Medical Oncology

Led by a team of board-certified veterinarians specialized in the field of cancer medicine, Penn Vet Medical Oncology provides care to cats and dogs with cancer.

We primarily treat patients with chemotherapy and other systemic medications, as well as investigational treatments through clinical trials when applicable and available.

These treatments may also be in combination with surgery and/or radiation therapy.

Penn Vet Cancer Care

Our approach to dogs and cats with cancer includes a complete health assessment so that owners can make the best decision with respect to treatment options.

The patient's quality of life is of paramount importance, and we strive to achieve not just prolongation of life through treatment but improvement in quality of life and alleviation of suffering.

Penn Vet's oncology service at Ryan Hospital is a member of the Comparative Oncology Trials Consortium (COTC) led by the National Cancer Institute. We collaborate with our human medicine counterparts to investigate new treatments through clinical trials in dogs and cat with cancer.

Participation in these trials provides your pet with access to novel therapies, while at the same time providing valuable information that can help improve treatment options for human oncology patients.

Making an appointment with the Medical Oncology service:

To set up an appointment with Medical Oncology, please call us at 215-746-6557.  

The Medical Oncology service sees dogs and cats with a diagnosis of cancer. Results from the primary veterinarian should be faxed to the oncology service prior to the appointment so that we can review the information and prepare requests for the remaining diagnostic tests that may need to be completed the day of the first visit.

Please have your local veterinarian complete all related forms (PDF) as part of the  referral.

Thank you for bringing your pet to Penn Vet Oncology for his or her cancer care. We have put together this summary of our policies so that you are prepared for what to expect during upcoming appointments.

  • Scheduling Future Visits
    • Please contact the Appointment Desk at 215-746-8387 to schedule future appointments for your pet. If you know that your pet will require weekly visits for his/her treatment, you can schedule many of these future appointments ahead of time for your convenience.

      Pets with unscheduled visits may need to return on a later date or may be charged as an Emergency visit.
  • Oncology Re-check Visit Procedures
    • The process for recheck visits through our service is different than our initial consult appointments. A treatment plan or recheck plan is typically recommended after the first extended visit. Therefore, for most recheck visits, a nurse or veterinary student will come to the lobby to greet you and your pet after you have checked in with the business office.

      Please have your yellow sheet completed, so that we can collect all the pertinent information regarding your pet’s status, side effects and refill needs.

      The oncologist in charge of your pet’s care will call you with an update and discussion of the next treatment when the physical exam and the planned diagnostics have been completed. If there is a significant change in status the clinician will call to discuss additional tests and arrange for a face-to-face consultation for a thorough discussion whenever needed.

      Please note that although you will not speak with the veterinarian when you arrive with your pet, you will speak with him or her during your pet’s time with us and/or when your pet is discharged to you.

      Your pet will be cared for by a team of oncologists and oncologists in training: This approach means that multiple clinicians are often involved in the care of your pet, so you will very likely see different clinicians at subsequent visits.

      All the cases are discussed in teaching rounds in the afternoon, so your pet gets the benefit of the collective knowledge of the entire team.

      Duration of Your Visit

      The average length of time that your pet’s recheck visit will take is 2-3 hours, sometimes longer depending on the diagnostic testing required; please make sure we can reach you by cell phone during this time. For your convenience, we offer a “drop-off” option as well. You can drop your pet off before 9 am and pick him or her up in the afternoon. You can schedule this “drop-off” appointment when you speak with the Appointment Desk staff.


      Unless your pet is going to be sedated or have chest x-rays or an abdominal ultrasound performed, you do not have to fast your pet prior to his or her visit. If it is recommended that you fast your pet prior to an appointment, please do not feed him or her after 10 pm the night before the visit, but continue to allow access to water. If your pet should not be fasted due to a medical condition (like diabetes) or is taking daily medications, contact the Oncology Service to find out what can be arranged.
  • Emergencies
    • If your pet is experiencing problems during working hours (8 am to 5 pm Monday through Friday) or you need to talk to one of the Oncology clinicians, please call the common oncology voice mail at 215-898-4805 and leave a message. An Oncology clinician or nurse will get back to you the same day.
    • If your pet is experiencing serious problems after hours or during the weekend, please bring your pet in to the Emergency Service for evaluation. The phone number for the Emergency Service is 215-746-8911.
    • The Emergency Service at Ryan Hospital can contact the Medical Oncology clinician on call if needed.
  • Non-Oncology Related Procedures
    • We are a specialty referral hospital, and our Medical Oncology clinicians and nurses are trained to treat and manage your pet’s cancer.
    • Other routine care procedures (such as vaccination and heartworm testing) as well as ear cleaning, nail trims, and anal sac expression should be performed by your primary care veterinarian.
  • Help Us Help You
    • Complete the yellow sheet, as it is especially important that you report side effects from the chemotherapy so we can make necessary adjustments in your pet’s treatment plan.
    • In order for you to let us know about your medication refill needs, check your pet's pill bottles before you come. If you run low, please call for refills before the day of the last pill.
    • If you choose to have blood work performed by your primary care veterinarian, please make sure copies of the results are faxed to us at 215-573-6049 before your next appointment with us.
  • Day by Day Pet Support
    • Day by Day Support is a grief support group, held the first Tuesday of every month
    • Dedicated telephone hotline, 484-453-8210, available 24/7
    • Weekly telephone check-in from Day By Day staff upon direct request from clients
    • Weekly online Support Chat, held each Sunday at 7:00 pm
  • Getting Involved
    • Help us fight cancer by supporting our research.
    • Cancer is a common cause of illness and death in both dogs and cats; too many of our patients die from their cancer despite the best of our efforts. Only through continued research and research support can we change this outcome.
    • The oncology service is actively involved in cancer research, including projects that focus on our own hospital patients only as well as multi-institutional and national clinical trials though our membership in the Comparative Oncology Trial Consortium.
    • We would be happy to talk with you about our research and how you can contribute to the work we do. Thank you for choosing the Penn Vet Medical Oncology Service. Together we can make a difference!
