"Don't let our kids make the same mistakes." Jackie O's powerful skin cancer warning.

Radio host Jackie O Henderson has shared that a large abrasion on her forehead is from having a skin cancer removed.

The abrasion first caused concern when Jackie O was photographed with it following a holiday in Port Stephens.

Following speculation, the 43-year-old shared an image on Instagram to confirm it was skin cancer.

Posing with her with daughter Kitty, Jackie captioned the photo: “Don’t let our kids make the same mistakes. Slip, slop, slap.”

Back in September, Jackie spoke about getting the cancer removed with KIIS FM co-host Kyle Sandilands.

"I'm going to have a big scar on my forehead - I'm going to have stitches," she said. "Don't call me 'Scarface'. Don't tease me about it, but it's happening soon."

She said she has skin cancer checks every six months, to which Kyle asked if she'd ever had skin cancer before.

She replied that she "had heaps cut out".

"But they're always in places you don't see. They're harmless ones, they're not the deadly ones. I had one just below the collarbone and that took eight months [to heal]. It was quite a red scar."

Discusses the skin cancer on her forehead, Jackie said it wasn't visible because it's pale pink.

"A lot of skin cancers you don't see, you don't think it's a skin cancer, you just think it's a blemish or something."

While Jackie is now sporting a sore-looking abrasion, it's much better than the alternative.

She has previously advised for listeners - and Kyle - to have their skin checked regularly and is now advocating for parents to ensure they make sure their children are sunsmart.

According to the Australian Institute of Health and Welfare, in 2014 there were over 358,000 incidents (number of paid Medicare services) of non-melanoma skin cancers in women in Australia and more than 5400 cases of women diagnosed with melanoma. Among women it is expected that melanoma will continue to increase to about 45 new cases diagnosed per 100,000 women in 2020, equating to approximately 6790 cases per year.
