Many patients do not have any signs and symptoms until NPC reaches an advanced stage. Many patients are unable to recognize their sickness and receive treatment at the optimal time. Statistics figures show that approximately 80% of unscreened patients are diagnosed with advanced NPC1. Up to now, there is no vaccination for the prevention of NPC as a type of virus-associated cancer. Early screening is one of the best ways to prevent NPC. It could greatly increase the chance of successful treatment as well.
