Sarah Harding, a member of all-girls band Girls Aloud, is reportedly diagnosed with skin cancer and underwent a minor surgery for it last week.

Three potentially cancerous moles were reportedly removed from the singer's back on Wednesday, just two days before announcing Girls Aloud's upcoming album and tour. Further tests have been done to ascertain if the moles are cancerous and the results are expected this week.

The 30-year-old singer is said to be going through lots of stress because of the cancer scare, but her bandmates - Cheryl Cole, Kimberley Walsh, Nadine Coyle and Nicola Roberts - are by her side.

"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," The Sun quoted a source as saying.

"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," added the source.

Harding had earlier gone to a rehabilitation centre to beat her addiction with alcohol and sleeping pills.

The Girls Aloud members announced the release of their new single "Something New" just two days after Harding underwent surgery.

The five-member all-girls' band announced their comeback after 10 years last week. They will release their new single on 18 November 2012 and their second greatest hits called "Ten" on 26 November 2012. They also announced a tour called "Ten - The Hits Tour 2013".
