What percentage of spine tumors are 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%.

Are most spinal tumors benign?

Primary spinal tumors are those that originate in the spine. They are relatively rare, typically benign (noncancerous) and represent a small percentage of spinal tumors. Malignant tumors may also originate in the spine, although more often they spread to the spine from elsewhere in the body.

How often are spinal tumors cancerous?

Spinal cancer affects about one in 140 men and one in 180 women, making it a relatively rare disease. Certain hereditary disorders raise the risk of spinal cancer, as do a compromised immune system and exposures to radiation therapy and certain industrial chemicals.

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.

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.

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).

Do benign tumors need to be removed?

In many cases, benign tumors need no treatment. Doctors may simply use “watchful waiting” to make sure they cause no problems. But treatment may be needed if symptoms are a problem. Surgery is a common type of treatment for benign tumors.
