My cat has a growing neck lump. Is it thyroid? What are next steps?

The thyroid gland in cats is normally not palpable. The lump may be localized infection, inflammation, fatty tumor or a cyst just to name a few possibilities. You can monitor it for rapid change or growth. See your veterinarian for an exam if it causes discomfort or impedes motion, breathing or eating. A fine needle aspirate can be done in the clinic to collect a sample for pathology if necessary.

Thanks for using Petco Pet Education Center, formerly Petcoach! Your veterinarian may be referring to a thyroid tumor. The next step before considering surgery would be proceeding with a CT scan to check on how invasive the tumor appears to be. Then the next treatment option can be determined. A FNA can be performed at the time to determine the tumor type. If not too invasive surgery may be possible. If too invasive, and this is a thyroid carcinoma (the most common tumor in that region), radiation therapy or chemotherapy may be next best options. The prognosis with these tumors depends on the type which is why that needs to be tested. Also, it depends on how invasive it is and if it can be resected. If you think you have more information on the case that you did not describe in the question, feel free to request a consultation with me and I can continue to help. Best of luck and have a blessed day!

Hello, sorry to hear about Lucky. There are a couple of different diagnostics you may chose to pursue to tell wether or not this nodule you are feeling is accurate or not. One option would be to pursue an ultrasound of his neck to further localize the nodule. If this is unrewarding a CT scan or a thyroid scan can also be performed. Some thyroid nodules are non-functional, this means that the tumors will not produce excess thyroid hormone, however in cats most thyroid tumors are functional and they do secrete thyroid hormone. Therefore, one way to tell if this nodule you are feeling is functional is to measure his thyroid levels. If elevated, then you can almost be sure that the nodule is in his thyroid. Treatments for this include surgery if only one thyroid is affected or radiation with I-131. Medications such as methimazole and a diet deficient of iodine can help control and treat hyperthyroid cats. Hope this helps and best of luck.

If he does have a lump in his throat and has lost weight in the past year, then hyperthyroidism is a possibility. Costs will very from clinic to clinic and area to area, but as a ballpark, a blood test for thyroid function alone could be around 47 pounds, where a blood test for an old thin cat (that should cover the thyroid as well) could be around 100 pounds. There are three treatment options for hyperthyroidism: medication, surgery, or radioactive iodine. Each treatment has advantages and disadvantages, and the treatment choice depends on your cat's health, including heart and kidney function. Again, the cost will vary for each treatment, and your vet can let you know how much it could all potentially cost. There is nothing you can do for him at home to slow the disease, it's best that he's seen by a vet as soon as you can get him to one. If paying for a vet is an issue, you can see if your vet accepts payment plans, if there is a low cost clinic in your area, or you can apply for Carefree Credit online. http://www.carefreecredit.co.uk https://www.rspca.org.uk/whatwedo/vetcare http://www.easipetcare.com

Thanks for using Petco Pet Education Center, formerly Petcoach! This could be a benign or malignant growth. This is often differentiated by a test called a fine needle aspirate (FNA) which is a pain free, inexpensive and easy procedure which in most cases will help reach a diagnosis. Sometimes a biopsy is needed for a definitive diagnosis. I recommend that you have him evaluated by your veterinarian for further assessment and treatment. I am really hoping for something benign. Good luck and have a good day!

Hello, and thanks for using Petco Pet Education Center, formerly Petcoach. The only way to know for sure what this little growth is, would be to have it tested in some way. The least invasive way to test is to do cytology, where your vet can use a needle to remove a few cells from the lump and look at them under the microscope. Cytology is not always 100% diagnostic, but it is minimally invasive and often allows us to gauge a level of concern, or diagnose certain types of common masses. The way to know for sure what that lump is, would be to have it surgically removed and send the lump itself in for testing (histopathology). Histopathology nearly always gives us a diagnosis, but of course is more invasive. While Silver's age (as a young adult) makes him less prone to scary malignant growths, and growths that are very slow to change may turn out to be benign, there is no way to know for sure what the growth is without having it tested in some way. You may choose to leave it that way, but doing so without having it evaluated in some way is a little bit of a gamble. I know this isn't an absolute answer - but unfortunately the only answer can come from testing the lump. I'd say it's worth having a vet take a look at the lump for peace of mind. Hope this helps.
