To diagnose cancer accurately, we often need to examine cells or tissue under a microscope. Cytology involves using a fine needle to collect cells, while a biopsy takes a small piece of tissue for more detailed analysis. These procedures help us identify the exact type of cancer, how aggressive it may be, and what treatment options are most appropriate.

Many samples can be collected during a quick outpatient visit, often with light sedation or local anesthesia. The tissue or cell samples are then sent to a veterinary pathology lab for expert interpretation. A definitive diagnosis is key to making informed decisions about your pet’s care, and these tests are often the first step toward developing the most appropriate treatment plan for their condition.
