Shirlock3,
My two cents worth too: do get it checked asap. I know how hard it is, I waited a month with a lump at my neck, not wanting to consider the possibility of cancer. I never even said the word until the doctor told me what it was. I hope your will turn out to be a false alarm. But it is an alarm, and you have to demand that you get attention.
I hope you'll have good news. Let us know>. And I am so glad you stopped smoking. You addad years to your life, and to your quality of life, regardless of what the bump turns out to be.
