My dog has swelling where a thyroid tumor was removed. Is it back?

Hello, Unfortunately, it is very possible that his cancer has returned. I would recommend getting Harley a recheck as soon as possible with his vet to better understand what is happening with his weight change and testicular swelling. Harley will be in my thoughts. Thanks for using Petco Pet Education Center, formerly Petcoach.

The ends of the incision look infected and very painful. She should be rechecked right away for medication for pain and swelling and further antibiotics. She may need some parts opened and drained and flushed to help minimize the infection. If the tumor was cancerous and it was not completely removed, then there is a change the cells are angry and irritated and growing again from inflammation. Try to apply a warm compress and keep the area clean until you can get her in.

Thanks for the pictures! At 5 months of age (nearly 6!) I doubt very seriously this is cancer, but if an abscess was in this location and is now back it suggests to me that whatever caused the abscess is still there. It's likely that he's going to need a bit of surgery to explore and drain the area. There may be some plant material or other foreign object stuck there, deep under the skin.

I'm very sorry to hear that, it's because the tumor was probably not removed entirely or because it is a malignant tumor that has already spread to other places. you will need to take him back to the vet to get it checked and assessed, your vet might tell you that it should not be operated again if he thinks it will keeps growing back.

If it has come back after the initial course of treatment, I would see if your vet can perform a fine needle aspirate and send it out for cytology review with a pathologist. This will help determine if the lymph node in question is suspicious for lymphoma or not. Hope this helps! Please let me know if you have any further questions / concerns. I am also available via consultation.

I would be concerned that the swelling is another mammary mass or lymph node from the mammary area. Unfortunately, needle aspirates on mammary cells can be hard to determine if malignant or not. I would recommend taking Aries in to your vet tomorrow to discuss the next steps. I think your vet will also suggest chest xrays to make sure there is no evidence of cancer in her lungs.

If I read this correctly your dog's leg was swelling to this size within a few hours. If your vet took x-rays and found bone lesions then there is indeed a possibility of bone cancer. However only a biopsy of the bone or the tissue of the swelling will prove that there is cancer. Without the possibility of examining the leg myself I can only give you possibilitites of why there is a swelling: 1) Check for puncture wounds or an injury. this could be a peracute infection of the joint. 2) this may be an injury of the joint such as a fracture or tendon injury, You should take your dog back to a veterinarian for an exam, especially since this is painful.
