We had a cat that had a lump like that in his armpit. It even had the same little dark dimples. The vet just said keep an eye on it. It didn't change for a few years, then in a matter of weeks it grew to the size of a golf ball. We had it removed and he came thru the surgery fine, but died 2 days later. He had diabetes which was getting pretty bad and he was 11 so I chose not to have a biopsy done to see if it was malignant. Please, have it checked ASAP. It looks identical to the one Snuffy had. |
