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 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.

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 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.

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.

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.
