47-Year-Old Dolphin Back Home at Brookfield Zoo for Cancer Treatment
 

Brookfield, Ill. — The Chicago Zoological Society (CZS), which manages Brookfield Zoo, has welcomed back home Lucky, a male bottlenose dolphin who previously resided at the zoo’s Seven Seas. However, his homecoming is bittersweet—Lucky was recently diagnosed with an oral tumor.

The 47-year-old marine mammal was diagnosed in June by veterinarians at an accredited facility, where he has lived since leaving Brookfield Zoo in 2008. With test results confirming that Lucky is in otherwise great health for his age, CZS veterinary and animal care staff began making plans to bring him back to the zoo for further diagnostics and treatment.

Dr. Mike Adkesson, vice president of clinical medicine, and two marine mammal care specialists from Brookfield Zoo, made the trip to observe and spend time with Lucky prior to the flight to Illinois. And, this past week, the staff accompanied Lucky when he was flown to Chicago’s O’Hare International Airport thanks to the generosity of FedEx.

The tumor, which was evaluated by pathologists from the University of Illinois Zoological Pathology Program is a squamous cell carcinoma—a cancer that has been seen in dolphins in the wild and under human care.

“Brookfield Zoo is one of less than a dozen zoos and aquariums with a CT scanner on site. Having this diagnostic capability here at the zoo’s Animal Hospital allows us to continue to closely monitor Lucky’s condition and response to treatment,” said Adkesson. “In the weeks ahead, our team will be working with veterinary oncologists and surgeons to develop a treatment plan for Lucky. We are hopeful and optimistic that we can treat his condition and provide him more healthy years ahead.”

For now, Lucky remains out of public view as he receives medical care and observation, and will remain at Brookfield Zoo during and after his treatment.
