Can't help you on this cancer don't know a thing about it. In fact I've lost one dog and one cat to cancer (lymphoma in both cases--my Aussie who was nearly 13 so I opted for palliative care only and the cat was 13 and we did the same thing with him but he had masses in his lungs which basically meant that the cancer had started elsewhere and was beyond treating, his hemoglobin count was incredibly low--it was a wonder he hadn't dropped dead from lack of oxygen already.
Good luck--do keep us posted.
