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.

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.

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.

What should I do about edema from radiation therapy for throat cancer?

After radiotherapy for laryngeal cancer, or during the process of radiotherapy, edema may occur, mainly mucosal edema in the pharyngeal region, and some patients may also experience swelling of the soft tissues in the neck. In such cases, it is recommended to visit an otolaryngology department where a laryngoscopy and routine blood tests can be conducted to help assess the severity of the condition. Generally, nebulizer therapy can be chosen. If there is an accompanying acute bacterial inflammation, antibiotics may need to be considered. Most patients will see a gradual reduction in the degree of swelling after timely medication treatment, but overall, complete recovery requires a relatively long period of time.

Can early-stage throat cancer be cured?

If we are talking about early-stage laryngeal cancer, generally speaking, the cure rate is relatively high. The main treatment methods for early-stage laryngeal cancer are primarily surgical, although radiation therapy can also be considered for some patients. However, specific treatments still need to be tailored according to the patient's own condition and the pathological staging and typing. If the cancer is well-differentiated, the treatment outcomes are generally better. If it is poorly differentiated or moderately differentiated, even though it is early-stage laryngeal cancer, the cure rate is relatively lower, especially within the first two years and the first five years. If a five-year survival rate is achieved without evident recurrences or metastases, this is considered a standard for clinical cure. However, regular follow-ups are still necessary due to the potential risk of recurrence.

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.
