Hi Dawn, yes I was diagnosed in my 30's with lichen planus for years looking worse and worse. Then in 2005 I got SCC on the floor of my mouth, had the floor of my mouth removed and full neck dissection. In 2009 it returned on top of my tongue, had tumor removed and did radiation. Five years now no cancer but teeth are decaying and had three teeth removed. No Cancer, but very slow to heal. So hang in there, if any questions, I am here to listen, welcome, Michele
