My dog has a suspected tumor. Can we diagnose and avoid amputation?

She has most likely been diagnosed with osteosarcoma (in the forelimb probably head of the humerus) which is a primary bond tumor. Bone tumors are painful and typically amputation is recommend with follow up chemotherapy. In the event the cancer has metastasized (spread) or it is suspected the patient will not have a good quality of life with three legs, less invasion options such as radiation therapy are recommended but only as palliative measures. If you have not already discussed talking to a veterinary oncologist with your veterinarian, I would recommend doing so. They will be able to provide you with a detailed treatment plan and prognosis.

Dogs do get malignant nail bed tumors. This area does look angry and it certainly could be a malignant tumor. If you wish to be cautious you can get a second opinion from a veterinary oncologist or another veterinarian. It's difficult to get a good sample from this area so your veterinarian is correct to recommend a toe amputation. Since Hailey is young there is a chance that this is an infection also. You could try a course of antibiotics for a couple of weeks to see if it heals. If the mass continues to enlarge then I would definitely remove the toe as if it's a malignant melanoma they do spread and it could go into her lungs which is a life threatening condition.

Thank you for submitting your question regarding Abby. I am glad that she will see her veterinarian. She could have a cancerous growth, but hopefully it is a benign mass such as a cyst or other type of growth. A procedure known as a fine needle aspirate is commonly performed to diagnose a mass. The veterinarian will use a small needle to collect a sample of cells to evaluate under the microscope. Based on these results, treatment recommendations can be made. For example, if the mass appears cancerous, then surgery will be recommended. Bone cancer occurs in dogs, but is not common in the location shown in your pictures. So this is less likely. I hope this information helps!

I'm sorry to hear that Stubbs is having this problem. Without being able to see and palpate the tumor, I really can't say what surgical options might be reasonable. I can tell you that tumors on the paws and lower legs are often very challenging to completely remove without amputation, but there may be cases where this could be possible. I would suggest getting a second opinion from another veterinarian in your area, if you want to make sure that all reasonable options are being considered.

Hello, sorry to hear about Sophia. It looks like it could be a hemangioma (benign), however given her age and the appearance of the tumor, there is also a chance it could be more aggressive such as hemangiosarcoma (malignant). It would likely need to be removed and sent for biopsy to confirm/rule-out the presence of cancer. If you feel like your primary care veterinarian did not answer all of your questions, then you may indeed seek a second opinion. The appearance of this mass does warrant further diagnostics of it, especially if this mass has developed suddenly. These masses as they continue to grow, may occasionally bleed intermittently or have discharge. Hope this helps and best of luck.

It is very hard to say without knowing what exactly the vet determined the mass or growth to be. If the vet recommend amputation then I would assume the growth is some sort of cancerous growth. Most veterinarians will not recommend amputation unless a mass is very aggressive and large or unless it is a bone mass that cannot be surgically removed. I would have a more in depth conversation with your vet to discuss exactly what kind if mass your dog has and what kinds of treatments are possible. Even though your dog may not be showing you any signs of obvious pain, these types of things can be painful. Animals are very good at masking pain. I would also consider thinking about getting a second opinion. If you came away from a vet appointment being told you needed to amputate your dog's leg, but not really knowing why, you might want to find another vet who would be able to explain things a little better. But that is just a thought.

Thanks for using Petco Pet Education Center, formerly Petcoach! The fact that these biopsies have come back inconclusive does not mean that this is not cancer. Unfortunately, this is very likely an aggressive form of cancer. After seeing these images, my main concern is that this is possibly a tumor arising from one of the ribs or sternebrae such as osteosarcoma for instance. In one of the images I see that there is likely pulmonary nodules which are most likely due to metastasis or spread of this cancer. It is hard for me to advice further without being able to look at more images or know more about the case. I would encourage you to check in again with them as another biopsy could be performed. Also, if there is truly already signs of metastasis, the treatment options and prognosis are also limited. I would mention to them the possibility of being referred to a veterinary oncologist who can look at the case with more details and advice further. I really hope they can help you and your boy!
