How to check if you suspect laryngeal cancer

What tests should be done if I suspect laryngeal cancer? Recently, I always feel a foreign body in my throat, my voice is hoarse, I have difficulty breathing and coughing up blood. I checked online and found that the symptoms are very similar to those of laryngeal cancer. I suspect that I have laryngeal cancer and want to get a diagnosis as soon as possible. So what tests should be done for laryngeal cancer? The following cancer experts will give you a detailed introduction:

1. Neck examination

This includes inspection and palpation of the laryngeal shape and cervical lymph nodes to check for laryngeal cancer. For palpation of cervical lymph nodes, the cervical lymph nodes should be checked step by step from top to bottom and from front to back according to the distribution pattern of cervical lymph nodes to find out the location and size of the swollen lymph nodes.

2. Laryngoscopy

Indirect laryngoscopy is a commonly used method for examining laryngeal cancer in clinical practice. Only when the indirect laryngoscopy examination is unsatisfactory or it is difficult to obtain pathology, direct laryngoscope and fiberoptic light guide can be used to further understand the situation of tumor invasion in the larynx, and tissue can be obtained in time for suspected lesions and sent for pathological examination.

3. Imaging examination for laryngeal cancer

(1) X-ray examination: X-ray lateral laryngeal films and anteroposterior laryngeal tomographic films can clarify the general location, size, shape of the lesion and changes in the cartilage, trachea or anterior cervical soft tissue. If necessary, laryngeal angiography can be performed.

(2) CT and MR examinations: They are helpful in determining the extent of tumor growth in the larynx, the extent of external invasion, and the status of cervical lymph node metastasis, which is especially helpful for patients in the advanced stage.

(3) Ultrasonic tomography: A method for detecting laryngeal cancer used to detect enlarged lymph nodes in the neck, determine their location and relationship with surrounding tissues, and for follow-up examinations after postoperative radiotherapy. It has the advantages of being non-destructive, convenient, accurate, low-cost, and can be performed repeatedly.
