Caring for a Border Collie With a Spleen Mass and Lung Spread

by A reader

Reader Question
5/4/13 We took our Border Collie in to his vet for a routine shot. During the exam, the doctor noted a hard mass on his left side. An x-ray was taken and a "mass" was noted in the spleen. Further x-ray of his chest indicated that he had cancer in his lungs. The vet indicated that if nothing was done he would probably only live for approx. two months. If we had a splenectomy (removal of the spleen) he could possibly survive 4-6 months.

We were in shock over the findings and recommendations. He showed no symptoms of any problems. He is active, energetic and continues to eat and drink plenty of water daily. (Although we did note that he was 3 lbs lighter then the last vet visit. Other then that, he looks perfect, with shiny coat of fur, clear eyes and happy demeanor. We decided to think about the diagnosis over the weekend and make a decision for what would be in our beloved pet's best interest.

Ultimately, we decided not to have the surgery. We don't want him to have to undergo the trauma of surgery. Especially, if the diagnosis is correct and he only has a few months to survive. We had some blood work done, which was unremarkable and are now going for a second opinion. We have altered his diet, by only feeding him high protein, no grain,or sugar food (a prescription diet). We are also adding "fish oil" to his meals and will ask for a
vitamin to hopefully help him improve. Of course we are praying daily for a spontaneous remission, which we read can occur in a small percentage of these cases. We also have stopped throwing the ball to him. He is obsessed with chasing his ball. When we would throw it to him, he would jump in the air to catch it. We decided to make an effort to limit the intensity of his exercise to prevent the hemangiosarcoma from rupturing. After today's 2nd opinion, we will have more information on how to help him.


Answer from Our Team

I'm sorry. A spleen mass with nodules in the lungs is often hemangiosarcoma, but not always. Some spleen masses are benign, and the lung changes can sometimes be something else. Your second opinion is a good idea. An ultrasound of the belly and a chest scan can give a clearer picture.

Your plan sounds loving and sensible. Limiting rough play and jumping does lower the risk of a bleed. Learn the signs of internal bleeding: sudden weakness, pale gums, a swollen belly, fast breathing or collapse, and have an emergency plan. Some dogs recover from a small bleed, but a large one needs urgent care.

Diet changes and fish oil are fine if your vet agrees, but they won't stop this cancer. Ask the vet about chemotherapy options, which can extend life for some dogs even when surgery isn't chosen, and about a plan to keep him comfortable.
