Dog Cancer: Early Detection Through Blood Testing Advances

Liquid biopsy and cancer marker blood tests for dogs are advancing, offering the potential for earlier detection when treatment is most effective.

Key Facts

Cancer is the leading cause of death in dogs over 10 years old
Current liquid biopsy tests for dogs detect some cancers months before clinical signs
Breed-specific cancer risks allow targeted screening in high-prevalence breeds
Early-stage cancer treatment has significantly better welfare outcomes than late-stage diagnosis

Welfare Considerations

Dogs with cancer often live with pain and discomfort for weeks or months before diagnosis. Earlier detection through blood screening enables treatment at a stage when quality of life during treatment is better and cure or remission is more achievable.

What You Can Do

Ask your vet about cancer screening tests available for high-risk breeds
Schedule increased vigilance health monitoring for dogs over 8 years old
Donate to canine cancer research programmes developing better screening tests
