Syrian hamster abscess

2 days ago we noticed that our little syrian hamster has a rather big abscess on the neck under the chin. We went to the vet and they said its a tumor but also that the absces itf filled with pus and that it comes from a vaginal infection. She is 225g and 1 year and 5 months old, they said she should have surgery as she will only live a couple more months without one. Now they said that the surgery is simple but the only problem would be with the anesthesia as she may not wake up. I will attach some photos with her, any help is welcomed.

Hello - we do not diagnose on this site but a good question for your vet might be whether your hamster has a womb infection, a so called 'pyometra' and whether the abcess occurring elsewhere in the body might be related to that.  I see that this question is a few days old so hopefully this situation is now resolved, but for the benefit of others reading this;  when deciding whether to book emergency surgery for your loved one, is important to ask your vet the following questions.    1) what the rest of your pets life will look like if this isnt done.    2)  how will surgery make a difference? - what it your pets quality of life and expectancy likely to be if it is done?   3) what can go wrong.   Major surgery can have complications for example.   Treating a pyometra in a hamster (if present) would be a huge deal.   I hope that something there helps.
