Hi Tina, I too had a white sore on my tongue for several months before my dentist sent me to an oral surgeon (my dentist put me on antibiotics in February) for a biopsy in April, which came back negative for cancer. The sore got worse, I finally saw a different oral surgeon who took one look at it and diagnosed it as Squamous Cell Carcinoma and made a date for surgery (diagnosis from him 05/10). Please do not let your husand wait any longer, I am not trying to be negative but time is precious, my cancer spread to two of lymph nodes in my neck and I had 1/2 of my tongue removed followed by 7 weeks of radiation. I wonder had my dentist acted quicker back in January, would I have gone through all that. Keep Looking Up!!!!God Bless!
