Queen's Cyst Removal

I've had Queen for 4 years, she found me when she was about 1 or 2, after being bought and sold multiple times, to multiple families. People didn't like her because they said she was mean and unsociable, but that just made me want her more. Queen is unrecognizable now from the hedge she was then , shes friendly, loves being held, having playtime,  and absolutely loves giving kisses.

a month ago I took her out of her cage and noticed a small bump on her side. When I ran my hand across it I could tell it was really sensitive so I immediately made an appointment to get it checked out. They did xrays and told me it was a cyst that currently wasn't penetrating her body and that her lungs were clear but they did recommend surgery.
They gave me the estimate of anywhere between 600 and 900 dollars depending on how the surgery goes. 

A few people have even insinuated that it may not even be worth it because of her age and the average lifespan of hedgehogs being so short, but she's been with me through so much I can't just do nothing. She's helped me so its my turn to help her.
