Anastacia, an American pop star who made it big in Europe and Australia, has announced that she will be canceling her European tour because of a second breast cancer diagnosis.
Anastacia, 44, made her way to international fame with her 2000 dance track "I'm Outta Love" and successfully battled breast cancer in 2003.
Her "It's a Man's World Tour" was set to kick off in London on April 6 but has been canceled until further notice.
"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 singer said on her website.
The "Sick and Tired" singer still plans to write and record her upcoming album and hopes to reschedule her tour, according to a statement posted on the website.
"Now more then ever, she is determined to live by her motto 'Don't ever let cancer get the 'Best of You!'" the statement said. "A born survivor, Anastacia has one goal and that is to make a full recovery with the support of her family, friends and everyone around her."
An outpouring of fan support -- in English, Italian, German and French -- landed on the singer's Facebook page, where the announcement also was posted.
Anastacia, whose full name is Anastacia Lyn Newkirk, was diagnosed with Crohn's disease, a chronic intestinal illness, at age 13. She went on to become a dancer, appearing in a few Salt-N-Pepa music videos, according to her iTunes bio. She was discovered on MTV's talent show "The Cut" and later, in 2002, went on to join Mary J. Blige, Cher, Shakira and others for VH1's fifth "Divas Live" showcase.
She has since recorded several albums, launched a fashion line and toured globally.
