In order to diagnose throat cancer, it is necessary to combine the clinical symptoms of patients with electron laryngoscopy, enhanced CT examination of the neck and pathological biopsy and other examinations to make a clear diagnosis.
1. Clinical symptoms: The main clinical symptoms of pharyngeal cancer include: throat pain, foreign body sensation, hoarseness, cough with blood, difficulty in swallowing, and even dyspnea in serious cases. Pharyngeal cancer is most common in middle-aged and old-aged men, who have long-term smoking, drinking and other bad habits.
2. Electron laryngoscopy and neck enhancement CT examination: For middle-aged and old-aged patients with the above symptoms, it is routinely recommended to improve electron laryngoscopy examination, and NBI examination can be carried out if there are conditions. It can visualize the extent of lesions and inflammation in the pharynx. With the enhanced CT examination of the neck, we can understand the scope of the lesion and whether there is any lymph node metastasis in the neck.
3. Pathological biopsy: For patients who are highly suspected of malignant tumor, it is recommended to perform pathological biopsy in time to clarify the nature.
Therefore, if throat cancer is suspected, it is necessary to go to the hospital in time to improve the relevant examination and standardize the treatment.
