My dog has a purple lump. Could it be a recurring tumor or cancer?

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. It is difficult to say for sure what these tumors are just by looking at photos. However, that being said, the light pink mass I would suspect to be benign / non-cancerous and it looks like what we call a sebaceous adenoma. The dark purple mass looks a little more suspicious for a malignant / cancerous mass. I would recommend having a veterinarian examine both to be on the safe side. The vet can insert a small needle into both masses and look at their cells under the microscope, a test called a Fine Needle Aspiration (FNA). I hope this helps guide you in the right direction! Please let me know if you have any other questions or concerns and I would be more than happy to help you further. Please remember to rate this answer as helpful or not. Thank you!

Thanks for using Petco Pet Education Center, formerly Petcoach! This could be a benign or malignant growth. There is no way of knowing what it is just based on its appearance. 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 day!

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Thanks for the pictures! Many skin masses can look the same. Red dermal masses, like this one, can be benign or malignant. Some possibilities are an inflamed sebaceous adenoma, hemangioma, histiocytoma or it could be a Mast Cell Tumor. Since it showed up quickly I would have Oscar seen by your Vet. They can decide if aspirating it (sticking it with a needle and sending the slides to the lab) or removing the mass and sending it for biopsy is best. I hope this helps and I wish you and Oscar the best!

Hi there and thank you for using pet coach to address your concern. Based on the pictures you have provided, this could be a cancerous tumor that has become infected. This should be examined by a veterinarian so that the most appropriate diagnostic and treatment recommendations can be made. It is likely he needs to have surgery to help try and resolve this. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

Hello, thank you for using Petco Pet Education Center, formerly Petcoach. Is that supposed to be the same growth in both photos? The growth if the first photo looks suspicious for a malignant tumor. The tissue around the mass is swollen and the mass itself is raised and ulcerated; both can be signs of a malignancy. I cannot tell you for sure though just by looking at a photo. The second photo looks like a benign wart. In general, any new lumps/bumps should be examined by your vet. The first photo looks worrisome and I think you should have it checked in the next few days.

This looks like a mass in the skin, it could be a reaction to infection, a benign tumour such as a skin tag or a cancerous tumour. I would get it tested by your vet to decide the bedt course of action.

Hi there and thank you for using Pet Coach to address your concern. With Stella's age, I would suspect this is likely benign and what we call a histiocytoma. To be on the safe side though, I would recommend having your veterinarian take a look at this and perform additional testing to help better determine what it could be. Your vet can insert a small needle into the mass and look at the cells under the microscope to help rule out what it could be. A histiocytoma is a benign (non cancerous) tumor that usually resolves on its own over time. I hope this helps! Please let me know if you have any other questions or concerns. I am also available via consultation if needed.
