The Senior Vet mentioned that cancer usually starts spreading when we start doing invasive tests so he recommended to do a punch biopsy to minimize movements and refrain from aggravating the cancer cells, if that's what it is. There is also a possibility that Adenoma can become cancerous too.
Charlie was a good boy and allowed the vet to do the punch biopsy without fuss. He had to be fasted for the morning and his mind was probably on his meal after the tests!! You can see a tiny hole that was punch on the lump on his tail.
The results will be out in 10 days' time, we hope its nothing serious. Although with Charlie's age at 15 yrs old, there really isn't very much we can or want to do if anything at all, but to make him as happy & comfortable as he can till he rests forever.
The vet visit must have stressed poor Charlie out and he had a 3 minute seizure when he got home.
His vet bill cost $500 and any help would be very much appreciated. Please email firstname.lastname@example.org. Thank you.
