Why wait? Aspirate.
Dr Sue Cancer Vet
When a skin mass is the size of pea or larger or has been present for 1 month,
Aspirate or biopsy, and treat.
No, not even the most experienced veterinarian can look at or feel a mass and know if it is cancer or not. Your veterinarian must perform an aspirate or biopsy to make an accurate diagnosis.
Early detection saves lives.
