goodmorning Hap, Hang in there my friend, If you are able to continue working that is very cool, however be prepared to stop, this dreaded disease and treatment can deliver can deliver a big "uppercut", that being said you just get back up and continue the fight. You are in good company here and you will find that you are drawn back to this site time and time again, for answers to your questions and unfortunatley a wise old sage ,when it comes to oral cancers, answering questions and offering support. hang in there, Hope to see you around this site.
