Well, it's liver cancer. Normally, surgery could give him a few more years, but that's for one tumor. He has two, on two different lobes, and the rest of the liver is abnormal so the cancer may be diffuse. That means he's not a good candidate for surgery. At the recommendation of both the oncologist and our vet, we're going to start him on a liver supplement and make however long he has as happy and comfortable as possible. Fortunately, he's relatively healthy and isn't having symptoms yet. This was caught during routine annual exam blood work which led to the ultrasound and cytology that diagnosed the cancer. The cancer he has is a slow growing cancer, so I'm hoping he has at least one more good year left.
