Can nerve tumors be removed?

What are nerve tumors called?

Schwannomas and neurofibrosarcomas are nerve sheath tumors, which means they involve the coating around nerve fibers that transmit messages to and from the brain and spinal cord (nervous system) and the rest of the body. Schwannomas are most often nonmalignant tumors. Neurofibrosarcomas are malignant tumors.

Can tumors grow on nerves?

Nerve tumors develop in the nerve sheath (protective covering) and support tissue. Most are benign. Even some noncancerous tumors need treatment, though, because they can press on nerves and cause pain, nerve damage and/or loss of function. Nerve tumors can grow slowly or quickly, depending on the type.
