Not detected: GERD requires lower endoscopy and on rare occasion reaches vocal cord area causing laryngopharyngitis , that part of the pharynx behind the voice box. Throat cancer involves nasopharynx. oropharynx and to some degree hypopharynx, all areas essentially missed on lower endoscopy. An oral, digital exam can detect pharyngeal Ca mostly by palpation and then bx. If lump in neck have it checked.
