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 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.

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.

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.

Can throat cancer be cured?

Throat cancer is a relatively common type of head and neck malignancy with a high clinical incidence. Most patients require surgical treatment, and some need comprehensive treatment combining radiotherapy and chemotherapy. Generally, patients diagnosed in the early stages have better treatment outcomes and higher five-year survival rates. Typically, achieving a five-year survival rate after standardized surgery or radiotherapy and chemotherapy is considered a clinical cure. However, the proportion of patients in the middle to late stages achieving this is relatively low. Therefore, regular follow-ups are necessary to monitor the recovery process, regardless of the stage or type of the disease.

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.
