What are the risks associated with removing a spinal tumor?

Paralysis, etc.: This depends on where the tumor is and how complex it is. Some, like ependymomas are benign, but can be in the center of the spinal cord, making removal all but impossible. If the tumor is wrapped around the spinal cord, removal might be possible, but the cord can be damaged, and complications like paralysis can occur. If a nerve is compressed, pain can occur, or numbness.
