In 2004, Twain retired from performing and retreated to her home in Switzerland. In her 2011 autobiography, she cited a weakening singing voice as the reason for not performing publicly. When both her singing and speaking were affected, Twain consulted the Vanderbilt Dayani Center in Nashville. Specialists discovered lesions on her vocal cords and diagnosed her withdysphonia, all treatable with careful rehabilitation. In 2012, Twain returned to the concert stage in her critically acclaimed showStill the One, exclusively at The Colosseum at Caesars Palace.
