Mammary Cancer: Mia's Story

Mia is an 8.5 years old Irish Wolfhound. When she was about 7.5, her mom found a small, pea-sized nodule on her belly. Senior dogs do get the odd lump or bump. It was small so she wasn't overly worried. Particularly because the nodule wasn't growing or changing.

"There is never a problem until there is one," our vet always says.

Your dog could have a hundred lumps that are completely benign. It does not mean that the hundred and first will be benign too.

Then, when she came into heat, Mia's little quiet bump decided to start growing. 

It multiplied in size within a few weeks. Mia's mom knew she had to take action.

On a close inspections it turned out that the original lump was not the only one there; it had company of several other small bumps.

Mia had mammary cancer.

The heat stimulated its growth.

About a half of mammary tumors are benign and remain harmless. The other half are malignant. They grow, spread locally and can spread to other parts of the body such as liver and lungs.

How does one assess which half the little bump on your dog belongs to?

Nobody can tell without a biopsy. When a little lump decides to start growing, though, the likelihood of it being malignant is high.

That is one downside of having an intact female; it increases the odds of mammary cancer dramatically.

Mia was admitted for surgery and x-rays. She is doing well.

For me, at this day and time, the question isn't whether or not to spay, merely when. As for lumps and bumps, I take them all seriously, no matter how small.

Jasmine had a bump by her nipple once.

She was about nine years old. She was spayed. But it was a bump. It was tiny, I found it because twice she gave me heck when rubbing her tummy. So we went looking for a reason and found it. Fortunately, in her case it was just an infection and cleared right up.

Whenever I find the tiniest bump on any of my dogs, I want to KNOW exactly what it is. I'm not taking any chances with bumps.

  1. Thanks for the reminder. I found a little bump in Delilah's neck area. She has had a fatty lump before, but I need to follow-up and have it checked.

    I'm glad to hear Mia is doing well, it's such a scary thing.

    1. Yes, very scary. And yes, I believe it is important to check and identify EVERY new bump, regardless of how many benign ones there may already be. It is also important to revisit any old benign bump that "wakes up" and becomes active in any way.
