I think I may be freaking out but as I have just finished my radiation treatments in November I didn't think this was possible. I found a small mass on my gum yesterday. It looks just like what I had before. Please tell me it is not possible for the cancer to show up again this fast. I mean I know I am going to the onocologist Monday but I am totally stressing. I need to hear from my friends here that have gone through all this junk as well. I will keep up here after I see the onocolgist to let you know what he says. But what I want to know is has anyone had a reacurrance (no spell check here sorry) this fast????
