Cancer Care

Today, there are many options available to treat pets that have been diagnosed with cancer. We are trained and equipped to safely administer chemotherapy and we will work with you and your family veterinarian to determine what course of therapy is best. Our goal is always to maximize effectiveness while maintaining good quality of life. Fortunately, pets experience chemotherapy much easier than humans, and our focus is always on their well-being during treatment. Although a cancer diagnosis can be frightening, there is much that can be done to extend your time with your pet.

What should I expect during a visit with a board-certified small animal internist?

Dr. Byers will perform a complete and thorough physical examination of your pet, and based on these initial findings, additional tests may be recommended. Depending on your pet's condition, diagnostic testing or treatments may include:

  • Advanced laboratory testing of various tissue and blood samples
  • Diagnostic imaging - ultrasound, radiography (x-rays), CT scans
  • Biopsies of masses, internal organs, or bone marrow
  • Endoscopy - bronchoscopy (lungs), cystoscopy (bladder & urethra), colonoscopy (colon), esophagoscopy (esophagus), gastroduodenoscopy (stomach & upper intestines), rhinoscopy (nasal cavity)
  • Feeding tube placement
  • Nutrition consultation
