My dog has a fast-growing mouth growth. Is it cancerous or benign?

Thanks for using Petco Pet Education Center, formerly Petcoach! This could be a benign or malignant growth. Judging by the color and the fact that it is in the mouth, it is likely a melanoma, the most common oral tumor in dogs. 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 her evaluated by your veterinarian for further assessment and treatment. I am really hoping for something benign. Good luck and have a good one!

Thanks for using Petco Pet Education Center, formerly Petcoach! This could be a benign or malignant growth. That is may be why it came back after removing it. 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 recommend you have Rufus evaluated by a veterinarian for further assessment and treatment. Good luck and have a good night!

That does look concerning. Unfortunately there is no way to tell from the appearance alone as to whether or not it cancerous. You are correct in that it may be a benign growth, it may cancer, or it may some sort of inflammatory mass from an infection of the gums either due to a dental problem or due to an embedded bit of small stick or something along those lines. Gingival hyperplasia (overactive growth of the gum tissue) is possible, however it usually appears less "mass-like." If she is still eating, active and happy, make an appointment with your vet at your convenience in the coming weeks to have it checked out. If she is not eating or otherwise seems ill, or if you are noticing that her breath is really bad, get her in as soon as you can. Your vet may recommend that a biopsy be considered. A biopsy is the only way to determine what exactly it is, how dangerous it is, and what needs to be done about it. I hope thats helpful for you!

Thanks for using Petco Pet Education Center, formerly Petcoach! It is hard to see well in this picture but this could be a benign or malignant growth. 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. There is no at home therapy for growths. I recommend that you have her evaluated by your veterinarian for further assessment and treatment. I am really hoping for something benign. There is a chance that this is benign and does not need any therapy. Good luck and have a good day!
