Bloop,
I would recommend that you seek the advice of a Comprehensive Cancer Center that sees 100's and 100's of patients just like you vs an ENT that maybe will see 5 a year. Here is a list:
http://www.oralcancerfoundation.org/resources/cancer_centers.htmI got 5 different opinions before I settled on Moffitt, a CCC and I am very glad I did. If I had stopped to soon in seeking answers I would either be dead today or would have had unnecessary life altering surgery.
Your cancer is nothing to take lightly and it needs to be treated properly the first time by experts who deal with this cancer all day long, every day, year end, year out.
I'm not criticizing your decision to see an ENT, I'm just trying to get you to the correct location to get the best possible treatment.
