Pet Owners

The Human's Guide to Veterinary Cancer

What to Expect at Your First Appointment

You know your pet better than anyone else. We take the time to listen to you and answer any questions you may have about prognosis, treatment plan, nutrition, and how to keep your pet happy and comfortable during treatment.

Your first consultation will last an hour to an hour and a half. Your pet’s oncologist will perform a physical exam, review medical records, and discuss treatment options with you, which may include surgery, chemotherapy and/or radiation oncology. Any additional lab work or diagnostics will be done at this time. By the end of the appointment or when we have all the medical information we need, we will meet with you to discuss a plan. Some owners find they need time to make a decision about the next step. We understand, and we want you to know you will not need to make a decision that day. However, if you wish to begin you pet’s treatment immediately, we will make our best effort to accommodate your schedule.

You will receive a written report within three business days of your appointment. We also will send copies of your report to your primary care veterinarian for his or her records and confer with him or her throughout your pet’s treatment.

If you have any questions prior to your appointment, please call the office where your appointment is scheduled or email us for more information.

What to Expect

The professionalism and compassion shown by every staff member is unparalleled.


Advanced Treatment, Compassionate Care

You didn’t have to be a veterinarian to see that Sully was in trouble. A certified therapy dog, he arrived at our door with severe symptoms and advanced cancer. But just two-and-a-half months into a six-month chemotherapy regimen, Sully’s tumor was no longer visible on x-ray. Nine months after his therapy ended, with the blessing of his oncologist, Sully competed and won third place in a national agility trial.

Not only has the TOS clinical discipline been impressive, but we feel that Tyler’s safety, well-being and quality of life has always been at the center of TOS treatment recommendations.

As humans, we want to do everything we can for our pets, but we fear that cancer treatment will cause them to suffer. On the contrary, animals experience chemotherapy differently than humans, with minimal side effects, rare hair loss, and no fear of illness or treatment. At The Oncology Service, our goal is to extend quality of life, not cause needless suffering. We know you want access to the most advanced and innovative treatment, and it is our mission to provide it. At TOS we only treat cancer, and we have the expertise to provide your pet with the best possible outcome.

We understand that every family and each pet is unique. We work together with you and your primary veterinarian to determine the best treatment for your situation.

There Is More Than One Way to Fight Cancer

Bringing your pet to a cancer specialist is one of the most important steps you can take when your pet has cancer. We are experts in cancer treatment. Our experience, commitment to innovation, and access to resources allows us to use the most advanced and effective treatments to help you and your pet.

Medical Oncology

Medical oncology, or “chemotherapy,” is the use of medicines that are toxic to rapidly growing cancer cells. Simply put, chemotherapy destroys tumors. Your Oncology Service veterinarian will determine your pet’s treatment by following a protocol that includes the type and dose of drug, duration of treatment, possible side effects, and expected results. Your pet may need one or more cycles of treatment. Rest assured that we will closely follow your pet to control any discomfort and to evaluate the effectiveness of treatment.

Radiation Oncology

Just as in human medicine, some forms of cancer respond best to radiation therapy. We offer conventional definitive and palliative radiation therapy, as well as Stereotactic Radiation Therapy (SRT). SRT is used to treat tumors that are difficult to reach surgically, and is typically completed in one to four treatments over the course of a week, instead of the standard 15 to 18 treatments over three weeks. SRT is currently available only at our Leesburg location.

Integrated Nutrition

Complex medical problems require a holistic approach. Nutrition is particularly important while your pet is undergoing cancer treatment. We offer individualized nutrition plans through our partner, Cornell University College of Veterinary Medicine. Customized plans are available to support a range of nutritional needs, from reduced appetite to more serious conditions. These include specialized prepared diets, as well as menus and recipes for home cooked meals.

The Future of Cancer Treatment is Here

Kaya was a mixed-breed shepherd who came to us with a large tumor on her neck. The malignancy had gone unnoticed because of Kaya’s generous fur, and her family was devastated by her diagnosis. We were able to enroll Kaya in an investigational study of a novel cancer treatment, in her case an intratumoral bacterial agent, at no cost to her family. The Oncology Service is on the front lines of the battle against cancer. We use our experience, knowledge of the field, and understanding of novel therapies to help our patients live longer, healthier lives. Our unique relationships, such as with the research group Animal Clinical Investigation (ACI) and directly with pharmaceutical companies, allow us to bring our patients cutting edge treatments and enroll them in clinical trials, while they help us move forward the frontier of cancer care.

Clinical Trials

Your pet may qualify to participate in a research study. If your pet qualifies for an open clinical trial through ACI, and you choose to join, there is typically minimal or no cost to you. ACI has ongoing studies at various TOS locations. If you are interested in getting more information about investigational therapies or clinical trials, please contact our office nearest you.

When your pet has cancer, it isn’t easy to accept, and although this was our fourth round, it wasn’t any easier. Dr. Manley was absolutely wonderful every step of the way, explaining all our options and allowing us to make the decisions we felt were right for our dog and our family. Today, he is healthier and able to do everything he used to do. I couldn’t be more pleased with Dr. Manley and the staff of The Oncology Service.


Advances in Cancer Treatment Mean a Longer, Fuller Life for Your Pet

When we first met Ginger, she was not a happy cat. In fact, she was very sick and suffering from lymphoma, a form of cancer that is not uncommon in cats. Luckily for Ginger, her cancer responded well to treatment, and she was soon bird watching again from her favorite windowsill.

Your pet is part of your family, and we understand that a cancer diagnosis can feel devastating. Fortunately, most veterinary cancers are treatable, which means your pet can live a longer, happier life than ever before.

If your pet is diagnosed with cancer, it is important to gather information, learn about treatment options, and discuss them with your veterinarian. If you would like to know if your pet is a candidate for cancer treatment, you may ask your vet for a referral to a cancer specialist such as The Oncology Service, or contact us directly. We will develop a treatment plan that can help your pet live a longer, healthier life.
