How to identify a chest tumor on your pet's X-ray after a loss?

Updated On September 23rd, 2025

Pet's info: Cat | Himalayan | Female | spayed | 3 years and 4 months old | 12 lbs

My 3-year-old recently died to compound issues, but the worst was a massive chest tumor, that wasn't found until she was already in crisis. At the time I could not bear to ask the vet to point it out to me on the x-ray, but they did give me a copy to view later. I hoped it would be obvious to the untrained eye, but, I'm looking at it and guessing... I'd love an expert to help narrow what I'm seeing since I'm no expert at what I'm seeing.

First off, I'm so sorry Sasha died. Please accept my condolences for your loss. I wish I could be with you to explain this, but I will do my best. So her heart is completely obscured in this x-ray. You should be able to see the heart and both lungs in a normal x-ray. In this one, you can't see her heart or one of her lungs, that should be at the bottom of her chest. There is a big circular mass that the top right part of it touches the lung. I suspect that is the tumor. In addition, there are scattered white spots through the visible lung and in the chest. Those would be metastasis from the original tumor. Again, I'm so sorry and I hope this helps.
