My 10-year-old outdoor cat has a growing ear cut. Is it cancer?

Yes, I would strongly suspect squamous cell carcinoma in an older white colored cat. The microsporum was likely an incidental finding. If this was my cat I would definitely remove the pinna and send it to a lab for histopathology. If it is SCC, the surgery should be curative. Here is a link to a good article about this problem: ( https://veterinarypartner.vin.com/default.aspx?pid=19239&id=4952685 ) Hope this helps. Best wishes.

It is difficult to diagnose without actually seeing the lesion but it could be an infection or possibly a squamous cell carcinoma which is more common in white cats. If your vet is not able to diagnose then you should find another vet in your area that can examine your cat.

Ouch! That unfortunately should be checked out by a vet in person, especially if it's growing in size and looking more inflamed than usual, as this could indicate something such as an infection or growth that requires treatment. Typically, a vet will be able to take a sample of the area to determine the exact cells present and what treatment is needed. Until you can get to the vet, placing an Elizabethan (cone) collar on Sebastian may help keep him from rubbing or pawing at it to help it heal. Keeping the area clean and dry may also help. If you're having trouble affording veterinary care, these resources may also help so that you can get Sebastian in to see a vet: https://www.humanesociety.org/resources/are-you-having-trouble-affording-your-pet , https://www.dogheirs.com/resources-affordable-veterinary-care/

Your suspicions are right. This is a skin mass unfortunately. Due to the color, I would recommend having Nanni seen by your vet and the mass sampled to see if this is cancerous or benign (non-cancerous). Hopefully it is not cancerous and we can just monitor it. But if it does end up being cancerous (after viewing the cells that make up the mass microscopically), then removal of the mass can be discussed with your vet. I wish you all the best moving forward with Nanni. Take care!

Poor Moto! I am concerned that could be a type of cancer called squamous cell carcinoma. The only way to know for sure is to biopsy the lesion. He should have a work-up with blood-work and x-rays and also discuss aspirating and/or biopsying his lesions/masses. You should call your vet and schedule an examination.

Complete surgical removal of the mass and the remnant of ear tissue is probably the best and most effective way to treat it. I would recommend to discuss it with your vet as the best treatment option should consider her full clinical status (basically other problems if present).

A picture may be helpful. If its not bleeding or bothering him, it is not an emergency. However, I would recommend that you get it checked out, as it may be a tumor. Skin tumors can be benign or malignant, and surgery can many times be curative. Get him in to the vet when you can! thanks for asking Petco Pet Education Center, formerly Petcoach!
