I’m really sorry to hear this & I can imagine how worried & stressed you must be.
I haven’t had a ham go through surgery personally but over the years there have been quite a few members on here who have had ham undergo surgery for tumour removal & most often they do seem to do well.
There are some things to consider though, the older the ham the harder it is for them to cope with an operation & recover well but older hams can do well so in’t unheard of.
Anaesthetic is always a risk for such a small animal.
where the tumour is & what it’s attached to will also be a factor in whether surgery is appropriate or not & the chances of making a good recovery so there is a lot to discuss with the vet there.
I hope surgery is an option & your ham recovers well, if not an option then you might want to discuss pain killers if necessary & ways to keep her comfortable if she is able to continue to live with the tumour for some time.
