Anastacia has revealed she is battling breast cancer for the second time.
The I'm Out of Love songstress took to Facebook to break the news of her diagnosis, admitting her heartbreak at having to cancel her European tour to undergo treatment.
The 44-year-old said she is determined to beat the disease again, encouraging sufferers to live by her motto: "Don't ever let cancer get the 'Best of You!'"
A spokesperson for the star wrote: "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."
The singer first survived breast cancer back in 2003 and has since become an inspiration to fellow sufferers - publicly speaking out about her refusal to let cancer beat her.
In the UK alone, around 50,000 women are diagnosed with breast cancer each year.
It remains the most commonly diagnosed cancer in the UK, with one in eight women developing breast cancer at some point during their lives.
Yet new improvements in screening, treatment and better awareness mean more women than ever in the UK are surviving the disease.
Celebrities, such as Anastacia, who choose to speak out about their battle with the disease are helping to highlight the importance of regular breast checks.
Eluned Hughes, of Breakthrough Breast Cancer, told us: “When celebrities feel comfortable to talk about their own experiences with breast cancer it really does help to raise important awareness of the disease.
"We’re privileged to have a fantastic selection of celebrities support our breast awareness campaign, Touch, Look, Check (TLC).
“Celebrity involvement in our TLC campaign has continued to have a huge impact. Their standing in the public eye means that we’re able to get even more women talking about their breasts and the signs and symptoms of breast cancer."
The spokesperson added: "We know that more than half of UK women are still not regularly checking their breasts, and the level of publicity a celebrity can bring is invaluable if we are to stop women dying from breast cancer.
“We’re sorry to hear about Anastacia’s news and we wish her the very best with her treatment.”
Elsewhere, Kristin Hallenga, founder of UK-based breast cancer charity Coppafeel, said celebrities speaking out not only raises awareness, but also helps to alleviate women's fear of checking their breasts.
"People like Anastacia help to get talk of the disease into people's minds," she told us.
"The fact that she's speaking about what she's going through is so important as it encourages women to talk about breast cancer and stamp out the fear of checking their breasts."
The charity aims to raise awareness and educate young women into getting into the habit of knowing how their breasts look and feel normally.
And Kristin says getting women used to checking when they're young could be life-saving later on.
She explained: "A key message for us is to get young people thinking about it.
"If they are already talking about cancer and noticing any changes in their bodies then, they'll be more likely to know the signs when they're older and higher risk."
