my sweet 12 yo JRT/beagle mix, Buster, had a right forelimb amputation last week and is recovering great, though this has been rough. This website has been a godsend to figure out how to get through it. But I found out today that the biopsy confirms he had stage 3 nerve sheath cancer, very aggressive but hasn't spread to lungs or spinal cord. Margins from surgery are minuscule, less than 1mm. So it could come back and if I do nothing may well come back in 6 months. Options include full 15-18 sessions of radiation + chemo or palliative radiation at 4 sessions + chemo. What makes this so hard is his age plus we have been dealing with his limp, plus a prior tendon release surgery that had nearly 2 months of downtime because everyone thought the issue was a torn tendon not cancer. The limp and prior surgery dominated the last 9 months - so this poor dog has been through a LOT, even before last week's amputation. The palliative radiation could give him 2.5 years, though maybe more and maybe less.  At age 12 maybe that isn't so bad. How should I be thinking about this? I'm lucky and I can afford these different options so that's not really the issue. Any advice welcome. The notion of 15-18 more vet visits with anesthesia sounds terrible to me given so much time at the vet already.
