My cat has a fatty lump that's grown bigger and firmer. Is it cancer?

Pet's info: Cat | Domestic Longhair | Female | spayed | 3 years and 4 months old | 12 lbs

Hello, I am really worried about my female feline Jeepers. She is a plump kitty and had a common fatty lump, confirmed by her vet in the past. This lump has been located on her undercarriage lower level nearby her right back leg. I was petting her and felt that it had become bigger and a little more firm. I pushed on it and she shows no signs of discomfort or pain. Could this be cancer? I'm so worried.

Lipomas are benign but they can grow larger. It's recommended to have them removed surgically if they start bothering the cat, get really big, and/or impede their movement. Since this lump is getting bigger, I'd take Jeepers back into the vet to have it checked out. Best of luck.
