Girls Aloud's Sarah Harding Shares Breast Cancer Diagnosis: "I Am Fighting As Hard As I Possibly Can"

Girls Aloud singer Sarah Harding, 38, said she "received the devastating news that the cancer has advanced to other parts of my body." Scroll on for her message to fans.

Sarah Harding has shared a heartbreaking health update with her fans.

The Girls Aloud singer took to social media on Wednesday, Aug. 26, to reveal that she was diagnosed with breast cancer earlier this year. "Hi everyone, I hope you are all keeping safe and well during these uncertain times. I've not posted on here for so long, thank you to everyone who has reached out to check in on me, it really does mean a lot," the 38-year-old began. "I feel now is the right time to share what's been going on. There's no easy way to say this and actually it doesn't even feel real writing this, but here goes."

After receiving the diagnosis earlier this year, Harding learned just weeks ago that the cancer has "advanced to other parts of my body." She noted that she's currently undergoing weekly chemotherapy sessions and is "fighting as hard as I possibly can."

The British star told her followers that she understands this might be "shocking to read on social media" but said that isn't her intention. "But last week it was mentioned online that I had been seen in hospital, so I feel now is the time to let people know what's going on and this is the best way I can think of to do so," she explained. "My amazing mum, family and close friends are helping me through this, and I want to say a thank you to the wonderful NHS doctors and nurses who have been and continue to be heroes."

After sharing the news, the artist received many well wishes from fans and fellow stars. Singer Cheryl Cole appeared to react to Harding's message on Wednesday, posting a broken heart emoji on Twitter.

Fellow Girls Aloud member Nadine Coyle also reacted to the heartbreaking news. "I love you!!!! You have always been able to achieve miracles when needed!!" Coyle commented on her friend's Instagram post. "I am here for the all the way & always will be!!!"
