Currently, there are several drug treatments available for type 2 neurofibromatosis! The main one available in China is bevacizumab, which belongs to vascular endothelial growth factor receptor inhibitor and is a biological agent. It can effectively control the growth of tumor blood vessels, thus causing poor supply of nutrients to the tumor and leading to necrosis. According to the latest research, the efficiency is above 50%. However, such drugs are expensive, and if needed, patients are advised to apply for government poverty assistance or seek help from the Red Cross!
