Laryngeal cancer


The difference between vocal cord polyps and laryngeal cancer
The difference between vocal cord polyps and laryngeal cancer is firstly notable in their nature. Vocal cord polyps are benign lesions, and their removal generally does not significantly affect the patient's quality of life or lifespan. Laryngeal cancer, as the name implies, is a malignant lesion that greatly affects both the patient's quality of life and lifespan. Location-wise, vocal cord polyps are found on the vocal cords, while laryngeal cancer can be located in one of three areas: on the vocal cords, known as glottic laryngeal cancer; below the vocal cords, known as subglottic laryngeal cancer; and above the vocal cords, known as supraglottic laryngeal cancer. The prognosis for vocal cord polyps is very good; after surgery, if the patient rests well, their future quality of life is generally unaffected. Laryngeal cancer is divided into three types: glottic, supraglottic, and subglottic, with glottic being the most common, accounting for about 80%. This type of laryngeal cancer usually presents early symptoms such as hoarseness, similar to vocal cord polyps. Therefore, glottic laryngeal cancer can often be detected early. With prompt and correct treatment, the postoperative results can be good. As it typically involves highly differentiated squamous cell carcinoma, if it is completely excised surgically and regularly reviewed postoperatively, it doesn't greatly impact lifespan or quality of life. In contrast, subglottic and supraglottic laryngeal cancers often show symptoms later, which means they tend to be diagnosed at a later stage, usually at a mid to advanced stage. Supraglottic laryngeal cancer, in particular, is prone to cervical lymph node metastasis, thus usually having a poorer prognosis compared to glottic laryngeal cancer. There's also a higher likelihood of recurrence and metastasis, and the surgery may involve greater trauma. These are the main differences.


The most common type of laryngeal cancer
At present, laryngeal cancer is classified based on anatomical location into three main types, with glottic cancer being the most common. Supraglottic and subglottic cancers are relatively less common. The primary symptom of glottic cancer is hoarseness, which can be noticeable in the early stages. Therefore, generally, the earlier the disease is diagnosed, the better the treatment outcome may be. Additionally, laryngeal cancer is also classified by pathological types. The main pathological type is squamous cell carcinoma. Overall, surgical treatment is the most important, but depending on the patient's stage and type of cancer, a combination of radiation and chemotherapy might be necessary.


The Difference Between Throat Cancer and Esophageal Cancer
Throat cancer and esophageal cancer have essential differences, starting with the specific location of the disease. Throat cancer primarily occurs in the glottis and the supraglottic area, while esophageal cancer mainly occurs in the esophagus. Typically, the symptoms of throat cancer may be more characteristic, the most common being a foreign body sensation in the throat, throat pain, and hoarseness. Particularly, glottic throat cancer symptoms are more pronounced, which might include persistent and noticeable hoarseness. The primary symptoms of esophageal cancer are pain below the neck, which may be accompanied by difficulty swallowing or swallowing obstruction. For diagnosis, throat cancer is primarily assessed via laryngoscopy, while esophageal cancer is typically evaluated through gastroscopy. In terms of treatment, the approach generally focuses on surgery, potentially supplemented by radiotherapy and chemotherapy.


What are the symptoms of throat cancer?
The symptoms of laryngeal cancer are quite varied, and there are some differences among different types of laryngeal cancer. For glottic laryngeal cancer, a common symptom is hoarseness because the cancer primarily develops on the vocal cords. This can lead to incomplete closure of the vocal cords or restricted movement during speech, causing hoarseness. Symptoms generally appear early in the course of the disease for this type. For supraglottic or subglottic laryngeal cancer, symptoms may include throat pain, a feeling of a foreign body, and difficulties in swallowing and breathing. However, hoarseness generally appears later in these cases. The primary treatment is surgery, with some patients requiring consideration for radiotherapy and chemotherapy.


Malignant treatment methods for laryngeal cancer
Laryngeal cancer is a malignant tumor of the larynx, clinically mainly squamous cell carcinoma. The treatment method for laryngeal cancer should be based on the patient's age, the pathological type of the patient, the extent of the malignant tumor, and the presence or absence of systemic metastasis. Clinical treatments mainly focus on surgery, combined with radiotherapy and chemotherapy, as comprehensive treatment methods. There may be some differences in surgical approaches for different types of laryngeal cancer, such as total laryngectomy or partial laryngectomies, which can be vertical or horizontal. Therefore, treatment should be tailored to the specific conditions of the patient. In late-stage laryngeal cancer, only palliative symptomatic treatment can be performed.


Early symptoms of throat cancer
The early symptoms of laryngeal cancer vary depending on the type, as laryngeal cancer is categorized into three types. The most common type, accounting for over 80%, is glottic cancer. The early symptom for this type is primarily hoarseness, making it the type of laryngeal cancer where symptoms appear earliest. The other two types are supraglottic and subglottic cancer. These types are less likely to show early symptoms, or the symptoms may not be typical and easily noticeable or taken seriously. The main symptom is a foreign body sensation in the throat, which is often mistaken for pharyngitis or laryngitis and not given due attention. Therefore, when experiencing persistent hoarseness or a noticeable foreign body sensation in the throat, and if throat discomfort persists, it is advised to visit the Ear, Nose, and Throat (ENT) department of a hospital promptly for an examination with an electronic laryngoscope. This can help in the early detection, exclusion, and diagnosis of the condition.


Can you eat after a total laryngectomy for throat cancer?
After the total laryngectomy for throat cancer, a period of recovery is necessary, during which time liquid food is administered via a nasogastric tube. Once recovery is complete, it is possible to eat orally. Because the entire larynx is removed during a total laryngectomy, the functions of voice and breathing are lost, and breathing is instead facilitated through a tracheostomy in the neck. Eating is completely unaffected. After recovery from the total laryngectomy, food is ingested orally, passes through the pharynx, and goes directly into the esophagus. Thus, it is possible to eat orally after a total laryngectomy for throat cancer.


Can throat cancer be contagious?
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.


Can throat cancer be cured?
Laryngeal cancer is a malignant tumor located in the larynx, which can be classified into supraglottic cancer, subglottic cancer, glottic cancer, and transglottic cancer. Any malignant tumor is not incurable; it mainly depends on how early it is detected. If laryngeal cancer is discovered early and treated correctly, promptly, and appropriately, the primary treatments include surgery, radiotherapy, and chemotherapy, among others. Under these conditions, the survival rate, cure rate, and life expectancy are quite high. However, if the laryngeal cancer has reached an advanced stage and has metastasized to other parts of the body or distant organs, the prognosis is poor, and the survival rate is relatively low.


Is T2N0M0 throat cancer serious?
Laryngeal cancer T2N0M0 refers to Stage 2 clinical staging of laryngeal cancer. Here, "T" denotes the primary lesion, typically classified as Stage 2. Stage 1 generally refers to the primary tumor, with Stage 2 lesions being larger in scope than Stage 1. "N0" indicates the local lymph nodes, showing that there is no local lymph node metastasis. "M0" indicates there is no distant metastasis. Therefore, laryngeal cancer T2N0M0 represents an early or intermediate stage. Clinically, this stage is usually most suitable for surgery, and the healing and prognosis after surgery are relatively favorable.
