What are the methods for checking laryngeal cancer?

In recent years, laryngeal cancer has become a major disease that endangers human life. It has brought great pain and distress to mankind. Do you know how to check for laryngeal cancer? The following experts will introduce us to the examination methods for laryngeal cancer.

1. CT scan and X-ray examination: can assist laryngoscopy, X-ray lateral plain film, and anteroposterior tomography. To clarify the location, size, range, shape, and cartilage involvement of the tumor. CT scan can further observe whether the laryngeal space and epiglottic cartilage are invaded by the tumor, providing the scope and location for surgery.

2. Laryngoscopy: It can observe the changes in the larynx and the activities of the vocal cords and epiglottis. It can detect whether there are neoplasms, ulcers, etc. in the local area. There are direct laryngoscopes, indirect laryngoscopes and fiber laryngoscopes. It can also observe the location, shape and size of the tumor, and can take living tissue for pathological examination. Therefore, laryngoscopy is an important means of diagnosing laryngeal cancer. Ulcers, etc., can also observe the location, shape and size of the tumor. If it is a pyriform sinus cancer, it can be seen that the pyriform sinus on both sides is asymmetrical, there is cauliflower-like cancer tissue in the pyriform sinus on the affected side, and there is saliva retention or food residue accumulation; posterior cricoid cartilage cancer is not easy to detect in the early stage, and cancerous lesions in the cricoid cartilage plate can be seen in the late stage. If there are ulcers or granulation tissue on the surface, it is mostly laryngopharyngeal posterior wall cancer. Through the fiber laryngoscope, living tissue can also be taken for pathological examination. Therefore, laryngoscopy is an important means of diagnosing laryngeal cancer.

3. Biopsy: It can confirm the diagnosis of laryngeal cancer. If multiple biopsies are negative, a biopsy can be performed through laryngoscope for pathological examination. However, if laryngeal cancer cannot be ruled out, a laryngeal fissure biopsy can be performed.

The above is the examination method for laryngeal cancer introduced by experts.
