What are the laryngeal diseases with similar symptoms to laryngeal cancer

The main symptoms of laryngeal cancer are hoarseness, dyspnea, cough, dysphagia, cervical lymph node metastasis, etc. High-risk groups should pay attention to quitting smoking, drinking moderately, and taking preventive measures. It is often similar to the following laryngeal diseases:

1. Nodular laryngitis. It manifests as intermittent hoarseness, which is aggravated at night and lighter in the morning. There is a dry feeling and slight pain in the throat and increased laryngeal secretions. It is prone to occur at the junction of the front and middle 1/3 of the vocal cords. There are symmetrical mucosal nodules on the free edge, which are edematous, smooth in surface, as big as rice grains, and with a wide base. Congestion is effective in reducing voice during rest, nebulization inhalation, ultrashort wave physical therapy, and appropriate antibiotic treatment.

2. Laryngeal tuberculosis. Patients with laryngeal tuberculosis have varying degrees of sore throat, and most of them have tuberculosis lesions in the lungs. The lesions are granular, pink or pale edematous, often accompanied by shallow ulcers covered with purulent secretions. The posterior union is a common site for laryngeal tuberculosis, while laryngeal cancer is rare. Anti-tuberculosis treatment is effective, and biopsy cytology and secretion smears to find acid-fast bacilli are helpful for diagnosis.

3. Laryngeal keratosis. It is manifested by hoarseness and discomfort in the throat. It is more common in middle-aged men. Laryngoscopy shows thickened vocal cords, which appear as pink or white patches. The surrounding tissues often have inflammatory reactions. It is mostly unilateral, but can also affect both sides of the vocal cords. It is easy to relapse and has a tendency to become malignant. It can be confirmed by pathological biopsy.
