Vocal cord polyps themselves are a type of benign lesion, with a very, very small chance of becoming malignant. However, if vocal cord polyps recur frequently, especially in conjunction with unhealthy lifestyle habits such as long-term smoking and drinking, there indeed exists a possibility of malignant transformation. Overall, though, this probability is relatively low, and the vast majority of cases are benign. However, in cases of frequent recurrence, it is important to watch for moderate or severe atypical hyperplasia, as this condition could potentially progress to cancer. Regular laryngoscopic examinations are needed in such cases, typically every three to six months. Additionally, it is important to avoid smoking and drinking, and to avoid excessive use of the voice.
