If you have symptoms of laryngeal cancer, you should seek treatment in time

There are many diseases in the larynx. I believe everyone should know something about laryngeal cancer. It is also good to know more about the symptoms of laryngeal cancer . Now, let's learn more about laryngeal cancer from the following article.

1. Laryngeal cancer confined to the vocal cords is more common in the anterior and middle thirds of the body, is well differentiated, and is classified as grade I or II. It develops slowly, and is not easy to metastasize to the cervical lymph nodes due to the small number of lymphatic vessels in the vocal cords. The symptoms of laryngeal cancer are hoarseness, which gradually worsens. When the tumor grows larger, it blocks the glottis, causing laryngeal wheezing and dyspnea. Symptoms of advanced laryngeal cancer include bloody sputum and laryngeal obstruction.

2. Subglottic type: This is a special laryngeal cancer with symptoms of cancer located below the vocal cords and above the lower edge of the cricoid cartilage. Because this area is relatively hidden, it is not easy to find in routine laryngoscopy. Patients with early laryngeal cancer may be asymptomatic, but later they may develop coughs and bloody sputum. In the late stage, because the subglottic area is blocked by cancer, laryngeal cancer patients often have difficulty breathing and may penetrate the cricothyroid membrane, invade the thyroid gland and anterior soft tissue, and may also infiltrate along the anterior wall of the esophagus. These are all typical symptoms of laryngeal cancer.

In summary, the symptoms of laryngeal cancer are usually described above. I hope it can help everyone understand the knowledge of laryngeal cancer and cure it in time. If you have other questions about laryngeal cancer, you can contact our online experts to answer your questions.
