鼻咽癌（ＮＰＣ）的发病存在地区差异。我国南方，特别是广东省是ＮＰＣ的高发区，而北方属相对低发区。ＮＰＣ病灶隐匿，临床症状缺乏特异性，容易被忽视。低发区的医患人员往往对ＮＰＣ认识不足，加之缺乏特异性早期诊断方法，使得患者确诊时多为中晚期，失去了治愈的时机。 There are regional differences in the pathogenesis of nasopharyngeal carcinoma (NPC). The south of our country, especially Guangdong Province, is the high incidence area of ​​NPC, while the north belongs to the relatively low incidence area. NPC lesions hidden, the lack of specificity of clinical symptoms, easily overlooked. Low-incidence area of ​​medical staff often NPC lack of knowledge, coupled with the lack of specific early diagnosis, making the diagnosis of patients mostly in the late, lost the opportunity to cure.
