Hi everyone, we received some bad news about our older cat Tikka. Two weeks ago, we brought Tikka in to our local vet due to slight increased thirst/urination, since we were worried about onset diabetes. While doing her usual examination, our vet discovered a growth on near her lower mammaries. The cytology test was consistent with cancer, but did not fully confirm it (epithelial neoplasia with significant atypia). However, she also had a chest x-ray, which showed some signs of metastasis in her lungs and potentially lymph nodes, so the signs are pointing to mammary cancer.

We have an upcoming appointment with our usual internist, as well as a new oncologist. We plan on asking for a new x-ray, as well as an ultrasound. We plan to discuss options and the game plan going forward. In addition to this new condition, she also has IBD/SCL, CKD, recurrent UTIs, and also is currently underweight. Obviously, we have a lot of questions.

Given that there are some signs of metastasis already, is it necessary to perform a biopsy? We don’t want to have her put under, or have her in pain, if it isn’t necessary. Would knowing more about the cancer affect the chemo drugs administered? Also, we’ve seen advice that surgery may not be advised is the cancer has already metastasized, which there are signs of on the x-ray, but in that scenario is it also advised not to do chemo? We do know that chemo usually works better when there is also surgery involved.

Were there any other online resources you found helpful? Also, this may be a painful question, but how long did your cat live after their initial diagnosis? Was there anything unexpected that helped them through the process, such as a supplement or something self-care related?

Also, any advice on finding a palliative care team for pain management/end of life stuff? Are there specialists for palliative care, or does that fall under another category such as internal medicine? Our local BluePearl branch didn’t have anyone listed for that particular specialty.

Any advice or input is appreciated! We can also provide blood/urine test results if that would help.

I'm so sorry to hear this and bless you for taking such good care of your cat. One of the vets involved should be able to advise and possibly provide something for comfort measures without having to bring in someone who specializes in palliative care. Yes, chemo is determined on a number of factors and does not always require a surgical intervention to make it more effective. However, it does make most people sick. (Sorry, I know more about people.)

I have had three cats with cancer each with situations that were incredibly different. The youngest had lung cancer, and from the intial diagnosis at the emergency animal hospital, he went so fast. (He started having difficulty breathing, with no previous signs or symptoms.) We had him put to sleep at our regular vet's office. We were completely blindsided. When we took him to the emergency vet, we thought he was having an asthma attack.

I apologize for not being able to give you more insight. You obviously love her very much. I wish I could help. Please keep us updated.

Cats usually respond to chemo better than humans. I had a cat with SCL on chlorambucil, as do some members with currently living cats, and most tolerate it well. I apologize if I am not remembering correctly, but I had thought that one of your cats was on chlorambucil a while back, so you have experience with that. Mammary cancer is not something that I have had to face with a cat. My GSD had immunotherapy for melanoma with positively no side effects, but we are talking about two different therapies here.

How old is Tikka?

Given that Tikka has numerous other involvements, I would definitely ask if any type of excisional biopsy would add much information. One of my big cat mistakes was allowing a biopsy of SCC in the mouth of a cat years ago. The prognosis was poor and the cat suffered from the biopsy.

There are specialists who do only palliative care in the Los Angeles area. The answer to this may depend on where you live, but my cat vet also does home palliative care.

These are excellent questions for your oncologist.

Hi. I am sorry for what is going on with your cat.
I am not a vet.
posting bloodwork would be interesting and could be helpful.
What is she on for the SCL? What other medications is she on?
I would talk honestly and openly with your oncologist.
I wouldn’t want to do surgery on my cat if she was in the same situation.
They may not be able to recommend a chemo protocol without knowing what the cancer is, but the oncologist may be able to read the results of the fine needle aspirate better than your regular vet. But they will want to biopsy.
I understand you’re not wanting to biopsy and, like I said, if she was mine, I wouldn’t.
The oncologist should be able to give you a better idea of what your options are.

I have posted a link below that might get to technical but it is interesting on cytology etc.

So sorry to hear about your previous experiences, that’s so scary to lose someone that quickly.

Yes, Tikka is still on the chlorambucil on a pulsed dosage (every two weeks). Good memory! That did worry our local vet a bit, if the tumor is aggressive enough to grow despite the chlorambucil.
Tikka is 17 now, but she is still plenty active.

We are at the vet now, and both the oncologist and internist seem to think the x-ray may not show signs of metastasis after all. Apparently what our local vet saw may have been calcification instead. We’re having them sent to a radiologist for another opinion, but if that’s the case then hopefully palliative care is still far away…

Like Fiona’s mom mentioned, Tikka takes chlorambucil for her IBD/SCL. She also takes prednisolone 2.5mg daily, cerenia 8mg as needed (but giving daily these days). For UTI prevention, she takes 1/8 tsp d mannose every day, and for her joints she’s taking cosequin daily.


So far they have not recommended a biopsy so fortunately we have not needed to make a decision on that. However, they are saying that we may have discovered it early enough that surgery may be an option, so that’s another decision we’ll need to think about…

Here is the link to the spreadsheet with the blood results:

I do hope that it is calcification and not mets. That would be some good news, at least!
