Clinical Trials Providing hope for future cancer patients. About Clinical Trials

One in four dogs and one in five cats will develop cancer in their lifetimes. Forty years ago, cancer was often a terminal diagnosis with few options, especially for pets. Today, there is hope.

The Flint Animal Cancer Center at Colorado State University offers a unique combination of advanced cancer diagnostic services, innovative treatment options, and compassionate care for dogs, cats, and other pets with cancer. As a patient, your pet will benefit from a comprehensive assessment provided by an expert, multidisciplinary team, including medical, surgical, and radiation oncologists. Each treatment plan is customized, and we work with you to determine the right course of action for your pet’s care.

We are a world leader in the treatment of dogs, cats, and pets with cancer, with nearly four decades of experience in providing leading-edge, comprehensive, and compassionate care.

Our goal is to make sure that you are fully informed about your pet’s diagnosis and treatment options, so you are comfortable asking questions and making decisions. You are a key member of your pet’s cancer care-giving team. Our clinical staff is committed to helping you understand your pet’s cancer treatment and will offer support every step of the way.

Our vision is to conquer cancer in all species.
