My senior cat has a recurring lump after surgery. What should I do?

Pet's info: Cat | Mixed Breed | Female | spayed | 13 years and 10 months old | 7 lbs

Hi. I have a 13 years old cat. Earlier last year she started growing a lump in the middle of her body on the right side. It grew quickly. The vet said they could not determine if it was cancerous or not. She ended up having surgery. Unfortunately, she grew a lump again, quickly. This time the lump is a bit harder than the last time. The vet said her body needs to "clean out" but how is it cleaning out by growing another lump? Does she need another surgery? What do you think is going on? Help.

In this case it is very likely that the tumor is aggressive and it is coming back. To be able to give you a specific answer in this case, I would need to have more informations about the tumor (name of it if it was analyzed after removal) and other clinical investigations that have been done (if any).
