US singer Anastacia cancels Europe tour due to cancer

US pop singer Anastacia has announced she is cancelling her "It's A Man's World" European tour after being diagnosed for the second time with breast cancer. "Anastacia has sadly been diagnosed with breast cancer for the second time after having successfully survived her 2003 battle with the disease," a statement on the singer's Facebook page said Thursday. "Consequently she has been forced to cancel all performances, tours and any travel from now until further notice." The LS agency organising her concert in Austria meanwhile confirmed the April 20 date in Vienna had also been cancelled. Anastacia, 44, is best known for her chart-topping hits "One Day in Your Life," "I'm Outta Love" and "Left Outside Alone." "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," the 44-year-old said in her statement, adding she hoped to plan a new tour soon. All tickets for the "It's A Man's World" tour, which was due to kick off in London on April 6, can be refunded.
