After working myself into a state of utter anxiety yesterday, the biopsy was really just fine. The worst part of the whole procedure is the lidocaine shots (or whatever the numbing agent is). My doctor rocks and the nurses were so nice that they even noticed I'd dyed my hair since my last visit. (They said I was "a breath of fresh air.")
But the really great news is that I was wrong: the nodule is the same as it was a year ago. It's really big, but no bigger than before. Dr. K just said that she was going to recommend an annual biopsy because that's the safest course of action. I should get results in about a week or so, but it seems like I don't have anything to worry about.
So now I am, headache and all, feeling pretty grateful. I guess that's the best thing about a day like yesterday. On a day like today I can say, "Hey, what a great day. I probably don't have cancer."
