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.
