Gastroscopy is difficult to observe laryngeal cancer lesions, and laryngeal cancer is mainly examined by laryngoscopy.
Gastroscopy enters into esophagus and stomach from oral cavity and pharynx, and stays very briefly when passing through the throat because patients may have nausea and vomiting when entering into the throat during endoscopy, so the stay time is very short, and it is very difficult to observe the shape of the tumor and the diseased part in detail when the disease occurs in this part.
Laryngoscopy is more accurate for laryngeal cancer examination. Laryngoscopy can enter through the nasal cavity, so that it can clearly observe the situation of nasal cavity, pharynx and larynx, take photos of suspicious parts, remove tissues of lesions, and carry out pathological biopsy to confirm the diagnosis of the disease.
When laryngeal cancer is suspected, it is necessary to actively consult a doctor, choose reasonable examination under the guidance of a physician to make a clear diagnosis, and actively carry out treatment.
