Top Ten Boxer Bumps

Boxers Grow Lumps and Cancer Better Than Any Other Breed of Dog*

But if you live with a Boxer, you probably already know this! Did you know Boxers used to have a predicted lifespan of 4-6 years? The breed was bogged down with genetic predisposition to cancer, and they passed on an inherited heart condition that shortened their lives.

The breeders got together and agreed to selectively breed healthy dogs so as not to pass on the traits. Now, Boxers can expect to live 8-10 years, sometimes as much as 12-14 years, or longer.

Still, if you see a new growth or lump on your Boxer, have your vet check it urgently.  Here is a rundown of the good, the bad, and the ugly…

Boxer Bumps I’ve Diagnosed:
1. Mast Cell Tumor, the chameleon of lumps, can look like any other lump! (bad, but potentially curable if caught early)
2. Lipoma, fatty lump, this is what you hope every lump turns out to be. (good)
3. Adenoma, a cauliflower-looking skin tumor.(good)
4. Hair follicle tumor, or cyst. Also recently named Subcutaneous Keratinizing Trichoepithelioma. The pathologists love to classify and reclassify.(good)
5. Histiocytoma. Raised, cherry-red lump. Your vet can do a simple test to diagnose this little number. Quite curable!(good)

6. Hemangiosarcoma. A tumor of blood vessel lining cells. No one yet knows if early detection would increase survival from this devastating tumor. Now that ultrasound and computed tomography (CT) are becoming more available for animal patients, perhaps these tumors will be found to be more survivable.(very bad)
7. Lymphoma, inside and out. Treatable.(bad)
8. Acanthamatous Epulis. Lumps on the gums in the mouth. Your vet can diagnose gingival hyperplasia (overgrowth) from these growths that can be invasive and cancerous.(bad, but potentially curable)
9. Osteosarcoma. Bone cancer. If a leg is suddenly super painful, and especially if there is a hard lump at the pain spot, do not delay. Even if you don’t want to hear the bad news, you also don’t want your Boxer to be in pain. Go to the vet and get answers and at the very least, painkillers.(bad)
10. Sometimes a lump is just a lump! Bee sting, skin infection, hair follicle cyst, allergic reaction (boxers get hives.)

Good Luck, Go to Your Vet, Don’t be Afraid, they’re there to help you!

**As of May, 2010, Golden Retrievers have been declared the most likely breed of dog to grow cancer.  Good news for Boxers?  Only if they don’t have a Golden Retriever friend at home!

    Thank you so much!!!!!
    You have already told me in less than 10 minutes of reading more than my vet has told me in 4 months!
    Can you tell me just how simple the test for Histiocytoma is?
    Also, how is it determined if it is a Hair follicle tumor? There is no puss involved with this bump.

      Dear Brien,
      Did you read the histiocytoma post? The test for histiocytoma is very simple. These bumps do tend to bleed a bit, so have a gauze pad ready. The histiocytes are also technically tricky to identify via microscopy. A talented veterinarian can identify histiocytes, usually without sending to sample out to the laboratory.
      A hair follicle tumor is usually on the list if the aspirate cytology does not show other tumors, like histiocytomas, mast cells, round cell tumors, purulent exudate (pus). Although, sometimes a hair follicle tumor can become infected and ooze pus. Dermatology is a tricky part of veterinary medicine. I determine hair follicle tumor patly by looks, partly by the aspirate cytology, and partly by performing the surgery, and getting the official results from the pathologist.

        I have just read your comments about histiocytomas. My 11 and a half years old male boxer was diagnosed with a histiocytoma on the outside of his ear 3 months ago. He was given antibiotic gel as he had scratched it and I was advised to keep an eye on it and that it should go away, but it could possibly get worse before it gets better. It has grown in size and now I am worried. Would you advise another visit to the vets?
        Many thanks for your help,
        Kind regards,

          My advice is to have it rechecked if it has not gone away on its own in 2 months. Every few years, I must surgically remove one.

    How old is too old for surgery? My pup is almost 11 and I saw a few lumps when I saw him last (my parents take him while I’m in school). I’m going to take him into the vet sometime next week but my mom said surgery is a no no because he had seizures for a few weeks after the last surgery he had a few years ago.

    Thank you for your time

      Dear Chris,
      There is no set age when a dog is “too old” for surgery. It is a complex decision. Your parents and your veterinarian will work together to decide if the risks of surgery outweigh the benefits of surgery. Sometimes a dog is so miserable without the surgery that the risks are worth it because they may be on pain or suffering without. In that case you take a chance and hope surgery can make their life better. Of course, unfortunately, if the risks are high and the surgery is very expensive, you also have to weigh the family budget into the decision. We wish it weren’t that way, but sometimes surgeries can be so expensive and the outcome so uncertain that it may be better to leave a dog as they are and not start up with surgery.

      Good luck! Keep the lines of communication open with your family.

    My 11 year old female boxer has a hard half tennis ball size lump on the underside of the front leg between that elbow and shoulder. It feels as though it is attached to the muscle. She is in no pain and acting perfectly normal. The vet said it is not attached to the bone and he doesn’t think it is a lymph node b/c the others are not inflamed. He did a biopsy instead of a fine needle aspiration and the wait for the results are making me crazy!!!! All he said to me after the biopsy is it wasn’t black, but red and meaty. He hoped it was just a fibrous tumor. I find very little information on fibrous tumors, when I search the dreaded “cancer” word is all that I find info on. Do you any information on fibrous tumors in boxers?

      Dear Sara,
      I’m sorry to hear your Boxer dog has a tumor. Unfortunately, Boxers are known to grow tumors more easily than most other breeds. If you live in the Tampa Bay area, feel free to make an appointment with me 877-378-7854. If you do not, then your question is one for textbooks or for your veterinarian to answer. Of course, I took many, many hours of education of fibrous tumors in dogs and Boxers. I cannot begin to tell you anything meaningful or helpful in an internet comment. A quick google search brings up 100’s of interesting articles about fibrous tumors in Boxers, but they are not going to help you decide what to do for your dog. Or even how to care for her or him or what to expect. Those really are valid questions for your veterinarian who knows your dog.

      For my clients, this is a discussion I provide time for. Of course, you must pay the veterinarian for their time and expertise. But I can tell you need answers beyond a few vague words. If you cannot schedule a consult with me, perhaps you can inquire of your trusted veterinarian how much they would charge to give you 30-minute or 60-minute consultation about your dog’s future and your options.

      Good Luck!

      Dear Tiffany,
      For sure you should see your veterinarian for medical diagnosis and advice.
