what would you do? not related to ttc or pregnancy

So my baby (dog) is almost 11 years old in human years. So getting to be old. We financially cannot afford thousand dollars vet bills. To get these tested/ X-rays done. She has this lump that's gotten bigger and a second one is forming. I'm pretty sure it's cancer. She is the very first dog I've owned. If this helps I'm in Canada and it's crazy stupid for the vets. Just for the yearly shots it's over $200.00. And I have a relative that put their dog down last year due to cancer and it costed them well over $3000.00 for x rays and blood work. It was just $1000.00 alone for the vets to put the dog down. My 2 year old daughter absolutely loves this dog out of the 5 we have. Besides the lumps she seems healthy everywhere else. Runs like she did when she was a pup. Eats and drinks well. Here are pics of the lumps and dog. She's a yorkie. First pic is the first lump.
