What is Tumor of the Throat?
A tumor in the throat in dogs is an uncommon occurrence. However, it does happen and can have serious consequences for the health of your pet. A growth in the throat area can be benign, but may also be malignant. In some instances, a tumor in the throat will arise because of a malignancy elsewhere in the body. Surgery is usually the standard method of removal, along with treatment for the underlying cause if needed.
The throat can be the location of many types of tumors in canines, with two examples being tonsillar and tracheal. Often masses of aggressive nature, malignancy is common, and detection at an early stage will offer the best prognosis.

Types
The list for types of tumors of the throat in dogs is very extensive. Some of the growths that can be diagnosed are found below.
- Laryngeal tumor
- These are found on the wall of the larynx and can cause a respiratory obstruction
- Laryngeal oncocytomas occur most often with young dogs, but are fortunately minimally invasive
- Chondrosarcomas of the larynx are mostly of the malignant sort and develop in connective tissue of the larynx
- Squamous cell carcinoma of the larynx can form in the upper, middle or lower area
- Tracheal tumor
- Chondrosarcomas of the trachea often spread to regional lymph nodes
- Squamous cell carcinoma of the trachea will invade other regions of the body like the esophagus, thymus and lymph nodes of the chest
- Tonsillar tumor
- These tumors are highly metastatic and will metastasize early in their development to organs and regional lymph nodes
- Squamous cell carcinoma tumors can invade the bone and are highly aggressive
- Esophageal tumor
- Squamous cell carcinoma of the esophagus is often found in German Shepherds, Basset Hounds, collies, Keeshonds, and Schnauzers
- Studies show an infestation of parasitic worms called spirocerca lupi can cause osteosarcoma of the esophagus
- Thyroid tumor
- This type of mass can appear in the esophageal area
- They are usually large and invasive
- Golden Retrievers, Labrador Retrievers, Boxers and Beagles are breed predisposed
- Mast cell tumor
- The average age for dogs with this growth are nine years of age
- Boxers, Boston Terriers, Beagles, Bulldogs, and Schnauzers are presented often in studies
- The location is found all over the body, but in the throat, it is usually on the larynx
It should be noted that the closer a tumor is to the lymph nodes of the throat, the more chance there is that it will metastasize.
Causes of Tumor of the Throat in Dogs
The definitive cause for tumors of the benign or malignant type is an ongoing study for scientists and researchers; a cure is hopefully within reach. Reasons that your canine companion may have developed a mass in the throat are listed below.
- Genetics
- Infection
- Invasion of cancerous cells from elsewhere in the body
- Cell malformation
- Damaged cells being replaced by cancerous cells
- Age
- Environmental pollutants
- Chronic inflammation
Diagnosis of Tumor of the Throat in Dogs
The variety of tumors that can present themselves in the throat of our beloved canines is extensive. Because of this fact, the diagnosis procedure could be of an extensive nature as well.
Learning that your pet has a tumor can be a distressing time. Remember to allow your veterinarian to use her expertise in the diagnostic process; her goal is to provide the utmost care to your canine family member. Methods that will be considered as part of the evaluation and investigation could include the following.
- A complete blood count, chemical profile, and urinalysis are usual starting points
- Radiographs of the trachea or esophagus could be done if the tumor is suspected to be located there
- A chest and neck radiograph may be done
- Fine needle aspirate cytology could be needed to check the lymph nodes for cancer cells
- An endoscopy or bronchoscopy may be done, depending on where the tumor is, and whether the procedure would be risky
- A biopsy might determine if cell death or inflammation are present
- A thyroid function test (blood test T4) will measure the level of thyroid hormones in the blood
- Nuclear scintigraphy may be suggested (radioactive material is injected to locate cancer, and it’s spread)
- Computed tomography (CT) scan or magnetic resonance imaging (MRI) can evaluate the invasion of cancer into bone, lymph nodes, and lungs, or the nasal, oral and ocular areas
Many of these diagnostic tests will require your dog to be sedated or put under general anesthesia. He will be carefully monitored throughout.
Treatment of Tumor of the Throat in Dogs
Your veterinarian will discuss which method of treatment will offer the best prognosis for your family pet. The options will always depend on the health condition of your pet when the tumor is discovered, his age, how comfortable he is in regards to airway restriction, and his general sense of well-being. It should be noted here that treatment is not always an option. If a tumor is malignant and cancer has spread aggressively, the best solution for the sake of your dog may be palliative care or euthanasia.
In the case of a tumor that is benign, or that may be malignant but can be completely excised (for example if it is easily reached by a surgeon), surgery will be the choice of action. There are many types of surgical intervention that your veterinary team will discuss with you. For example, a tumor in the larynx may involve a laryngectomy, and a tracheal tumor could require a removal and resectioning of part of the trachea. In most surgical cases, chemotherapy and radiation will follow.
Thyroid tumors can present a different scenario because medical control of the thyroidism (whether hypo or hyper) needs to be also managed. Typically, most thyroid tumors are found to be malignant. External beam radiation is one method used to destroy thyroid tumors.

Recovery of Tumor of the Throat in Dogs
As the owner of a dog who has had a throat tumor, you should be aware that recurrence is possible, even after surgery, chemotherapy and radiation. More than that, the knowledge that the longevity of your much-loved dog’s life may not be extended that much further even with treatment, should be a consideration. Do not hesitate to ask your veterinarian for an honest, heart to heart recommendation of what is best for your pet.
If you are in the fortunate circumstance that a full recovery is expected, you should be prepared to spend the time needed after the surgery to nurse your pet back to health. He will benefit greatly from a quiet area in which to rest and sleep. Your veterinary team will provide information for the home care such as special dietary requirements necessary after throat surgery, and instruction on the administration of pain relief and antibiotics as prescribed. Follow-up radiographs may be scheduled at 2 to 4-month intervals for quite some time as complete excision of the tumor is often impossible, and the chance of recurrence is always present.

My pet has the following symptoms:
Fever
Lethargy
Lump
Hi there, my dog has a lump on her throat/neck which is accompanied by high fever (104.4), low appetite, bloodshot eyes, and extreme lethargy. The vet has aspirated it, but the lab is closed until Monday (2 more days). Vet is treating her with 2 different antibiotics (in case it's an abscess/infection), an appetite stimulant and sub-q fluids. She seems to be getting worse, rather than better. I was just wondering if you know anything about lumps combined with fever, as a fever isn't listed in the symptom list above. Thank you!

It really depends on which structure the swelling or growth is originating from, there are many structures and glands in the throat which may be possibly affected; thyroid, parathyroid, lymph nodes, salivary glands among structures may cause swelling or enlargement. Fever may be related to infection, inflammation or allergies (no so much allergies); for now keep an eye out and see what the histopathology report comes back with. Regards Dr Callum Turner DVM

My pet has the following symptoms:
Lump,Trouble W/Legs,Vomit, Wt Loss
Hello, dear doctors,
My dog, Little Bit, is a mutt, hence her name. She is a little bit of this and a little bit of that. She is 13 and the apple of my eye. She is having multiple symptoms, which may or may not have anything to do with each other. Nevertheless, I am very worried. Here are my concerns, in no particular order:
1. She is having trouble controlling her back legs. This doesn't seem to be all the time, but sometimes I have to lift her on the couch, carry her down the stairs (for fear that if I didn't, she'd go tumbling down), etc.
2. She has lost a recognizable amount of weight. I'm guessing 10 pounds - down from 145 to 135. Again, I am guessing on that. When she gave up eating any dried food, I thought she was just being picky, but now she's not interested in that food at all. Thinking it might be her 13-year-old teeth, I've been giving her wet food. This has cleared up any worries that it was her appetite because she loves that wet food.
3. She is throwing up way more than she ever used to. I'd say now it's about 3 times a week.
4. And last but not least, she has a lump in the waddle of her throat that I just found a few days ago.
Can you give me any idea of whether or not these symptoms are indicating anything or things? Is there anything I can do for her on my own? I know I should have taken her to the vet a while ago, but my finances are very tight, to say the least.
Thank you for being here and willing to answer my questions. I really appreciate you!
Warmly,
Laura

I do think that Little Bit needs a good veterinary examination. She is getting to an age where she may have arthritic issues, dental problems, or systemic diseases that need treatment to make her feel better. You'll know more about her heatlh status after an exam, and can make better decisions to keep her healthy in the longer term once you know.

Unfortunately, I"m not able to offer any solutions for Jacob, other than perhaps a second opinion with a surgeon who may be able to perform a difficult surgery. It does sound like you need to be sure that he isn't suffering. I'm sorry that that is happening to him.

My pet has the following symptoms:
Vomiting
Vim
My 9year old Rottweiler female Jessie, had a tumor removed from her mouth about 6 months ago, it was found to be malignant. She is on renal food and has always been an unenthusiastic eater. About 3 weeks ago, we had to start really coaxing her to eat. She throws up about half of the food she does eat, and has a very heavy bad breath smell. The food she throws up is not digested. I will be taking her to the vet, but what should I ask them to look at - her throat or stomach. Will they be able to pick up tumors on a normal xray as my local vet does have mri or CT machines?

There are many possible causes for vomiting or regurgitation in dogs which may or may not be related to the tumour removal; advise your Veterinarian of the surgery (if it is a different practice) and the symptoms Jessie is presenting with; your Veterinarian will make a general examination taking special care around the throat and abdomen but they may take an x-ray (which is much cheaper than a CT scan or MRI) to look for any masses (like tumours), strictures, obstructions or any other cause of vomiting or regurgitation.
