Singer Delta Goodrem talks about losing her voice at the age of 30

Delta, 40, is one of Australia's most decorated female singer-songwriters. The former partner of Westlife singer Brian McFadden signed her first recording contract at only 15 years old and her 2003 debut album 'Innocent Eyes' topped charts for 29 weeks. Before embarking on her first world tour at 18, Delta was diagnosed with non-Hodgkin's lymphoma, an aggressive type of blood cancer.
