Let me tell you about the key points of diagnosis of laryngeal cancer

Laryngeal cancer is not unfamiliar to everyone. Many patients will have some obvious symptoms in the early stage, but they do not pay attention to it. So what are the diagnostic measures for laryngeal cancer ? The following is a detailed answer from relevant experts.

1. Supraglottic type: The incidence rate is about 30%. In the early stage, there is a foreign body sensation in the throat and discomfort in the pharynx. If the vocal cords are invaded, there will be hoarseness and difficulty breathing. In the late stage, there will be bloody sputum. This tumor develops quickly and is easy to metastasize to the deep upper group of cervical lymph nodes. This is the key point for the diagnosis of laryngeal cancer.

2. Glottic type: about 60%, progressive hoarseness, glottis obstruction, laryngeal wheezing and dyspnea, bloody sputum in late stage. It is not easy to metastasize to cervical lymph nodes, which is also the key point of laryngeal cancer diagnosis.

3. Subglottic type: accounting for about 6%, there may be no symptoms in the early stage, but cough, bloody sputum, obstruction of the subglottic area and difficulty breathing may occur later

4. The key point of diagnosis of laryngeal cancer is that the tumor is cauliflower-like, ulcer-like, nodular or mass-like under laryngoscope. The vocal cords can move in the early stage, but they are restricted or fixed later.
