My cat has a bleeding lump with black stuff. Should I pull it out?

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! I understand your concern! It is hard to tell exactly what a skin mass is by just looking at it. You need either to biopsy or aspirate it for a definitive diagnosis. With that being said the bump on Kajoor appears to resemble a sebaceous adenoma. Which is more common in dogs. I would consider removing to for biopsy. If it is <8mm and Kajoor is a calm cat your Vet could consider removing it with a local block of lidcaine and a punch biopsy device. I hope this helps and I wish Kajoor the best!

Thank you for providing a picture of the bump on your cat, it's very helpful! It could simply be a benign growth, as it looks like it could be one in your picture, but unfortunately I cannot make the determination for sure without seeing him in person and doing tests on it. It is a bit concerning that it has grown up to 4x in size and is bleeding. It could be bleeding because he is scratching at it, but again I don't know unless I see him in person. Due to the fact it has grown in size and is bleeding for some reason, then yes I do think this is concerning enough to see the vet. It would be good to get the exact diagnosis of the bump; in addition, your cat is 10, which means he's a senior cat, and there is always a risk that any bump in a senior cat could be malignant. I'd give your vet a call to make an appointment. I hope this helps!

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!

This lump needs to be checked and analysed as there are many conditions and types of tumors that could look like that. take Blacky 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. That type of behavior of coming and going is typical of a mast cell tumor though of course that is not the only possibility. Another possibility is a recurring infection. There is no way of knowing what it is just based on its appearance.
