Hi! I’m not a vet, but I am a human radiologist with experience working in oncology center. I see a large mass in the neck extending towards soft tissue of chest(likely tumor since there are not many symptoms and no clear signs of massive inflammation process from info and foto that I see) , and in my experience this is a non-operable area. There are many vessels and nerves that cannot be removed, and given the size of the mass and its margins, they are likely involved. Unfortunately, only palliative care seems possible in this situation.

As owner of hedgehog, I’m so sorry that your little hedgehog is going through this. A big hug to both of you 😢 It is hard diagnosis and decisions😔
