Please don't stop your treatment. You say that the swelling or lumps have disappeared and that sounds like progress to me which makes it all the more important for you to continue your treatment! Please give us more information and try to answer the questions above. There are many here who have had similar experiences to yours and can help you get through the difficult days. There is a world of helpful information available if you check out the main pages (see upper left and click on Oral Cancer Foundation). It will help you to think of questions you can ask your doctor or for anyone here. Let us hear from you soon!
