In this episode of Tripawd Talk Radio Episode #133, we talk about this groundbreaking research with Dr. Maureen Griffin, a surgical oncologist leading the way with innovative treatments at Colorado State University’s Flint Animal Cancer Center.
When a pet is diagnosed with cancer, one of the biggest questions pet parents face is not just what the cancer is, but where it may be headed next.

Dr. Griffin explains how minimally invasive techniques can reduce pain, shorten recovery time, and sometimes allow diagnostics and treatment to happen during the same procedure. The conversation also dives into sentinel lymph node mapping, a technique used to identify the lymph node most likely to be the first site of cancer spread, even when imaging looks normal.
This episode is especially relevant for pet parents navigating cancers like mast cell tumors, anal sac tumors, and other cancers where lymphatic spread plays a major role in treatment decisions.
Key Takeaways:
- What minimally invasive cancer surgery looks like in veterinary medicine today
- Why CT scans alone may miss early lymph node metastasis
- How sentinel lymph node mapping can influence treatment planning
- What questions pet parents can ask their veterinary or oncology team
