Wendy --
Why "welcome" may seem to be the wrong word right now, you truly are welcome here, and as you have already seen, there are lots of folks here to assist.
I know that feeling of devastation all too well -- as my signature shows, I also had a Base of Tongue (BOT in shorthand here) diagnosis. I did not have surgery on the tumor (though I did have a neck dissection due to spread to lymph node in my neck). Chemo and radiation eliminated the BOT tumor.
In the Blogs forum here, I have a blog that I was pretty diligent about keeping up during the treatment phases. It is called "Journey To Cancer Free -- Day Zero", and you might find it useful. Like SandySt above, I did not have many severe effects from the treatment.
My son was in his senior year of high school when I was diagnosed, and I was afraid I would not see him graduate at first. Now, he is a junior in college, and we are starting to plan graduate school visits in the Spring.
Live each day as it comes. We are all here to help.
