What is Thyroid Cancer (Adenocarcinoma)?

Thyroid cancer is most often discovered when a mass on the neck is noticed by a pet owner. Sometimes a pet can be asymptomatic for problems but has a cancerous tumor growing on the thyroid which is seen once it reaches a fairly large size. Thyroid tumors can be either benign (adenomas) or malignant (carcinomas). Adenomas are typically nodular shaped and filled with fluid while carcinomas are the tumors we see that bulge from the throat area and have a necrotizing effect on the tissues within them. Most thyroid gland tumors do not affect thyroid hormone levels. Documentation shows that large breed dogs of middle-age to an older age are the most often seen patients in the veterinary field.

An adenocarcinoma is a carcinoma (neoplasia beginning in the epithelial cells) that started in glandular tissue. A thyroid gland tumor can be either benign or malignant with the adenocarcinoma being of a malignant form. Metastasis is common and the tumor is often a very large palpable mass present on the throat area.

Symptoms of Thyroid Cancer (Adenocarcinoma) in Dogs

You may notice that your dog has a mass on the neck. There have been cases of thyroid cancer growing on the neck in an area away from the thyroid, and in the chest or  under the tongue. The mass can be either movable or fixed and can sometimes cause the face to swell.

  • Your pet may cough
  • Your dog could have difficulty swallowing
  • He may gag, especially when eating
  • He might have trouble breathing if the tumor is obstructing the throat
  • Often there can be a change in bark sound
  • Your pet could lose his appetite and experience weight loss

It is rare for a tumor to affect the hormonal function of the thyroid. However, it can happen and in those cases you will see additional symptoms. With hypothyroidism, your pet could be lethargic, have some hair loss, and suffer from exercise intolerance. In the case of hyperthyroidism, dogs can have signs including heart trouble (rapid rate and abnormal rhythm), increased hunger and thirst, and muscle tremors.

Types

Thyroid tumors are classified as non-functional (not affecting the thyroid function) and functional (meaning they produce excess hormones that could lead to hypothyroidism or hyperthyroidism).

Causes of Thyroid Cancer (Adenocarcinoma) in Dogs

As with human cancers, the cause is not always easily discernable. In the case of thyroid cancer age can be a factor (most dogs are middle-aged to older), and there is an over representation of the Siberian Husky, Golden Retriever, Beagle, and Boxer breeds in studies of this adenocarcinoma.

Diagnosis of Thyroid Cancer (Adenocarcinoma) in Dogs

During the physical examination of your pet, the veterinarian will assess the mass (fixed or moveable) and will check the lymph nodes in the region for swelling. While the physical is taking place, it is an opportune time to discuss your pet’s symptoms and the concerns that you have that led you to bring your pet to the clinic. The eating habits, behavioral changes, and signs of discomfort are important things to note and discuss with the veterinary team.

Testing may begin with a complete blood count, serum biochemistry, coagulation parameter, and urinalysis, as well as a thyroid panel to determine the function. Additional testing will include the following.

  • Thoracic (chest) x-ray to verify if metastasis has taken place
  • Ultrasound and/or computed tomography (CT) scan are the best tools to use to see how deep the tumor is and how large it has grown, and to assess the organs of the body
  • A biopsy may be done, but often it is done at time of surgery if this choice is viable

Treatment of Thyroid Cancer (Adenocarcinoma) in Dogs

There are many factors that will determine the method of therapy. The invasiveness of the mass, the size of the tumor, whether it has metastasized, and the presence of hyperthyroidism or hypothyroidism all become important points for the veterinarian to consider. Surgery to completely remove the tumor, and additional therapy to assure all signs of the cancer are removed are the goals for treatment. Because many tumors are very large upon diagnosis and have quite possibly metastasized, surgery could be accompanied by measures that may cause discomfort for your pet. Additionally, not all tumors can be removed, depending on their location and how deep they have grown. Due to these factors, surgery may be one step of the treatment with chemotherapy, radiation, and possibly radioactive iodine or cobalt irradiation necessary as additional steps to eradicating the cancer. Your veterinarian is the best person to give you guidance and advice regarding the adenocarcinoma; she can lead you toward the best decision for your pet while keeping his quality of life in the forefront.

Recovery of Thyroid Cancer (Adenocarcinoma) in Dogs

Depending on the course of treatment, your dog could quite possibly have many follow-up visits to the clinic for additional sessions of chemotherapy or radiation after surgery. If your pet did have surgery, he will need quiet care at home once he is released from the hospital. He will have an incision that will have to be monitored by you to ensure that there is no redness, oozing or infection. Provide a soft bed for his recuperation and make sure that your dog has plenty of water and fresh food. He may have pain medication so be sure to administer this according to your veterinarian’s instructions. Call the clinic immediately if you have concerns or questions about your canine companion’s recovery.

Hello my name is Jennifer Miller
I have a six-year-old golden retriever named Wendell. He was recently diagnosed with bilateral thyroid tumors

We saw specialist on Saturday who is recommending surgery. He’s tumors on the small side and they are still move which I’m told is a good thing.

To be honest I am terrified of having the surgery. I’m concerned about his quality-of-life. Also the long stay in the hospital they told me it could be anywhere from 4 to 10 days for him to regulate himself.

Wendell already suffered from anxiety he’s a very nervous puppy

He currently is a grain free diet and he streets are 99% fruits and vegetables he comes running for asparagus and green beans

I’m looking for any advice or information to help me make a better decision

I would really like to make a holistic approach with us but I also don’t want to miss out on having the surgery while the tumors are still small.

my question are.
How fast do these tumors grow?
How long can he live a normal life with and with out surgery. Wendell's surgery is going to be almost $9000.00
Have you heard about the Budwig diet?


Thanks so much for your time and consideration

Dogs are usually affected by malignant thyroid tumours and surgical removal is the treatment of choice alongside chemotherapy or radiotherapy; the rate of growth and possible spread may be fast which is dependent on the specific type of thyroid tumour and other factors. Life expectancy in a favourable case may be up to three years (but normally less) but each case is different and you should discuss the specific case and size of the tumours with your Specialist who would be able to give you a better indication based on their assessment of Wendell. As far as the Budwig diet, I will refer you to Cancer Research UK and their page on the Budwig diet in humans for you to make a decision.

My Dog was recently diagnosed with a Thyroid tumor. A needle biopsy indicated it was a carcinoma. She went into surgery and it was successfully removed. While in surgery, another small spot was discovered slightly below the primary mass, which was also removed. The tumors had not metastasized and they were able to be removed completely. My question is treatments are we to expect from here?

It really depends on Chloe and how she is feeling, thyroid supplementation may be required if Chloe has low thyroid hormonal levels and calcium levels should be monitored if the parathyroid gland was also removed. If there is no sign of metastasis and the mass was reasonably small (and removed with good extraction technique), chemotherapy and radiotherapy may not be required; your Veterinarian will be able to guide you better about Chloe’s case.

None apart from lump

My 10 year old collie/lab cross has just been diagnosed with a thyroid tumour. It is attached so I feel surgery may be risky & don't want to put him through unnecessary trauma as he is so well at the moment,my gut feeling is to not do anything & to have him as fit & well as he can be until he isn't, but then I feel bad for doing nothing! With no other symptoms apart from the lump, thyroid & calcium levels normal can you give an idea of how long he could stay fit for? I know you haven't got a crystal ball & cannot say for definite but if you could give me an estimated ball park figure I would be so grateful!.

Thank you for your email. There isn't anything wrong with deciding to keep Robbie comfortable as long as possible rather than have him undergo a high risk surgery. I'm not sure if your veterinarian thinks the surgery is a high risk one, or if you do, but it might be worth talking to your veterinarian to see what the expected recovery might be and if it would significantly help Robbie's condition. Without seeing him, or knowing what type of tumor it is, I can't comment on what his prognosis is, but your veterinarian will be able to talk to you more about that as well. I hope that everything goes well for him.

Whilst I understand your concerns about Wendell, it would be in his best interest to have the surgery and to recover as an inpatient under your Veterinarian’s guidance; I know it can be stressful but we have anxious dogs being admitted to clinics all the time, it is a case of needs must and what is best overall for the patient.

Thyroid tumours are not typically painful, but large masses can cause issues with the trachea or larynx which may cause other problems. It is important for you to follow any instructions given to you by your Veterinarian and to have regular checkups. Regards Dr Callum Turner DVM

Has Symptoms

Coughing, difficulty breathing

This is the third mass that my beagle has had in the last two years. The first two were taken out by surgery. This time we chose to not do surgery as the recovery for her was too much for her the second time. She has a cough after drinking water, eating, and when she awakes. She sleeps a lot and snores very loudly and I believe that it is because of the tumor. I am not sure what to look for when it would be the right time to let her go. She has started to have trouble breathing while just walking around the house and she has been panting a lot more. Can you give me more info on what to look for when it is would be time to let her go?

Dr. Callum Turner, DVM

It is never an easy question to answer, an enlarged thyroid may cause extra luminal pressure on the trachea or on the larynx causing coughing, panting, signs of pain among other symptoms; you should have Peanut checked over by your Veterinarian to see what symptomatic and supportive care options are available for Peanut during this time. The decision to go through with another surgery is down to you, but I understand your reluctance after the last surgery; generally when looking at ‘the time’, it is difficult to say but I generally look for behavioural changes and a lower standard of welfare due to the condition.

My 12 year old dog has thyroid cancer. The tumor is huge and surgery was not a viable solution. Anyway, I walk/run daily with my three dogs, approximately 4-5 miles. The last two weeks she has become slower. The last two days she has had a limp- left front leg. No apparent injury. Wondering if the tumor could be the problem? Pressure on a nerve?

There could be many things going on here including extra luminal pressure on the trachea, other injuries, age, among other causes; I would give Sassy some rest over the next few days to see if there is any improvement in her movement, if not you should take her for an examination by your Veterinarian.

Has Symptoms

Candida
history of skin problems
makes noise when swallows
swollen throat below collar,
Muscle Tremors
Overheats easily

Hi, my Border Collie Lab mix has had all over his body dry skin, itching, candida yeast blooms, smelling bad, etc. The Vet told me he needed his thyroid checked, and I did not do this because I was sure it was candida. I have instead switched to raw food,and giving wormwood, black walnut, garlic and a mushroom immunity complex and he looks and acts so much younger and the skin issues have disappeared. He is as active as a puppy. But today I felt that the area below his collar and above his chest on the front of the throat seems large, and he seems to make a little noise when he swallows sometimes (not when eating, just sitting). He's overheats really easily in warmer weather and pants a lot. I will take him in to get it looked at, but is the Thyroid connected to yeast in dogs? Would he have enlarged thyroid if there were hypothyroidism or would this be a tumor? I thought maybe it was just swollen from something stuck in his esophagus, which we would have to remove, but these articles are now scaring me.

Thank you for your email. Dogs tend to get low thyroid, not high thyroid, and they aren't prone to thyroid tumors, although they do occur. Thyroid disease can make the skin unhealthy and allow for yeast to overgrow on the skin. Your veterinarian will be able to evaluate Wiley, assess the area that you are feeling on his throat, and do any testing that might be required to find out what is going on with him. I hope that things are easily resolved for him.

Hello i cut my dog hair and after a while her hair is growing but still one place without hair and i cannot know why its happen and i'm afraid because i have a baby in the house is it possible it could be thyroid?

It can take a little longer for hair to grow back in some dogs, whether they are older, or it is seasonal, or they have an endocrine disorder. I wouldn't assume a thyroid problem just based on that information, and it would probably be best to have her seen by a veterinarian, as they can look at her, determine what might be going on and if any treatment is needed.
