Hi, I am a 54 year young lady and in 2002 I was diagnosed with invasive squamous cell carcinoma in my righr sinus cavity. After my face was layed open and tumor removed then went through 29 radiation treatments, and all has been great until a few weeks ago I have started having simular symptons and I waterpick sinus cavity now at least 3-4 times a week. Any suggestions? Thanks,Robbin

Summarized question: can squamous cell carcinoma be back after few year?
