What is neurofibromatosis?
The tumors that neurofibromatosis causes are typically noncancerous but can become cancerous in some cases, explains Mayo Clinic. Symptoms of neurofibromatosis 1 include flat, brown spots on the skin, soft bumps on or under the skin, freckling in the groin or armpits area, learning disabilities and a larger than average head size. Symptoms of neurofibromatosis 2 include poor balance, gradual hearing loss and ringing in the ears. Symptoms of schwannomatosis include painful tumors on the cranial, peripheral and spinal nerves and chronic pain. Complications of neurofibromatosis include visual difficulties, neurological issues, cardiovascular problems, skeletal issues and anxiety concerning appearance.
