I was diagnosed with squamous cell carcinoma of the tongue in April 2005. (stage 1) I had surgery with clear margins. I had a pet scan 8 weeks ago and a CAT scan 6 weeks ago and was told I was "cancer free". Two weeks ago a lymph node appeared, had it biopsied and it came back that it was cancer. I just found out yesterday so I don't know exactly what they are going to do. Does this mean I have an aggressive form of this cancer? For it to just reappear out of no where? I'm a 36 year old mother of two little ones with no risk factors. Any ideas?
