Liquid Biopsy and Circulating Tumor DNA: Where Veterinary Oncology Diagnostics Are Headed
Liquid biopsy is here. The question is no longer whether it has a role in veterinary oncology — it's understanding what that role is today and where it's going in the next few years.
Mammary Carcinoma in a Male Cat: A Diagnosis Worth Not Missing
Male cats can develop mammary carcinoma. The diagnosis should be on the differential list for any mammary region mass in a male cat, regardless of neuter status. Given that the vast majority of feline mammary tumors are malignant, histopathology is not optional — cytology alone is unreliable for distinguishing benign from malignant mammary lesions in cats.
Feline Injection-Site Sarcoma: Revisiting Pathogenesis in the Light of Current Evidence
And yet, more than three decades later, the pathogenesis of FISS remains incompletely understood. The broad strokes are established: chronic local inflammation at an injection site appears to trigger malignant transformation of fibroblasts or myofibroblasts in genetically susceptible cats. But the molecular details — what drives that transformation, why only certain cats develop it, and which specific pathways sustain tumor growth — are still being worked out.
