Q: Can oral lichen planus lead to oral cancer?
A: This association remains controversial, but there are reported cases of this occurring. This concern reinforces the essential need to obtain an accurate diagnosis, typically with a biopsy. All patients with oral lichen planus should have a periodic evaluation to asses the efficacy of therapy and to monitor for suspicious changes. If your oral lichen planus does not respond to treatment or if you should notice a significant change, you should contact your heath care provider for further evaluation.
