Laryngeal cancer


Symptoms and Early Signs of Throat Cancer
Symptoms and signs of laryngeal cancer in patients mainly vary according to the different locations of the tumor in the larynx. Most patients with early-stage laryngeal cancer experience a foreign body sensation in the throat, which can be persistent. Patients may even feel a choking sensation when swallowing. Additionally, some patients with early-stage laryngeal cancer may experience unexplained hoarseness or coughing and choking when drinking water, and these symptoms generally do not respond well to oral medication. Some patients exhibit frequent coughing, and ordinary symptomatic cough treatments are ineffective. These are mostly early symptoms and signs. As the laryngeal cancer progresses, patients will experience a noticeable obstruction in the throat, along with symptoms like difficulty breathing.


Can throat cancer be detected by a CT scan?
Most laryngeal cancers can be detected through CT scans because, during the scan, it is possible to see whether there are neoplasms in the area of the pharynx and larynx, especially around the laryngeal cavity, ventricle, and vocal cords. Generally, if there are any growths, they will be visible on a CT scan. However, some early-stage laryngeal cancers, where the mucosa has just started to show changes, might be missed by CT scans. In such cases, it is generally recommended to also perform a laryngoscopic examination. If possible, conducting an NBI (Narrow Band Imaging) laryngoscopy could reveal early mucosal changes. If early-stage laryngeal cancer is confirmed by pathology, surgical or radiation treatment can be very effective and generally has a low chance of recurrence.


Throat cancer coughing up blood, what is going on?
Patients with laryngeal cancer may experience bleeding due to the rupture of local tumors. The surface tissue of tumors that develop in laryngeal cancer is relatively fragile, and may rupture and cause bleeding during stimuli such as eating or coughing. When these symptoms occur, it is crucial to visit a hospital for medical consultation immediately. Examinations like indirect laryngoscopy and electronic nasopharyngoscopy can help confirm the patient's symptoms and make an accurate diagnosis. Under the guidance of a physician, hemostatic drugs, antibiotics, and hormones can be used for temporary symptomatic treatment. Patients with laryngeal cancer should be detected and treated early, undergo surgery as soon as possible, and receive radiation and chemotherapy to ensure their survival.


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 to self-examine for throat cancer
Throat cancer is a common malignant tumor in otolaryngology, and patients with throat cancer usually have no obvious early symptoms. If a patient exhibits symptoms such as hoarseness and difficulty swallowing, it should be taken seriously, especially in patients with a long history of smoking. At this point, it is important to seek medical attention promptly, complete inspections using electronic laryngoscopes, a CT scan of the throat, and other relevant examinations to make a clear diagnosis. For patients with neoplasms in the throat, a pathological biopsy is necessary to determine the type of pathology. The most effective treatment method for throat cancer patients is early detection and early treatment, which can avoid surgical operations through early laser surgery, thus reducing the pain and trauma for the patient.


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.
