My 11-year-old dog has a tail lump. Should he get cancer surgery?

At the age of 13 surgery in this location may actually not prolong your dog's life, but actually cause him more suffering, as, in order to remove this fairly large tumor, parts of the tongue and neck tissue may need to be removed. This will take a while to heal, be painful and will interfere with eating. I think you can trust your vet with the assessment. If you would like a second opinion, consult with a veterinary oncologist. I am sure your vet can refer you to one and will not mind.

If your vet recommends removing the growth, it's likely a good idea. In a senior dog like Cookie, there is always a chance it could be cancer, which is why it's ideal to remove it to prevent it from spreading. If the growth is cut out with wide margins and the cancer hasn't already spread, it is possible that it can be cured completely without further treatment. The vet will do everything they can to remove the tumor fully, and I would imagine they would let you know if there was a concern that it couldn't be removed completely or if she wouldn't heal properly. I do advocate for removing growths in a senior dog especially if there is a concern it's cancer, but I highly recommend speaking to your vet about your concerns. Having an in-depth conversation with them may help allay your worries. I hope this helps!

Place an e-collar (cone) on him to prevent licking or chewing until he sees the doctor. A fine needle aspirate or other biopsy can be done to collect samples for pathology. This may provide a diagnosis. Treatment options can be discussed once results are returned.

Unfortunately, cancer is always a possibility in a senior dog like Mufasa. Any suspicious lumps should be examined by the vet. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of it's cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. I would have Mufasa seen by a vet tomorrow to have the lump examined and diagnosed so it can be treated.

Thank you for using Petco Pet Education Center, formerly Petcoach! I can see that Jake has a very large, round, well demarcated growth on his side. While it is impossible to tell exactly what type of tumor it is and give a prognosis following removal, it is likely that removing the tumor will make him more comfortable. Depending on the approach, the surgical site may be rather large and require some care and pain management at home. As long as Jake is otherwise healthy, surgery and anesthesia are relatively safe as well. I hope this helps and am happy to answer any other questions you have!

Thank you for providing pictures of the lump on Skip's tail. It is possible, given his age, that he could have a malignant tumor causing the lump. It could also be a benign tumor. I would not rush him into an ER vet tonight, but I would have him seen by a vet tomorrow if possible for a fine needle aspirate. To do this, the vet sticks a small needle into the lump to get a sample of it's cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. Once the cause of the lump is found, the vet can discuss treatment options if needed. I hope this helps :-)

With any new lump or lump that is changing, it is always best to have your veterinarian look at them and a fine needle aspirated can be done to obtain a sample of cells. If these cells look suspicious of a malignancy, then your vet can recommend surgery. From the photos that you have posted, my guess is that these may be benign, non-cancerous masses. These can still cause problems, though, by bleeding and getting infected. I would schedule Max for an exam at your earliest convenience so that you and your vet can weigh the pros and cons of surgery since he is a senior.
