Don’t Wait to Aspirate: JD Grows New Bumps
Nobody likes to find new bumps on their dog, particularly since one was a mast cell tumor already.
Since having his bumps aspirated and a mast cell tumor removed last October, JD decided to grow a couple of new ones. Again, they were quite small and there was the possibility that he might have run into a branch and that’s how he got them.
We waited a couple of weeks to see if they would go away. But they did not.

Taking a closer look
It was time to have a closer look at them.
We set up an appointment to have them checked, measured, mapped and aspirated. Waiting to find out what the bumps are is always unnerving. Just because he had one mast cell tumor it didn’t mean these would be tumors also but it didn’t mean they wouldn’t.
When the vet examined them, one of them felt nice and soft but the other one, on his hip, was harder and felt suspicious.
Don’t wait to aspirate
They got both aspirated.
The stuff on the slides looked the same from both. Liquid-like and shiny, like a squirt of oil. That was a good sign because that’s what stuff from lipomas, benign fatty tumors, looks like. But it still needed to be checked properly under a microscope.
The vet said she has to let them dry a bit and then she’ll look at them. Depending on what she sees she will either send it off to the lab or be done with it. She was going to call us that day.
Waiting for the results
We got no phone call that day, or the next, or the next.
At first, we figured they were just busy. But then thoughts start creeping into the brain. When Cookie had her ultrasound done, the vet didn’t call because it looked suspicious. She sent it off and figured she’d wait until she hears back from them so she has something conclusive to tell us.
Sounds good in theory but when you’re not getting any news, you figure it’s bad news anyway. As it turned out in Cookie’s case, it wasn’t, but could have been.
When we weren’t hearing back regarding JD’s cytology, we figured something looked suspicious too.
On day four we finally got the phone call. The vet was apologizing profusely–she’s actually been calling since day one but copied the phone number wrong and was calling who-knows-where. After nobody was picking up the phone for three days, she decided to double-check the number. And that’s where the gremlin was.
The good news
I think she felt even more badly when she realized what the delay made us think. However, she only had good news for us.
There was nothing suspicious on those slides at all.
Just fat cells and a few epithelial cells. Everything looked so good they didn’t even send it out. There were no doubts that both of those bumps are lipomas.
JD is in a clear this time.
We will continue to keep an eye on these and on a lookout for any new ones. But for now, there is nothing to worry about.
Knowing is always better than not knowing
There is nothing to worry about and we KNOW that.
Why would owners, or even vets, be reluctant to do fine needle aspirate beats me. The whole procedure is quick, easy, and painless. It cost less than $40 Canadian. You do this and then you know. You either get to relax or take action.
Why not just aspirate?
There is not a single reason against doing that. And there are a number of reasons why do it. When you find a bump on your dog, just do it.
Don’t wait, aspirate.
