The clinical symptoms of laryngeal cancer will show different degrees of spread and metastasis

There are many reasons in life that can cause people to suffer from laryngeal cancer. Smoking is one of them. What are the clinical symptoms of laryngeal cancer? How can we prevent these clinical symptoms of laryngeal cancer? Next, let's take a look at the clinical symptoms of laryngeal cancer with the experts.

The clinical symptoms of laryngeal cancer can be based on the location of the tumor, with the following specific symptoms:

First, the glottic type: The clinical symptoms of laryngeal cancer are limited to the front and middle 1/3 of the vocal cords. Since the vocal cords have fewer lymphatic vessels, it is not easy to metastasize to the cervical lymph nodes. The main clinical symptom of laryngeal cancer is hoarseness, which gradually worsens. When the tumor grows larger, it blocks the glottis, and clinical symptoms of laryngeal cancer such as hoarseness and dyspnea may appear.

Secondly, the subglottic type: that is, the clinical symptoms of laryngeal cancer are located below the vocal cords. The cancer is located above the lower edge of the cricoid cartilage. Because this area is relatively hidden, it is not easy to be found in routine laryngoscopy. Because the subglottic area is blocked by the cancer, the clinical symptoms of laryngeal cancer often include difficulty breathing.

Finally, metastasis: The clinical symptoms of laryngeal cancer can be metastatic in three ways according to its degree of differentiation and primary site: direct metastasis, advanced laryngeal cancer often spreads to the submucosal infiltration, lymphatic metastasis and vascular metastasis.
