Just a follow-up on my girl.
We met with the oncologist today. Even though her last surgery had incomplete margins, there is still only about a 30% chance of the tumor coming back, and a 70% chance it won't. If it does recur, we would feel it as a lump along the scar from the previous removal. Since this grade has a very low risk of metastasis and moving to other organs or areas, they recommended we just wait and watch, feeling her skin regularly for any signs of recurrence. If we do feel it return, she will have a second surgery removing 2cm of skin around the entire previous scar. So as long as we detect any bumps early, it's a low risk of spreading and is in a great location if she needs the surgery because the skin on her neck is very elastic and there is a good bit of extra. Chest x-rays showed clear lungs as well, which is the most common location for metastasis.
So all things considered, about the best news we could hope for given the situation, and we can hopefully breathe a bit of a sigh of relief over the holidays.
