In head and neck tumors, there is no definition of early cancer. If T1N0M0, no lymph node and distant metastasis, will be early cancer, it is difficult to detect the tumor at early phase in head and neck tumor except for tongue and laryngeal cancer. Because it is hard to define it at early stage in the tumor surrounding by bony structure or tumor growing endophytically. Although almost tumor of head and neck were easily diagnosed by inspection and palpation, total imaging examination should be done actively for detection of early stage of cancer.
在头颈部肿瘤中，尚无早期癌症的定义。如果T1N0M0（无淋巴结及远处转移）就属于早期癌症，那么除舌癌和喉癌外，头颈部肿瘤很难在早期检测到肿瘤。因为在被骨质结构包围或向内生长的肿瘤中，很难在早期对其进行定义。尽管几乎所有头颈部肿瘤通过视诊和触诊很容易诊断，但仍应积极进行全面的影像学检查以检测癌症的早期阶段。
