Neurofibromatosis type 1 affects approximately one in every 2,500–3,000 people worldwide. Other possible signs include light-brown skin patches, freckles in unusual areas, and certain bone or eye abnormalities. There is currently no cure for NF1, but medical monitoring and treatments can help manage symptoms and complications. Doctors may recommend surgery for growths that cause significant problems, while certain medications are available for specific types of tumors. Anyone experiencing unexplained skin lumps should consult a healthcare professional, as many different conditions can cause similar symptoms.
