The growth of the tumor would concern me. The price you were quoted from the vet seems a bit extreme to me though, have you considered a second opinion from another vet?
I do not have experience with lumps but a friend of mine has a black lab with some rather large lumps that were diagnosed as non-cancerous but they do look and seem uncomfortable.
There is a thread on this forum that lists help for veterinary bills/expenses, maybe that can help you out?
Best of luck! Keep us posted and I hope someone else can offer some advice, better insight for you!
