any tumor that is painful or growing requires a visit to the doctor.

How fast do spinal tumors grow?

Tumors that have spread to the spine from another site often progress quickly. Primary tumors often progress slowly over weeks to years. Tumors in the spinal cord usually cause symptoms, sometimes over large portions of the body. Tumors outside the spinal cord may grow for a long time before causing nerve damage.

Survival rates for more common adult brain and spinal cord tumors

Type of Tumor 5-Year Relative Survival Rate
Oligodendroglioma 90% 82%
Anaplastic oligodendroglioma 76% 67%
Ependymoma/anaplastic ependymoma 92% 90%
Meningioma 84% 79%

Where are most spinal tumors located?

The most common of these types of tumors develop in the spinal cord’s arachnoid membrane (meningiomas), in the nerve roots that extend out from the spinal cord (schwannomas and neurofibromas), or at the spinal cord base (filum terminale ependymomas).

How often are spinal tumors malignant?

Primary and Metastatic Spinal Tumors

Metastatic spinal tumors are those that have spread to the spine from other areas of the body. If a tumor is able to spread, this usually means it is malignant. Between 30 and 70 percent of cancer patients develop metastatic spine cancer during the course of their disease.

How rare are spinal cord tumors?

Primary spinal cord tumors — tumors that originate in the spine rather than spread to the spine from elsewhere in the body — are usually benign. They are so rare that they account for only a half of one percent of all newly diagnosed tumors. Malignant primary tumors of the spinal cord are even less common.
