The impact of cancer on humans and pets is enormous today, and according to the American Veterinary Medical Association (AVMA) the number of pets with cancer is growing each year. In fact, the AVMA states that approximately 1 in 4 dogs will develop a tumor of some kind in their lifetime, and the Veterinary Oncology and Hematology Center approximates that cancer accounts for nearly 50% of all disease related pet deaths each year.
