Scheduling an Appointment

Veterinary Oncology Services and Research Center in West Chester schedules new case appointments Monday through Friday between the hours of 9:00 a.m. and 3:00 p.m. Appointments are generally available within 24–48 hours of the initial call. Please note that a new case appointment may take up to two hours.

For some cases, an ultrasound exam may be recommended as part of an initial workup. Our radiologist performs ultrasound exams on Tuesday and Thursday afternoons. We strive to schedule you and your pet efficiently so we can gather necessary diagnostic information during the first visit.

Initial appointments may be scheduled by pet owners or referring veterinarians. You do not need a referring veterinarian to schedule a consultation. A confirmed diagnosis of cancer is not required to make an appointment.


Please be prepared to provide the following information when scheduling a new case appointment:

  • Your name and phone number
  • Your pet’s name, breed, age, and gender
  • The name of your referring veterinarian, if applicable
  • The diagnosis or description of your concern

Treatment or follow-up recheck appointments are available Monday through Friday between 9 a.m. and 4:00 p.m. Patients can be dropped off for the day if owners cannot make an appointment time.


If you are preparing for your first appointment, please bring the following along with your pet or email in advance:

  • Copies of your pet’s records, including biopsy reports, recent blood results, or written results of any tests your pet has had.
  • Any radiographs, CT, or MRI scans that were taken of your pet.
  • Please print and fill out our canine questionnaire and bring it along to your first visit. If you have any questions regarding the questionnaire, please call (610) 692–6272 or email our research lab for help at vosrc@hotmail.com.

  • If your pet is a golden retriever, we ask that you please fill out our canine questionnaire. In addition, please bring along any information you may have about your pet’s breeding (this includes registration information and pedigree). With your permission, we may ask to collect a blood sample to include in our study of golden retrievers with cancer. For more information, please visit our page on research being conducted at VOSRC.
  • If you have any questions please call (610) 692–6272.

If you are already a client of VOSRC:

  • Please bring along (or fax) any blood work done by your local veterinarian, as well as any medications, including non-traditional medications or supplements you may be giving your pet.
  • If you have an emergency after hours and need to contact VOSRC, please use the pager number listed on your discharge sheet.
