Dannii Minogue has opened up about the devastating time her pop star sister Kylie was diagnosed with breast cancer in 2005. 

The Australian singer, 53, revealed she was caught between grief and happiness when her sibling, 56, was declared cancer-free following surgery and chemotherapy.

While she celebrated the recovery of the Padam Padam hitmaker, she told Stellar on Sunday she was also grieving her friend Laura who died of cancer at the same time.

‘I remember when Kylie was really sick and there was a chance we were going to lose her,’ Dannii said.

‘As she recovered and the world was celebrating, and we all were too, I lost my best friend to cancer and I was grieving. There was this celebration and grieving.’

Dannii first revealed the private tragedy she suffered amid her sister’s recovery in October.

The All I Wanna Do star broke down in tears as she discussed Kylie’s battle with breast cancer during an appearance on ABC’s Take 5 with Zan Rowe.

Dannii tearfully opened up about the severe mental toll the 2005 diagnosis had on the superstar siblings and explained it coincided with the death of her closest friend. 

‘My sister got sick with breast cancer in the middle of a tour. I remember her being carried off stage,’ a tearful Dannii began.

‘I was visiting her when she was having chemo and very unwell. I would jump around to music with her, in the process of getting her better, music carried us through.’

Kylie was diagnosed with breast cancer in 2005 while in the middle of her Showgirl: Greatest Hits world tour.

After a partial mastectomy and rounds of radiation and chemotherapy, Kylie was given the all-clear the following year. 

Dannii added her sister asked her to join her onstage for a duet once she got better, and the joy she felt performing alongside Kylie several months later was incredible.

‘It was unbelievable, you could feel the roar from the audience, and we felt that all the way, the love and support was there.’

The Melbourne-born star went on to reveal how her closest friend Laura also battled cancer and sadly died at the same time Kylie received her diagnosis and recovered.

‘My sister had cancer, recovered, it was a wild ride for our family. And then my friend Laura had cancer,’ Dannii said.

‘She was staying with me and said she had a pain in her back—an hour later she was in the foetal position. She went into hospital and she never came out again. 

‘It was very hard to see her go through this.’

Dannii said although these dual tragedies were a particularly dark time for her, she managed to pull through with the support of her sister.

Kylie has been very open about the struggles she faced while battling breast cancer and even urged followers in 2018 to donate to UK-based charity Breast Cancer Care. 

Speaking to Karl Stefanovic about her diagnosis on 60 Minutes in 2014, Kylie admitted her cancer journey had taught her to put herself first.

‘Someone had said to me at the time, “You need to be a little bit selfish,”‘ she said.

‘It’s not in my nature to be selfish but now is the time to do that. Let people take care of you. And… that’s what I did.’
