Anastacia's cancer research
Anastacia researched mastectomies after a breast cancer scare in 2005.
The 47-year-old singer, who was first diagnosed with the disease in 2003 but made a full recovery, looked into having her breasts removed eight years before her second diagnosis in 2013 after a mammogram flagged something suspicious.
Speaking exclusively to BANG Showbiz, she said: "I had a scare two years after my first my cancer and I immediately researched mastectomies at that point. I almost got a prophylactic mastectomy prior to getting cancer again."
The 'I'm Outta Love' hitmaker made the brave decision to undergo a double mastectomy in October 2013 after she contracted breast cancer for the second time, but she's adamant the operation was a no-brainer out of fear it could spread to her organs.
She explained: "The problem with a lumpectomy [a procedure to remove the affected area] is you still have tissue that cancer can come back."
She added: "And that's why my decision was, 'I don't want another lumpectomy in the other breast so that maybe next time it's not just the lumpectomy, it's in the liver or somewhere else.'"
Since the mastectomy two years ago, Anastacia, who also battles with the chronic inflammatory condition Crohn's Disease - has undergone breast reconstruction and has admitted she's in the "best health" she's been for a long time.
