Girls Aloud singer Sarah Harding has been diagnosed with breast cancer, which she says has spread to other parts of her body.
Writing on Twitter, the 38-year-old told fans she was diagnosed with the disease earlier this year.
Harding explained she then received the “devastating news” this month that the cancer had spread.
“I’m currently undergoing weekly chemotherapy sessions and I am fighting as hard as I possibly can,” she said.
The singer thanked NHS staff, her family and friends for support, adding that she was “trying to keep positive”.
Harding said she had decided to go public with her diagnosis after being seen in hospital last week.
Her Girls Aloud bandmate Cheryl responded to the news by posting a broken heart emoji on Twitter.
Sarah Harding’s statement in full
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.
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. Earlier this year I was diagnosed with breast cancer and a couple of weeks ago I received the devastating news that the cancer has advanced to other parts of my body.
I’m currently undergoing weekly chemotherapy sessions and I am fighting as hard as I possibly can.
I understand this might be shocking to read on social media and that really isn’t my 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.
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.
I am doing my very best to keep positive and will keep you updated here with how I’m getting on.
In the meantime I hope you’ll all understand and respect my request for privacy during this difficult time. Sending you all so much love….xx
