Anastacia has undergone a double mastectomy after being diagnosed with breast cancer for the second time.

The I’m Outta Love singer, 45, announced the news as she updated her fans on her recovery as part of Breast Cancer Awareness Month.

Anastasia, who said she underwent a double mastectomy with Latissimus Dorsi flap surgical procedure, was first diagnosed with the disease in 2003.

She then announced in February this year that she had been diagnosed with the disease again, and was forced to cancel her planned European tour.

Speaking previously about her successful battle against breast cancer, Anastacia blamed the stress of being a world-famous singer for her contracting the disease, as there was no history of breast cancer in her family.

In addition to battling cancer, Anastacia also suffers from a heart condition called supraventricular tachycardia – in which the heart can have episodes of beating more than three times as fast as average – and has to take a daily pill to regulate it.

She also has Crohn’s Disease – an inflammatory bowel condition that causes a range of distressing symptoms such as diarrhoea, vomiting, fevers and severe cramps.

But speaking recently about her health struggles, Anastacia said that her illnesses have helped shape her into the woman she is today.
