The main diagnostic points of laryngeal cancer are detailed for everyone

Laryngeal cancer is a common disease that everyone should be familiar with. How much do you know about the diagnosis points of laryngeal cancer? Below, experts will introduce the diagnosis points of laryngeal cancer.

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: accounts 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.

5. The key points for diagnosing laryngeal cancer include hoarseness for more than 4 weeks, age over 40 years old, or patients with throat discomfort, foreign body sensation, or throat pain, all of whom need to undergo laryngoscopy.

6. Biopsy is the key to diagnosing laryngeal cancer. If a highly suspected patient has a negative biopsy result, multiple biopsies are required.

7. Direct laryngoscopy, microlaryngoscopy, and fiberoptic laryngoscopy.

8. Dynamic laryngoscope is used to check for early vocal cord lesions. For example, if one side of the vocal cord vibrates abnormally or vibration disappears during speech, it often indicates the possibility of early vocal cord cancer, which is also the key point in the diagnosis of laryngeal cancer.
