Laryngeal cancer
Is throat cancer easy to treat?
Laryngeal cancer is a malignant tumor in the larynx, clinically mainly squamous cell carcinoma. Currently, the main treatment is comprehensive treatment centered around surgery, including surgical radiation therapy and chemotherapy. Laryngeal cancer can be completely cured if detected early. It is divided into three types: supraglottic, glottic, and subglottic cancer. Glottic cancer, due to the early and noticeable symptom of hoarseness, is usually detected early, thus the clinical treatment outcomes are relatively good. Therefore, laryngeal cancer is among the malignant tumors with relatively good treatment outcomes, and is considered relatively easy to treat. In summary, the current treatment outcomes for laryngeal cancer are still quite good.
Common sites of laryngeal cancer
Laryngeal cancer is a malignant tumor in the larynx, and clinically, it is primarily squamous cell carcinoma. There are several types of laryngeal cancer: firstly, glottic cancer; secondly, supraglottic cancer; there is also subglottic cancer, and transglottic cancer that spans two regions. Among these types, glottic cancer is the most common. Early-stage glottic cancer is generally detected earlier due to hoarseness, and the outcomes after surgery are relatively better. Consequently, the most frequently diagnosed site of this disease is the vocal cords. After surgery, regular follow-up appointments are necessary to monitor and observe the healing process post-operation.
Can you speak after laryngeal cancer surgery?
Laryngeal cancer is a malignant tumor of the larynx, and the clinical treatment is mainly surgical, including radiation therapy, chemotherapy, and comprehensive treatment. Whether one can speak after surgery depends on the method of the surgery. Total laryngectomy renders the patient unable to speak. We can help the patient speak through esophageal speech, electronic larynx, and other assistive devices, but there is a significant difference in the sound quality and volume compared to normal speech. With partial laryngectomy, depending on the specific situation, the patient may be able to speak, but the quality of speech still differs greatly from normal speech. Overall, it depends on the condition of the laryngeal cancer and the surgical approach.
Is a hoarse voice an indication of throat cancer?
Hoarseness does not necessarily indicate laryngeal cancer because there are many diseases that can cause hoarseness. Common ones include vocal cord nodules, vocal cord polyps, acute laryngitis, chronic laryngitis, vocal cord grooves, and laryngeal cancer. The primary approach should be to visit an ENT (Ear, Nose, and Throat) department in a hospital, undergo an electronic fibrolaryngoscopy, and then determine the specific lesion based on the examination results. It is incorrect to diagnose laryngeal cancer based solely on hoarseness. For instance, some types of laryngeal cancer, such as supraglottic or subglottic, may cause hoarseness symptoms to appear late or even not at all. Therefore, while hoarseness does not necessarily mean laryngeal cancer, laryngeal cancer can potentially cause hoarseness. It is crucial to seek timely medical attention and undergo electronic fibrolaryngoscopy for a basic definitive diagnosis when hoarseness occurs. Apart from diseases of the throat, conditions affecting the thyroid, mediastinum, and esophagus can also cause hoarseness when they progress to a certain stage. Thus, hoarseness is a symptom that can be caused by many diseases, but it is not necessarily indicative of laryngeal cancer. Supraglottic laryngeal cancer, however, can manifest hoarseness as an early symptom. Therefore, it is critical to seek medical attention promptly once this symptom occurs.
What is throat cancer diagnosed through?
Laryngeal cancer is a relatively common disease in otolaryngology. It is divided into several types, such as glottic cancer, supraglottic cancer, subglottic cancer, and transglottic cancer. The clinical diagnosis of laryngeal cancer first requires a medical history, such as a long-term history of smoking and viral infections. Clinically, patients may present with chronic hoarseness and physical examinations can reveal tumorous tissue growth. Additional diagnostic tools include the use of a laryngoscope, as well as CT or MRI imaging studies. The most crucial standard for definitive diagnosis is the examination of pathological tissues, specifically biopsy. During the clinical diagnostic process, it is also necessary to differentiate between laryngeal cancer and conditions that may present similarly, such as laryngeal papillomatosis, to definitively diagnose laryngeal cancer. This outlines the clinical diagnostic procedure for laryngeal cancer.
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.
What are the symptoms of early-stage throat cancer?
The early symptoms of laryngeal cancer vary: some people exhibit typical symptoms while others show atypical symptoms or even no symptoms initially. For glottic laryngeal cancer, one of the earlier symptoms is hoarseness. This type of cancer occurs in the vocal cords area, which can affect closure of the vocal cords during speech, causing hoarseness. Some patients may also experience throat pain, abnormal bloody discharge from the throat, or have difficulties in breathing and swallowing, which could all be symptoms of laryngeal cancer. However, some patients may not show any symptoms in the early stages, especially those with supraglottic or subglottic laryngeal cancer, where early symptoms are not typical. Symptoms might only appear in the mid to late stages. Therefore, it is necessary to use a laryngoscope for examination and to perform a neck CT for a comprehensive evaluation.
Difference between the symptoms of laryngitis and throat cancer
There is a fundamental difference between laryngitis and laryngeal cancer. Laryngitis is an inflammatory infectious disease, mainly caused by bacterial infection or chronic inflammatory conditions, clinically characterized primarily by hoarseness. Treatment is mainly through medication, such as oral medications or nebulized inhalation therapy. Laryngeal cancer is a malignant tumorous disease, primarily squamous cell carcinoma. Clinically, in addition to hoarseness, we can also observe tumorous lumps and swelling of the cervical lymph nodes, which are manifestations of malignant tumors. The treatment of laryngeal cancer primarily involves comprehensive treatment led by surgery, including surgery, radiotherapy, chemotherapy, and some biological treatments, etc. Therefore, there is a fundamental difference between the two.
The difference between esophageal cancer and laryngeal cancer
Esophageal cancer and laryngeal cancer are both malignant tumors. Esophageal cancer refers to the malignant tumor occurring in the esophagus, while laryngeal cancer refers to the malignant tumor occurring in the larynx. Therefore, their tumor locations are different. The pathology of both is generally squamous cell carcinoma. The main symptom of esophageal cancer is obstructed eating; patients will feel difficulty swallowing, obstruction, and worsening of these symptoms as they eat. The primary symptom of laryngeal cancer is typically a hoarse voice, which distinguishes the symptoms of the two cancers.
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.
