Original publication title: Comparison of Fine-Needle Aspiration and Core Needle Biopsy for the Pre-Operative Diagnosis of Canine and Feline Mammary Gland Tumours.
Plain-English summary
A study looked at how well fine-needle aspiration (FNA) and core needle biopsy (CNB) can diagnose mammary gland tumors in female dogs and cats before surgery. For cats, both methods were quite accurate, with results showing 90% to 97.7% accuracy. However, for dogs, the accuracy was lower, ranging from 46.7% to 73.6%, depending on the type of biopsy used. This means that while both techniques can help identify tumors, they work better for cats than for dogs. Pet owners should discuss these options with their veterinarian if their pet is diagnosed with a mammary tumor.

Abstract
Mammary gland tumours are common neoplasms that affect female dogs and cats. We compared the accuracy of pre-surgical fine-needle aspiration (FNA) and core needle biopsy (CNB) diagnosing feline (n = 64) and canine (n = 83) mammary gland tumours with excisional histopathology as the gold standard for the definitive diagnosis. We also explored the impact of CNB needle sizes (18G and 16G). FNA, 18G CNB and 16G CNB demonstrated similar accuracy regarding the diagnosis of feline mammary tumours, ranging from 90% to 97.7% (p > 0.05). However, these techniques displayed lower diagnostic accuracy for canine mammary gland tumours: 46.7%-50.9% for FNA, 63.3% for 18G CNB and 73.6% for 16G CNB. In conclusion, FNA and CNB can be used optionally as pre-surgical diagnostic methods for feline and canine mammary gland tumours. However, factors that affect diagnostic accuracy, such as species and diagnostic techniques, should be considered.
