My dog has a growing, non-painful lump on her stomach. Is it cancer?

Pet's info: Dog | Jack Russell Terrier | Female | spayed

Hi! My dog has a small round lump on her stomach just below her ribs. It has grown quite a bit but doesn't seem painful when it is touched. She is also still her natural happy healthy self. But a part of me is very worried it is cancer. Do you have an explanation for this? Thanks!

It could be a benign or cancerous mass, and abdominal hernia, or an abscess or seroma. I would recommend that you have Toffee examined by a vet. The vet may take a sample with a needle for examination under the microscope to help get a diagnosis and treatment plan.
