Sarah Harding has reportedly been left terrified after undergoing tests to see if she has skin cancer.
The star should have been celebrating a stellar week after officially reuniting with her Girls Aloud bandmates on Friday, but was still reeling from a procedure to remove three moles on Wednesday.
Sarah underwent the procedure over fears the blemishes could turn out to be cancerous, according to The Sun.
A source told the publication, "This is an incredibly stressful time for her. It's early days and the doctors are very positive - but the word 'cancer' is terrifying to hear and Sarah is naturally stressing about it."
Her bandmates Kimberly Walsh, Cheryl Cole, Nicola Roberts and Nadine Coyle have rallied around their pal to ensure she doesn't stress out while awaiting the results.
The inside added: "The girls are completely behind her. Some of the fans have suggested she hasn't been enthusiastic about the tour, but the girls have told her not to stress because she'll only run herself down and make herself sick."
During the press conference, Kimberly told reporters how the girls were determined to look after Sarah, who had a tough 2011 after splitting from fiance Tom Crane and entering rehab.
The 'Strictly Come Dancing' star said: "It is important for us all to be there for Sarah, to put an arm around her and help.
"We all really noticed it when that daily business of being with each other was gone. We weren't there for each other every day."
