DNA Genetic Testing is used to help pets with cancer!
Let’s delve into DNA genetic analysis! What exactly is it?
Genetic testing, also referred to as DNA testing, involves the use of technology or DNA sequencing to identify abnormal changes in genes, chromosomes or proteins. These changes, termed mutations or variants, often contribute to the formation and progression of cancer. DNA genetic testing is routinely used in human medicine and is anticipated to become a standard in veterinary oncology.
How can DNA genetic testing help my pet with cancer?
When DNA mutations or variants are identified through genetic testing, chemotherapy drugs that specifically target the identified mutations can be recommended as treatment for your pet’s cancer. Although DNA genetic testing is not perfect and may not always yield results, it can often help you and your veterinary oncologist make informed treatment decisions and can provide additional insights into prognosis for your pet. This precision allows veterinary oncologists to use precise and targeted chemotherapy to treat cancer, which decreases the risk of chemotherapy side effects.
DNA genetic testing can be especially helpful in challenging cases in which treatment options are limited. Ultimately, our goal is to extend your pet’s survival time past what is expected with conventional chemotherapy. By specifically targeting the mutations identified in your pet’s cancer, many times, targeted chemotherapy and conventional chemotherapy can be safely combined.
What samples are necessary for DNA genetic analysis?
Samples required for DNA genetic testing are typically obtained non-invasively. Depending on the specific test, blood, fine needle aspirates, or biopsy samples are necessary.
Is DNA genetic testing available for both dogs and cats?
Unfortunately, DNA genetic testing is exclusively available for dogs. However, there is hope that it will soon become accessible for cats.
My dog has been diagnosed with cancer. Is DNA genetic testing the next step?
Maybe! Not all cancers are treated equally, and chemotherapy is not always the chosen course of action. Sometimes, surgery alone might suffice for treating your pet’s cancer.
