Trina Hazzah

Trina Hazzah was born and raised in Washington D.C. She attended Tuskegee University School of Veterinary Medicine, where she earned her Doctor of Veterinary Medicine in 2006. She completed her small animal internship at Red Bank Veterinary Hospital in New Jersey and a 3-year residency in medical oncology at the Veterinary Oncology and Hematology Center in Connecticut. She has also completed the requirements to be a Certified Veterinary Chinese Herbalist.

Dr. Hazzah's area of interest is Complementary and Alternative Medicine (CAM) and she offers a novel approach to veterinary cancer therapy by combining conventional Western therapies with complementary Eastern therapies to provide a "whole patient” treatment approach. The goal of combining Eastern and Western therapies is to better support the immune system, decrease side effects from cancer or cancer-related treatments (chemotherapy or radiation therapy), enhance the quality of life, and improve survival for the cancer patient.

Dr. Hazzah feels that quality of life is an essential priority in the treatment of her cancer patients and strives to find a perfect balance between effective treatment and maintaining patient comfort.

Dr. Hazzah developed an interest in cannabis medicine during her quest for finding effective integrative approaches for pet cancer patients. She has spent several years critically evaluating the available literature, attending multiple cannabis conferences and symposiums, participating in cannabis-related advocacy work and learning from cannabis physicians. She has since given numerous lectures to veterinarians educating them on the topic of cannabinoid medicine.

In addition to conventional oncology consultations, Dr. Hazzah offers integrative oncology consultations for clients who are interested in treating their pet with integrative and alternative medicine.

What Is A Veterinary Oncologist?

A board certified veterinary oncologist is a veterinary specialist who has obtained advanced training in veterinary oncology, passed board certification examination in either medical or radiation therapy and has earned the right to be called a recognized specialist by the American Veterinary Medical Association (AVMA). Both have specialized knowledge in the diagnosis of cancer, staging and treatment of cancer, however the focus of a radiation oncologist is in the use of radiation therapy, whereas the emphasis of the medical oncologist is in the use of chemotherapy and other non-radiation cancer treatment modalities. When your pet is faced with cancer, a veterinary oncologist will typically work in concert with your pet's general practitioner veterinarian in order to obtain the best possible medical outcome for your pet. A veterinary oncologist can help your pet by developing diagnostic and treatment plans that may include one or all of the following options:

  • Surgery
  • Radiotherapy
  • Chemotherapy
  • Vaccine or Immunotherapy
  • Bone Marrow Transplant

While your general practitioner veterinarian can diagnose and treat many health problems, certain diseases like cancer require the care of a doctor who has had specialized, intensive training in veterinary oncology and can assist you in the decision making process, treatment and long term care of your pet.

Why Does My Pet Need A Veterinary Oncologist?

Just as in humans, a pet with cancer typically needs the help of an oncologist to help diagnose and treat the disease. Veterinary oncologists determine the most appropriate course of treatment and coordinate the treatment program for pets with cancer. They also frequently serve as consultants to veterinarians in private practice to ensure that their patients receive the best treatment possible for their cancer. You can be assured that a veterinarian who refers you and your pet to a veterinary oncologist is one that is caring and committed to ensuring that your pet receives the highest standard of care for his or her illness.

While in some cases, your veterinarian may be able to simply consult with the veterinary oncologist about your pet's care, in other cases it is necessary to actually refer you and your pet to the veterinary oncologist for more advanced diagnostics and treatment. Board certified veterinary internists/oncologists may also have access to specialized diagnostic or treatment tools that a general practitioner veterinarian may not have.

My Pet Has Cancer. Now What?

Cancer does appear to be becoming more common in pets, most likely because they are simply living longer. The most important point to realize about this dreaded disease, however, is that just as in people, many forms of the disease can be easily treated, managed, and even cured. Early detection and specialized care are leading to increased survival and cure rates in almost all the types of cancers that afflict pets. From surgery to chemotherapy to radiation therapy, veterinary cancer specialists can offer your pet the very latest diagnostic and treatment options and the best chance of survival. With optimal treatment, cancer in many cases simply becomes another manageable chronic disease.

If your pet is diagnosed with cancer, it is important not to become overwhelmed. Ask your veterinarian to write down the most important points for you to review later. Although the disease is serious, treatment decisions generally do not need to be made quickly. If your pet is diagnosed with cancer, you will either want to have your general practice veterinarian work in consultation with a veterinary oncologist, or refer you to one for your pet's treatment.
