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.
