On The Job
As a child, Dr. John Farrelly traveled to Ireland every year to visit family, and he loved working with the animals. He also loved science, so he decided to pair the two and study veterinary medicine. He chose the oncology and radiation oncology specialties because there are very few people in these fields. It’s important to him to offer specialized care for pets with cancer, and he finds it rewarding. While others might find treating cancer patients to be depressing, he considers it fulfilling to give pets a great quality of life for months to years after their cancer diagnosis.
Dr. Farrelly has stayed active in his field as a professional journal editor and manuscript reviewer. He has chaired therapy groups, reviewed certification exams, instructed at Cornell University and, as a consultant, provided biostatistics services for veterinarians.
Although there are a number of tumors that are challenging to treat, Dr. Farrelly finds nasal tumors in dogs and cats fascinating because they are surrounded by critical structures such as the eyes or the brain. In the past, treatment of these tumors often came with devastating side effects, but he has been able to watch and work with advances in technology, allowing for more rewarding treatment of these patients.
