Kylie Minogue is currently enjoying a relaxing holiday in Mykonos, Greece.

And on Thursday, the Australian-born singer, 56, shared a series of snaps from her trip to Instagram including a photo of herself swimming in a black rash vest.

However, some fans questioned why the pop star was going for a dip in the covered up swimwear.

'Why is she swimming with the t-shirt on?' one questioned.

Others suggested Kylie was protecting her skin and 'being careful' after previously battling breast cancer in 2005.

'She's being careful after having cancer,' one wrote, while another explained: 'UV50 top, prevents melanoma.'

'It's not a t-shirt , it's a rash vest which is made purely for the purpose of swimming and blocks 100% of UV rays,' a third wrote.

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.

Speaking to Karl Stefanovic about her diagnosis on 60 Minutes in 2014, Kylie admitted that 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'.'

'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.'
