Fine-needle aspirate (FNA) & biopsy
The first step for any lump is not surgery — it's a fine-needle aspirate: seconds of cell sampling for microscopy to classify the lump (lipoma, cyst, tumor). Only a needle mark, most pets need no sedation.
🧾 Avant l'examen
- ✓No fasting unless sedation is planned
- ✓Note when the lump appeared and how it changed
- ✓Photograph and measure it

💡 Comment l'interpréter FNA accuracy is roughly 70-90%; if no cells are obtained, a biopsy (core needle or excision) follows. For cancer-prone breeds (Goldens, Boxers), new lumps get checked within 48 hours.

Questions fréquentes
Can FNA spread tumors?
Implantation from fine-needle aspirates is extremely rare (few exceptions) — the risk of delayed diagnosis far outweighs it.
How often should lumps be checked?
New lumps immediately; confirmed-benign lumps monthly with photo size comparison.
