Did you know that companion animals, like dogs and cats, naturally develop many of the same diseases as humans? Statistics show that over 4.2 million dogs naturally develop cancer each year, in comparison to 1.7 million humans. Dogs are actually a very important model for studying diseases, such as cancer, because not only do many dogs naturally develop cancer in their lifetimes, but cancer tumors in dogs are similar to those found in humans affected with the disease. A recent Forbes article discusses the importance of dogs in the biomedical research community’s mission to find a cure for cancer in both humans and animals.
Dogs are also excellent models for cancer studies because they live in the same types of environments as humans, meaning they are exposed to the same bacteria, household products, noises and other stimuli as we are. Dogs also age more quickly than humans. Have you ever heard the saying, “1 human year equals 7 dog years?” Well, for studying diseases like cancer, this popular belief becomes useful. Because the lifespan of a dog is shorter, it experiences the different stages of cancer much more rapidly than humans. This allows researchers to collect invaluable data in a speedier manner than when collecting data from human cancer patients.
Mice, which make up ~95% of all animals used in biomedical research, are excellent models for most areas of research, but dogs provide a unique model for finding cures and treatments for cancer in both humans and animals.
