Help give pip a second chance

Hey guys , my family and I are looking for help please.
This is Pip!
She has gained 2 huge lumps in her breasts. We can’t afford to get an MRI/CT scan , let alone the surgery to get them removed.
The vet suspects that it is more than likely cancer and hopefully if it is it hasn’t spread.
We discovered the lump mid December when she had become unwell. Turns out she had a major infection in her uterus which needed urgent surgery. She had surgery just days prior to Christmas which cost a couple of thousands dollars.
The vet said to let her heal before we think about the lumps.
Well she has healed and the lumps are getting bigger.
It’s time to get her better but we just can’t afford it right now.
We know it’s going to cost thousands :(
Please if you can help in any way it will be massively appreciated...
Especially from our beautiful girl Pip xxx
