DNA sequencing and molecular testing allow us to examine cancer at the genetic level. These tests identify mutations or other changes in tumor DNA that can affect how the cancer behaves, and which treatments are most likely to be effective. This information can help guide the use of targeted therapies or assist in diagnosing complex or unusual cases.

Samples for these tests are typically obtained from biopsy tissue, but in some cases, they can also be collected from fine needle aspirates. The samples are analyzed by specialized laboratories that provide detailed genetic information about the cancer. While not required in every case, these tests are especially helpful when conventional treatments have failed or when a more precise approach is needed to support your pet’s care.
