Kris had a residual lymph node after his rads and chemo.
It lit up on his 3 month post treatment PET, so it was removed in a Modified neck dissection. Pathology showed this to just be a necrotic node with dead SCC cells.
I would be reassured that this Lymph node is declining in size.
Glad your team will continue to keep an eye on it and you.
Enjoy the Festive Season.
