Help with cost of front left leg amputation

Hello everyone
This is my dog Cae. I’m a patterdale cross jack Russell. I am a very sociable dog and a massive personality. About a month ago I had a lump come on my left front leg, I went to the vets and had a couple of biopsies but it was inconclusive. The vets on one time said that it was a tumour. I had to have a procedure to take a piece of the tumour itself to be analysed to see if it is cancer or not. That is where I am now. Could anyone help in anyway with funds that would be greatly appreciated and will update when I get the results.
