My thyroid tumor was 4.5cm-1.8inches. That's quite a butterfly. After they excised it, it went to the lab to check which bad guy it was. I don't know what happened with the remains. Do they keep them a while, indefinitely? Do they destroy them? In the oven? Where do the ashes go then? ... For my breast tumors I had to sign authorizations so they could use the remains and some blood samples for research. Not for my thyroid. I imagine my breast tumors to be in some sterile environment, sliced and diced into specimen slides, then kept in lab drawers. For my thyroid, the image is much more obscure. I imagine it went in the oven, in a cold and desolate chamber. Dreamlike. Surreal.
