Docile dolphin gets cancer care at Illinois zoo

Brookfield Zoo outside Chicago is caring for an aging dolphin with cancer. His name is Lucky, and he's 500 pounds, mostly muscle, but still a very docile patient when it's time to be treated for his cancer diagnosis in the back of his mouth.

The zoo's medical director  says the treatment seems to be effective, but treating cancer in a pool brings its challenges. CT scans and ultrasound are used to make sure the cancer has not spread to the rest of Lucky's body.

Lucky was in Florida, but was flown to Brookfield Zoo in September where they can offer advanced treatment, and this is where he's going to stay. The veterinarians say his treatment could advance medicine for other animals and should keep this dolphin splashing for years to come.
