My cat has a nose bump that won't heal. Vets can't diagnose it.

There really is no way to know what the mass is without a surgical biopsy. I understand the hesitation going forward with surgery, but if it's growing you need to determine what it is, and biopsy is the best option to do so. This mass May just be inflammation or eosinophilia granuloma or it could be a cancerous mass. There are even cases of fungal disease causing nasal masses. If it is growing I would strongly recommend addressing it as soon as possible as surgery may become more difficult as it gets larger. Best of luck to Pol and I hope it is something easily treatable.

I would recommend uploading a picture of Yui's nose for us to see. You can resubmit the question and upload up to 3 pictures. If it is not resolving then the next step would be a biopsy of the lesion. That would give us a definitive answer as to what is going on.

Poor Sneakers! If she is having persistent sneezing and nasal discharge even after treatment with antibiotics, and you are also seeing a bump of some kind inside her nostril, I would be concerned that she may have a nasal tumor or foreign body of some kind in her nose. If your veterinarian does not have any suggestions for further work-up at this point, I would recommend asking for referral to a specialist for rhinoscopy (looking at the inside of the nasal cavity with a small camera), as well as other testing if needed such as a bacterial or fungal culture, biopsy of the lump, etc. to try and get a diagnosis.

First of all Purrito is one handsome little guy! The bump on his nose is fairly prominent and also appears to be a bit red/inflamed through the fur. Cats do not often get as many lumps and bumps as dogs do, so when one pops up, we take a bit more notice. Some of the common causes of bumps can include benign or malignant masses, abscesses, granulomas, or in this case, even nasal cavity infections or tumors. The only way to determine the cause of this bump is through further testing, either including a needle aspirate (a needle draws out some cells for microscopic evaluation), x-rays, or even a CT scan or MRI of the head. Even though Purrito does not seem to be bothered by this bump, I still recommend taking him to the vet for further evaluation since bumps do not often go away on their own. It's better to address these issues before they grow larger and become potentially more problematic. I hope this helps and that all goes well!

Just keep on eye on it. Seabiscuit may have gotten bitten by an insect or have a small injury. This should heal in a week or two. If it's getting bigger or becomes painful then a veterinary exam is recommended. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Seabiscuit.

Thanks for using Petco Pet Education Center, formerly Petcoach! While I agree with your veterinarian that this can be due to an infection. However, I think a fungal infection like cryptococcus seems more likely and that would only respond to anti-fungal therapy. Another possibility is cancer such as squamous cell carcinoma. I recommend you consider having him reevaluated by your veterinarian for further assessment and treatment. May be a biopsy could be done at this time since it has not improved. Good luck and have a great day!

Hi Your cat may seem fine, but even so, you should have a veterinarian check it out. There's no way to know what's going on by just seeing or feeling it. It could be an abscess, a mild trauma, or a more serious problem. The vet will preform a fine needle aspiration to take a sample for analysis and diagnosis.
