Laryngeal cancer is a malignant tumor of the larynx, which is clinically primarily squamous cell carcinoma and belongs to epithelial malignancies. Generally, epithelial malignancies are not contagious. However, laryngeal cancer may sometimes be related to certain viral infections, such as papillomatosis, which might be contagious. This is an aspect of its etiology, but laryngeal cancer itself is not contagious. In summary, laryngeal cancer is not contagious. It is a malignant tumor disease, and its clinical treatment mainly involves surgical intervention, which can be supplemented with radiation therapy and other treatments.

How to diagnose throat cancer

Laryngeal cancer examinations are mainly divided into two categories. The first category is laryngoscopy, and the second is imaging studies. Laryngoscopy is further subdivided into fiberoptic laryngoscopy, electronic laryngoscopy, and indirect laryngoscopy. Indirect laryngoscopy is relatively rudimentary and generally doesn't play a significant role in diagnosing laryngeal cancer. Therefore, fiberoptic or electronic laryngoscopy is typically preferred as these methods can directly determine the presence of neoplasms in the throat. If a neoplasm is detected, further pathological biopsy testing can be considered. The other method is imaging studies, primarily involving CT scans or MRI of the throat. These are helpful in determining the size, extent, and preliminary nature of the throat neoplasms. Combined with the above methods, a definitive diagnosis can generally be established.

How is laryngeal cancer diagnosed?

In clinical settings, the diagnosis of laryngeal cancer primarily relies on several aspects. Firstly, the patient's history, such as a family history of laryngeal cancer, and whether there is a long-term smoking history, for example, smoking two packs a day. Secondly, we need some clinical data, such as whether the patient exhibits symptoms like hoarseness. Then, during physical examination, we need to check for the presence of cancerous tissues in the hypopharynx, vocal cords, and the subglottic cavity, such as the presence of lumps, uneven surfaces, erosion, ulcers, etc. These are its symptoms and signs. Furthermore, we can utilize some auxiliary examinations, such as laryngoscopy, which allows direct observation of the tumor tissue. However, the definitive test involves taking a sample of the tumor tissue for a biopsy, identifying the presence of tumor cells, i.e., cancer cells. This result serves as the basis for confirming a diagnosis of laryngeal cancer. Of course, other auxiliary examinations like CT scans and MRI can also assist in diagnosing laryngeal cancer.

The difference between laryngeal cancer and pharyngeal cancer

The main difference between laryngeal cancer and pharyngeal cancer lies in the different parts they affect. Laryngeal cancer occurs below the level of the epiglottis, while pharyngeal cancer generally occurs above this level, including tumors in the pharynx, tonsils, and base of the tongue, whereas laryngeal cancer primarily involves the vocal cords and the lower pharynx. For the diagnosis and treatment of pharyngeal and laryngeal cancers, we can use nasoendoscopy, paranasal sinus CT scan, and CT scan of the larynx among other examinations to make a clear diagnosis, and a pathological biopsy for final confirmation. Once diagnosed, it is usually necessary to surgically remove the tumor promptly to achieve a cure.

What department should I go to for throat cancer?

Laryngeal cancer is a malignant tumor of the larynx. Therefore, initially, one should consult the otorhinolaryngology department. However, in some specialized hospitals, such as cancer hospitals, there might not be a specific otorhinolaryngology department, but there is a head and neck surgery department, so in that case, one should consult the head and neck surgery department. After surgery for laryngeal cancer, comprehensive treatment including chemotherapy and radiotherapy is required. Thus, post-surgery, if radiotherapy is needed, one should visit the radiotherapy department, and if chemotherapy is needed, one should visit the oncology department. Generally, the decision for surgical, radiotherapy, and chemotherapy treatments is based on the condition of the disease.

Where is throat cancer likely to metastasize?

The metastasis of laryngeal cancer primarily involves local spread, mainly to the lymph nodes in zones 2, 3, and 4 of the neck. When the cancer becomes more severe, it can break through the lymphatic vessels and spread to the liver, kidneys, spleen, brain, lungs, and other related areas. Laryngeal cancer is a malignant tumor of the pharyngeal region, typically caused by long-term smoking, drinking, immunodeficiency, and cellular mutations. It commonly occurs in the vocal cords, esophagus, laryngeal ventricle, piriform sinus, base of the tongue, and epiglottis. It causes patients to feel a foreign body sensation in the throat, persistent hoarseness that progressively worsens, irritative cough, difficulty swallowing, and difficulty breathing. An examination with an electronic laryngoscope can help diagnose the condition. If an abnormal mass is found, a local biopsy is necessary. If laryngeal cancer is confirmed, related surgical treatment as well as radiotherapy or chemotherapy may be required.
