Epithelial dysplasia must be treated

We read with great interest the article titled, "Should severe epithelial dysplasia be treated?" by Zhang et al. [1]. We appreciate the authors' efforts to find an answer to this most difficult question in the field of oral oncology, and would like to share our views on this subject. While supporting Zhang et al.'s views on treating severe epithelial dysplastic lesions, we believe that all epithelial dysplastic lesions, irrespective of severity (i.e., mild, moderate, or severe), demand attention.
