WHAT ARE GENES?
Genes make you and your pets unique. All of us are different because of slight differences in our genes, leading to variations in our features from one generation to the next. Our uniqueness also comes from the number of genes we carry. Humans have around 25,000 genes, dogs have about 19,000, and cats have approximately 20,000.
When the body is functioning normally, damaged cells have the natural ability to self-destruct, but this isn’t always foolproof. Sometimes, specific changes to genes can impair the self-destruct mode of altered cells, allowing them to continue to grow and divide. Uncontrolled growth may lead to a cancerous tumor. Sometimes, these modified genes are passed on from parent to offspring.
Understanding genes are essential for cancer diagnoses and treatment. For example, gene therapy, a new form of treatment for various genetic diseases like cancer, is emerging with a promise to improve the conditions of cancer patients. Gene therapy targets cells with abnormally modified genes and restores normal function, thereby slowing down or stopping the disease. Because this type of treatment is new, scientists are continuously researching how to make gene therapy an effective cancer treatment.
Learning about your pet’s genetics helps you appreciate what makes your beloved pet who they are. It also allows you to understand what health risks they face and what treatments are available. You can also discuss with your vet what new gene-related therapies are available to treat your pet’s cancer.
