We had an appointment with the vet school Monday to check the lump in his rectum, plus another he had on his paw and another on the back of his neck.
Good news, the paw and neck lumps were benign. The one on his neck was a cyst that drained completely when they went to aspirate it.
Bad news, the vet was pretty sure the lump in his rectum was a recurrence of the anal gland cancer, so they did X-Rays and an abdominal ultrasound. Good news there was that the X-Ray of his lungs was totally clear. Bad news was that they found a couple of enlarged lymph nodes on the ultrasound. Worst news, they also found a large mass on his spleen.
Yesterday, he underwent surgery to remove his spleen, and while they were in there they also removed the lymph nodes and the rectal mass. I was so sure I didn't want to pursue additional surgery, but the alternative was that the mass could rupture unexpectedly and that would obviously be very painful and fatal. I am out of town this weekend and my mom is watching him, she said she couldn't bear to be worried all weekend that something could happen while I was away, so we did the surgery to buy a bit more time. Apparently the mass ruptured as soon as they took it out, so it was much needed.
Now, we just wait to see what the results of the spleen mass are. If it is cancerous, he could have a few months left before it pops up somewhere else. If it is benign, then he could have much longer as all of the visible cancer will have now been removed and we should have a bit before the anal gland cancer pops up somewhere else (and it's much slower moving). The vet said it was 50/50 if it was cancerous or benign. I'm hoping that the odds of a single dog having three separate types of cancer is low, but what do I know?
I get to bring him home tonight, he's been doing well and has been so incredibly brave. I'm grateful to the surgical vet as well as the intern we've been working with, they've been absolutely amazing.
