Natalie Barr shocked Sunrise viewers on Tuesday morning by revealing she had recently been diagnosed with skin cancer.

The Channel Seven star, 56, said she visited her dermatologist after discovering a tiny persistent 'pimple' on her nose.

Natalie's doctor used state-of-the-art AI and 'Spectra-Scope' devices to inspect the blemish and found a cancerous lesion.

'I had a pimple on my nose that wouldn't go away, plus I reckon it had been a couple of years since I had a skin check, so I went to the dermatologist,' she said.

'He said it was skin cancer - this tiny little dot on my nose. The good thing is I got it really early, and there's not much treatment.'

Natalie went on to explain the spot is so small she is able to have it removed with two non-invasive treatments.

The TV star's dermatologist used an AI device to detect worrisome changes in her skin when compared to a global database.

He then used a laser-induced plasma device called a Spectra-Scope to detect cancerous cells in the spot, before doing a biopsy to confirm it was skin cancer.

Co-host Matt 'Shirvo' Shirvington asked Natalie: 'When you saw that graph, and it indicated that it was skin cancer, how nervous were you?' 

'You sort of go, "Oh my God". So many Aussies, millions and millions of us, have skin cancer, but it does make you think,' the breakfast show host responded.

Natalie said she hoped it served as a reminder to everyone to get their skin checked regularly.

It comes after Natalie recently revealed she has been too busy to take care of her health and had to set up a workout station at home to keep up with her exercise.

She admitted in June she installed a reformer Pilates bed from the Your Reformer inside her house so she can get sweaty any time she likes. 

'This year hasn't quite gone to plan. (exercise wise). I've been constantly booking classes and then having to cancel because of work/life,' she wrote on Instagram. 

'So I've brought the plan to me. A Pilates reformer in my house! I'm starting slow.'
