Just a question for more experienced bees.

We have a dog who's 11 years old, he's a big dog so his time with us is very limited at this point.

My husband just found a big lump under his right armpit. He had bloodwork done a few months ago and it came back very healthy. Does a lump automatically mean cancer? Could it just be that he's really old and has a funny growth?

My husband is beside himself. This dog is kind of his everything and he's pretty upset. I just want to give him words of comfort. I have no idea how much time we have left with his dog.
