How do oncology specialists treat pets with cancer?

Veterinary medicine has advanced along with human medicine, which means there are options when it comes to pets’ cancer treatments. Every pet is unique, and therefore each treatment plan we build together will be, too.

Our oncology team works closely with your primary care veterinarian and other specialties at the hospital to give your pet the best possible care. We know a cancer diagnosis can bring a lot of feelings, and we’re here to help you through the process to give your pet the best quality of life possible.


Most pet cancer treatment plans involve removing any tumors present to prevent the spreading of the disease. Surgically removing tumors is often the most effective option as long as the tumors are big enough and in a good spot to treat. Sometimes, the location or shape of a tumor may make it challenging to remove through surgery, or could cause greater risk to a pet’s health, so other treatments like chemotherapy may be used instead of or in addition to surgery.

Every patient is different, and no one treatment plan works for every pet. This is why we work closely as an oncology team, collaborating and developing a course of action with the primary goal of treating your pet’s condition and improving their quality of life.

Like humans, pets may undergo chemotherapy as part of their cancer treatment. Delivered via injection or pills, chemotherapy for pets targets fast-growing cells to eliminate cancer cells. How often and how long a patient will need to undergo chemotherapy is based on their physical condition, the type and severity of cancer they have and other factors like how well they tolerate the medication.

Unlike humans, most (80 to 90%) of cats and dogs receiving chemotherapy experience very minimal or no side effects. Some patients may have moderate to severe side effects, but it’s not very common, and rarely are side effects life-threatening to your pet.

Most often, chemotherapy is an outpatient procedure, but occasionally we will need a pet to stay overnight to complete their treatment. Before any procedures or diagnostics take place, your oncology care team – including your pet’s oncologist – will discuss treatments and your options, keeping you informed and involved in your pet’s care from the start.
