Anastacia is battling cancer for the second time

After finding out in February of this year that the cancer had returned, Anastacia was forced to cancer her tour.

There is no history of cancer in the singer’s family and Anastacia has previously spoken out about whether her stressful lifestyle and intense work schedule contributed to her breast cancer.

"More and more women today are getting cancer which is not gene related. I'm sure it was stress which caused mine."

"The not-so-great relationship I was in and my career - it all became too much for me. I'm not really made for this business. I don't really know how to be the star my record company always wanted me to be," she said.
