What are the symptoms of laryngeal cancer and how to diagnose it?

Depending on the type of laryngeal cancer, the onset of symptoms and the severity of the disease may vary. Let's learn about laryngeal cancer together.

(1) Hoarseness: It is the earliest symptom of vocal cord cancer. It is usually persistent and gradually worsens. The early symptoms of subglottic cancer are not obvious, while hoarseness is a symptom of the later stage.

(ii) Foreign body sensation and pain in the throat: This is often an early symptom of supraglottic cancer. After the cancer ruptures, throat pain may occur, sometimes radiating to the ear on the same side. This is a late symptom.

(III) Coughing and blood in sputum: These symptoms occur after the cancer has ruptured and are common.

(IV) Difficulty breathing: This is a symptom of the later stage, indicating that the cancer has developed to the point of blocking the throat.

(V) Cervical lymph node metastasis: It can metastasize to the middle deep cervical lymph nodes on the same side, and may metastasize to the contralateral side in the late stage.

There are three different types of cancer, depending on where the cancer is located.

(I) Supraglottic type

(ii) Glottal type

(III) Subglottic type

Stages of Laryngeal Cancer:

The letter T represents the size of the tumor and the extent of invasion of the primary tumor. T1: The tumor is limited to one side of the larynx; T2: The tumor is located on both sides of the larynx; T3: The tumor has caused obstruction of the movement of the vocal cord on one side; T4: The tumor has invaded outside the larynx.

N indicates whether there is lymph node invasion, which is divided into 4 levels, namely N0, N1, N2 and N3. NO: There is no evidence of lymph node metastasis; N1: There is a suspicious lymph node with a diameter of less than 3 cm; N2: Lymph nodes are found on both sides of the neck or there are more than two lymph nodes on one side, or the diameter on one side is greater than 3 cm and less than 6 cm; N3: A lymph node is more than 6 cm in diameter,

The letter M indicates whether there is distant metastasis, M0: no metastasis; M1: metastasis;

The TNM staging system is combined to form the stage of laryngeal cancer:

Stage I: T1, N0, and M0;

Stage II: T2, N0, and M0;

Stage III: T3, N0, and M0; T1, T2, or T3, and N1, M0;

Stage IV: T4, N0 or N1, M0; any T plus N2 or N3 and M0, or M1 plus any T or N;

When the tumor is very small, it is T1. When distant metastasis occurs or invasion of adjacent structures (but not including lymph nodes) occurs, it is T4. Laryngeal cancer that has invaded the lymph nodes and reaches N2 or N3 is also T4.
