My cat has this black, soft, lumpy scab on her chin that grew, fell or got scratched off and has grown again. What is it and what should I do about it? Pet's info: Cat | Mixed Breed | Female | spayed | 14 years and 2 months old | 6.6 lbs

This lump/growth should be ideally examined by your veterinarian to have a definitive diagnosis. Your vet will examine it and possibly perform with an FNA (fine needle aspiration) or a biopsy. Differentials would include skin cyst, infections or benign or malignant type of tumors. Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

This could be a growth and in a cat Laurence's age, this could be malignant. It may be able to be removed, but I can't say it for certain without seeing him in person. 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 his vet a call in the morning to make him an appointment. I hope this helps!

Thanks for using Petco Pet Education Center, formerly Petcoach! These look like tumors of some kind. I cannot tell you what they are just based on pictures though possibilities include mast cell tumors, melanomas, among others. I recommend that you have him evaluated by your veterinarian for further assessment which includes a test called fine needle aspirate which will likely help reach a diagnosis. In some cases a biopsy is needed. Treatment will be dependent on findings. Good luck!
