It looks like a little wart or less likely a skin cyst. These are quite harmless and go away on their own. If it grows, changes colors or starts to bother Wendyl, then you should take her to the vet to get it checked out. They can take it off easily and send it to the lab for positive identification if needed.

Hi, it is difficult to comment without having him checked over. Some lumps that appear in this area are definitely concerning and need to be checked over as soon as possible. By this I mean during regular daytime hours, but I would not leave him a week without being examined. Hope this makes sense and that the lump is nothing to be worried about.

Without seeing her in person, I can't say if this is a skin tag or something more serious. Any suspicious lumps should be examined by the vet. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of its cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. Once the cause of the lump is diagnosed, the vet can discuss treatment options if needed. Give her vet a call to make her an appointment. Best of luck.

What's this lump on my cat's skin? Is it a wart or something serious?

The pink raised mass in the picture appears to be a wart. I would not be concerned about this unless it grows or changes in color. The lump you feel could range from a cyst to a cancerous growth. I would recommend taking her to a veterinarian for an aspirate. This is where they can take cells from the mass and look at it with microscope

My cat has a growth under his chin. Is it a wart or something 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.

What is this lump on my 11-year-old cat's neck? Is it cancer?

It looks like a benign cyst to me but, of course, I cannot be 100% sure just by looking at a photo. Whenever you get a chance just take her to your vet so they can check it in person. Now that you know it is there keep an eye on it and if there are any drastic changes with it she should be examined by the vet sooner. Hope this helps. Best wishes!

My cat has a lump on his shoulder and fur loss. Should I see a vet?

It's hard to tell the size but it looks like it may be a benign wart or growth. It appears to be more on the surface of the skin which is good, and it is well defined. Cats do get malignant skin growths so it is a good idea to have your veterinarian examine it and feel underneath also. They can easily remove this if necessary and do a biopsy. I'm not overly concerned looking at the photo but it's best to be sure. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Louis.

My cat has a white skin growth, but no fur loss. What is it?

This could just be a benign growth on Mela like a wart, but without seeing her in person, I can't say for certain. The best thing to do is make an appointment with a vet to get it checked out. It's not an emergency to get her into a vet, just have her seen in the next week. Best of luck, I hope this helps!

My cat has a small neck bump that keeps coming back. What is it?

Of course a biopsy is needed for definitive diagnosis, but I suspect by the picture and what you describe that it may be a sebaceous (oil) gland cyst. They will not go completely away, but are usually pretty quiet and don’t cause problems. To be safe I would recommend having it examined by a veterinarian. Good luck to you and Willard.

What is this growing lump on my cat's face and is it serious?

This may be an abscess, a cyst or a tumor. You should have it examined by your veterinarian, as it is not possible to distinguish these by just looking at a photo. An abscess can usually be treated with antibiotics and/or be lanced, and a cyst can be evacuated. To identify a tumor, your vet may want to do a fine needle aspirate (he takes some material from the bump with a needle and then looks at it under the microscope) to determine whether the mass is concerning.
