As well as an artist, Turner was an award-winning water skier, held an instructor level red sash in martial arts, and was an avid video game player. In March 2000, Turner was diagnosed with chondrosarcoma, a form of cancer, in the right pelvis. He was treated at the Ronald Reagan UCLA Medical Center with surgery in which he lost a hip, 40% of his pelvis, and three pounds of bone. The surgery was followed by nine months of radiation therapy.
