What are the diagnostic methods for laryngeal cancer

Nowadays, laryngeal cancer is a common malignant tumor in the otolaryngology department. Today we are going to prepare for you about the diagnosis method of laryngeal cancer. We hope that our preparation today will be helpful to you. Let's take a look at this knowledge together.

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. Not easy to metastasize to cervical lymph nodes

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. Under laryngoscope, the tumor is cauliflower-like, ulcerative, nodular or mass-like, etc. 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 main basis for the diagnosis of 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 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.

The above is the diagnostic method for laryngeal cancer that we have prepared for you today. We hope it can be helpful to you. If you have any other needs, please consult online experts. We are always here to answer your questions.
