Bobbie said she thought you had some experience with Oral cancer? I've read a lot today & it seems pretty clear there isn't a "cure" for it. I was wondering if Chemo or even Steroid shots might slow the growth & give her a bit more time?
I lost Alex to oral cancer, but really didn't have an opportunity to explore treatment.
Long story short... I suspected there was a problem. When long term sugar kitties insulin dose decreases to almost nothing or rapidly decreases or they go OTJ after years of insulin use... cancer is usually to blame. I had taken Alex in for a routine blood draw and exam prior to scheduling a dental. After discussing my suspicions as well as her insulin requirements which had fluctated some, but had reduced to almost nothing, we decided to do a biopsy the following day.
That night we said our good-byes "just in case" and I think we were both at peace. I had made a promise to Alex that I would always fight for her as long as there was always hope... as long as she wanted to fight, and we did fight... but I would never prolong her life and watch her suffer for me... because I wasn't ready to let go.
We had gone through so much together... kidney crisis, liver disease, gall stones, cholangitis/triaditis, chronic pancreatis, and diabetes... diabetes was a breeze compared to everything else. At that point, Alex had used up her nine lives and then some... and I knew she was uncomfortable.
Shortly after Alex was put under for the biopsy and possible dental, my vet called me into the room to tell me her jaw bone was so thin that he was afraid he'd break her jaw if he inserted the probe to obtain a sample for biopsy. Experience told him this was cancer. I believed him given all that had happened leading up to all this. Alex was such a trooper, but I didn't want to put her through any more. With tears in his eyes, my vet agreed it was time to let her go... and I made the decision to free her.
I'm sorry that was a long way of telling you I can't be of any help. We never had time to explore treatments. If we had, I know I would have chosen palliative care.
