Singer Anastacia has cancelled a scheduled performance in Dubai as well as an upcoming European tour after being diagnosed with breast cancer for a second time.
The singer, 44, released a statement earlier today postponing all performances until further notice.
She was given the all clear from her first bout of breast cancer in 2003.
The singer said in a statement via Facebook: "I feel so awful to be letting down all my amazing fans who were looking forward to 'It's A Man's World Tour'.
"It just breaks my heart to disappoint them."
She said her motto was “Don't ever let cancer get the 'Best of You!'” and was described by her management team as "a born survivor".
The statement said Anastacia will continue the writing and recording of her new album despite her diagnosis and hopes to schedule a new tour as soon as possible.
The "I'm Outta Love" singer has had multi-platinum album sales in Europe, Australia and other countries.
She had been due to perform the Dubai World Cup horse race on 30 March and her European tour was set to begin in London on 6 April.
A plea to respect Anastacia's privacy was made by her management team who also said that all tickets from the tour will be fully refunded.
