What Is It?
Neurofibromatosis (NF) is nervous system disease that causes skin defects and tumors on nerve tissues. It can also lead to other problems. The condition usually worsens over time. Although there is no known cure, treatment can help control symptoms.
The nerve tissue tumors begin in cells that protect nerves. These tumors can vary in size and occur anywhere in the body, including the skin, inner ear, brain, and spinal cord. Most are not cancerous, although some may turn cancerous over time.
