A lung tumour is an uncontrolled growth of abnormal cells in the lungs. Primary tumours that originate in the lungs are rare in dogs but can be highly malignant, with the potential to spread to other body parts.
Secondary tumours are more common and occur when a cancer that originated in another part of the body spreads to the lungs.
Up to 25% of dogs with lung tumours may show no early signs, or mimic bronchitis or heart failure.
Some dogs may not show any respiratory signs, however.
Management depends on whether the lung tumour is primary or secondary. For primary lung tumours, surgically removing the portion of the affected lung is often recommended. Chemotherapy or radiation therapy can be added, or used by themselves if surgery is not an option.
For secondary lung tumours, chemotherapy is the primary treatment. Discussing a personalised management plan with your veterinarian and a veterinary oncologist is important for the best outcome for your dog.
The prognosis depends on the tumour type and your dog’s treatment response. With the successful surgical removal of a primary tumour and no sign of metastasis, the median survival times are 12 to 16 months. However, if a primary tumour has metastasised, the median survival time may be only two months. Unfortunately, secondary lung tumours also have a poor prognosis because of the dog’s late cancer stage.
Immediately contact your vet if your dog is having trouble breathing, has blue gums or tongue, cannot walk, collapses, or vocalises in pain.
It is vital to begin end-of-life care discussions before your dog‘s condition becomes unmanageable or they begin losing their quality of life.
