Dr. Nowle called on Monday with Koko's test results. The lump on her side was indeed a Mast cell tumour (her third such cancer growth). This time it graded as a 2 (scale of 1-3), a little higher than we had hoped but not at the final stage. The margins were narrow but there were margins, so this lump was totally removed.
Koko is looking great. Her stitches come out at the end of the week. The incision is healing nicely. It has not ruptured which is great, as Maggie was so excited to have her back on walks, she kept plowing her over. And that is why we went ahead with another surgery. To keep that spring in her walk for as long as we can.
