Anastacia started writing 'Resurrection' before she had her double mastectomy.
The 47-year-old singer was diagnosed with breast cancer for the second time in early 2013 and, although it was a heartbreaking and scary time for the star, she has admitted the experience leading up to the operation to remove both her breasts gave her the inspiration she needed to pen her sixth studio album.
Speaking exclusively to BANG Showbiz, she said: "I started writing the album ['Resurrection'] before I had the surgery ... it wasn't easy but I like life. "
The 'Left Outside Alone' hitmaker - who was first diagnosed with breast cancer in 2003 but made a full recovery - underwent the mastectomy in May 2013, released her album less than a year later and went on tour 11 months ago.
Asked how she manages to stay so positive, she joked: "In real life I'm a cat. I'm not a real human-being, I'm actually a feline."
She added: "I've always been someone who will make light of a dark situation - very English sense of humour actually - so in the worst of times I'm going to make a really bad joke.
"I think being able to do that takes out the uncomfortable part when people don't know how to talk about what has happened. I'd rather just be the one letting it happen so the conversation can be more brighter."
