Fortunately for all of us, there are now tests available to determine if our dogs might have some kind of cancer. These tests are called molecular diagnostics because they detect changes at the cellular level in body fluids such as blood, urine, saliva, and milk.
Molecular diagnostic testing uses small samples of fluid or tissue to examine cells to see whether there are any signs of disease present. Some examples of diseases include leukemia, mast cell tumors, thyroid conditions, and others.
