A vocal cord polyp is a clearly delineated mass that is not cancerous or precancerous. However, polyps and cancer are sometimes difficult to distinguish and can only be determined by pathological examination after removal. First of all, in terms of the pathogenesis of vocal fold polyps, it is now relatively clear that they are the result of acoustic trauma, physical pressure on the vocal folds caused by excessive vocalization or vocalization in a hostile environment. These causes of pathogenesis do not cause cancer. Further, in terms of how vocal fold polyps grow, a polyp is usually a red lesion with distinct borders and is clearly distinct from the surrounding tissue. It can be either broad-based or narrow-necked. It can be smooth and round or bladed. Some polyps that have been present for a long time can take on strange shapes and can vary greatly in actual size. Polyps usually occur individually, but they can also occur in pairs, with polyps on each vocal cord opposite each other. They are most often found at the midpoint of the vocal folds. Vocal fold polyps are generally slow growing. These appearances and distribution patterns suggest that vocal fold polyps are a benign lesion in growth. The main reason why polyps may be considered to be cancerous is because polyps and cancer themselves are sometimes difficult to distinguish. Vocal fold polyps in the strictest sense usually do not have any tendency to become cancerous. In other words, cancerous tissue found on the vocal cords is not a polyp and is mistaken for one. When polyp-like swellings on the vocal folds are found to be fast growing, irregular in shape and showing infiltrative growth, it is important to perform pathological examination as early as possible. To identify whether these vocal fold swellings are polyps or cancer. Vocal fold polyp itself is a benign disease and it does not have the possibility of malignant transformation. It is important to be alert to the fact that the appearance of some cancers cannot be distinguished from polyps. Pathological examination is needed to avoid misdiagnosis.
