Took Jezebel back in and the vet said he could definitely see the problem. Last week it looked like scar tissue but this week it is quite large. They did an aspiration biopsy (quick swipe of a swab) and looked at it under the microscope. Lots of white blood cells, as expected since there is clearly an infection of some sort. There
were a couple of clumps of fast dividing cells which could indicate cancer or just healing tissue. Of concern was that there were a lot of "dark" cells in the mix - dark suggesting that they were pigmented which goes back to melanin - which suggests melanoma. There was a wide area of the dark cells ringing right where the original tumor was which suggests a lot and the suggestion isn't good.
He put her on a round of antibiotics for the infection but thinks she needs to go back to the oncologist. He is calling the oncologist on Monday to discuss and we'll take it from there.
What can I say? We'll take it a day at a time.
