First of all, there are there are three different types of Neurofibromatosis, NF1, NF2 and
Schwannomatosis. Each condition has its own set of symptoms. Many of the symptoms are related to the nervous system. People with NF are at a somewhat increased risk for cancer. Many people with NF1 have 100's if not 1,000's of visible tumors all over their body. The severity of NF can vary widely from person to person. Unfortunately, not much can be done to prevent symptoms of NF. It is very important to have knowledgable doctors that can followed patients with NF closely in order to find problems that can be treated before they get worse.
