My cat has a lump under her chin. Is it a cyst or something serious?

Pets can get many types of lumps and bumps. Most of these tumors will be benign but some will be malignant and you can't tell by looks. Here is a helpful link discussing the various types of skin masses in general: https://www.petcoach.co/article/lumps-and-bumps-on-your-pet/ Since you are noticing the mass changing, I do recommend to have it checked out to be safe. The doctor may recommend to aspirate the mass to examine the cells under a microscope. That is one of the best ways to know what it is and if further action is needed. Hopefully it's nothing serious.

This growth needs to be checked and analysed as there are many conditions and types of tumors that could look like that. take him to the vet, they will perform a fine needle aspiration on the growth and send it to the lab for analysis. when the result comes, the vet will advise what needs to be done according to the diagnosis.

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 night!

Hello and thank you for contacting Petco Pet Education Center, formerly Petcoach. I suspect this is either allergic reaction or developing abscess. Please, take Sweet to your local vets for an appointment as she will likely need treatment with either antibiotics (for abscess) or anti-allergic medication (steroids or antihistamine medicine).

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.

Thanks for using Petco Pet Education Center, formerly Petcoach! This could be a benign or malignant growth. This may even be an abscess. There is no way of knowing what it is just based on its appearance. 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.
