EBV - Nose & Throat Cancer Marker

EBV (Epstein-Barr virus) is a kind of herpes virus, found everywhere spreading between humans through saliva and it is common in people diagnosed with nasopharyngeal cancer (NPC). It grows in a ‘hidden’ area at the back of the nose called the nasopharynx, it is not easy to detect. Nasopharyngeal cancer begins when cells in this area start to grow out of control. Exposure to EBV can increase the risk of developing NPC.
