In July 2009, Hallyday was diagnosed with colon cancer, and underwent surgery. On 26 November 2009, Hallyday underwent surgery in Paris to repair a herniated disc. He suffered complications and was admitted to Cedars-Sinai Medical Center in Los Angeles. Doctors announced that they had put Hallyday into a medically-induced coma so they could repair lesions that had formed as a result of the surgery, and to relieve his pain. On 17 December 2009, Hallyday and his wife started legal proceedings against Dr. Stephane Delajoux, who had performed the original surgery. The conflict was resolved in February 2012 following Delajoux's vindication by medical investigators.
