Dolly Parton canceled her planned Las Vegas residency, which had been rescheduled for September, saying she will pause performances to focus on medical treatment. In a video update titled "Good news and a little bad news," the 80-year-old said her condition is improving but she is not ready to return to the stage. Parton told viewers "everything I have is treatable" and asked for time to recover while she concentrates on treatment. The decision removes a major headline act from the Las Vegas calendar and delays new live appearances from one of country music's most enduring stars.
