My old dog has a perianal lump. Should I treat it at 15 years old?

Thank you for using Petco Pet Education Center, formerly Petcoach! A mass on the skin is never "normal," but it is not uncommon to see skin masses appear as patient's age. It is virtually impossible to be able to distinguish a benign versus a malignant (cancerous) growth based on appearance alone, which is why we typically rely on biopsies or fine needle aspirates for diagnosis. Fine needle aspirates are less invasive and do not require sedation/anesthesia, but only give us a small picture of the mass since we are only able to sample the cells present within the needle used. Removal of a mass with submission for histopathology (biopsy) is always preferred and recommended for masses that change in size or shape. If the mass on Bradley's leg is changing, continually infected, or is irritating/painful for him, it would be best to have the mass removed and submitted for histopathology. Even if the mass is benign, it is serving as a source of irritation/infection for him, and could potentially become malignant in the future.

Thanks for using Petco Pet Education Center, formerly Petcoach! These could be benign or malignant growths. There is no way of knowing for sure without an examination though this represents a reason to seek veterinary care. This is usually determined with an examination and a fine needle aspirate (FNA) or a biopsy. Treatment depends on the findings up to that point. I think it would be best to have her evaluated before considering euthanasia as this may be able to be treated. I recommend you have Savano evaluated by a veterinarian for further assessment and treatment. Good luck and have a good night!

Hi there! Thanks for using Petco Pet Education Center, formerly Petcoach! These look classic for perianal gland tumors. This is very common in intact dogs. The majority of these tumors are benign though a small percentage of them are malignant. I recommend you take him to your veterinarian for a test called a fine needle aspirate which can help distinguish these tumors from other more concerning tumors. If it truly is a perianal gland tumor, most of the time they resolve or greatly improved by neutering the dog as they are driven by hormones. If they are not bothering him, this may be enough. In cases when they are starting to bother the dog, you can also consider removal. Feel free to request a consult with me if wanting more information on the next steps. Good luck with your pup!

Assuming Kara is in good health otherwise - which should be established with blood work and x-rays of the chest, to ensure that the tumor hasn't metastasized - then I would recommend proceeding with surgery. Mammary tumors can be quite invasive and aggressive, but depending on the grade surgery can be curative. Just because a dog is old, it doesn't necessarily mean they can't have anesthesia - you just have to take precautions, and find a vet who is capable of taking special care. I would also get a definitive diagnosis as to what the mass is before making any decisions, There are lots of benign lumps that grow all over dogs' bodies, and just because this one is in the mammary area, it isn't necessarily an aggressive cancer. A fine needle aspiration biopsy can usually tell you what these are.

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. Based on the location, often times these tumors are benign in nature and are known as perianal adenomas though about 10% are malignant and again it could be really any other tumor type. 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! Poor Brie! I think that if the mass is getting traumatized, is bleeding or infected or if it appears painful to her then it might be time. Especially if removing it isn't an option. Otherwise, if she is eating, drinking, not in pain, the mass isn't bleeding, she interacts with the family and can control her urine and defecation then I would give her more time. I always tell owners to measure the good and bad days and when the bad days out weigh the good then it is likely time. I hope this helps and I wish you and Brie the best!
