Follow the experts to understand the main diagnostic points of laryngeal cancer

To avoid the trouble of laryngeal cancer, people must do a good job of preventing laryngeal cancer in daily life. So what are the key points in diagnosing laryngeal cancer? Many people don’t know. Now, experts will introduce the key points in diagnosing laryngeal cancer to you so that everyone can take preventive measures.

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 cervical lymph nodes.

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 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. Patients with hoarseness for more than 4 weeks, age over 40, or throat discomfort, foreign body sensation, or throat pain all 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 are also key points in the diagnosis of laryngeal cancer.

8. Dynamic laryngoscope is used to examine 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.

Through the above introduction, everyone should have some understanding of the key points of laryngeal cancer diagnosis. I hope it can bring some help to everyone. I wish that patients can choose the treatment method that suits them as soon as possible and recover soon.
