Christie Brinkley's scar from skin cancer removal surgery is "barely noticeable".

The 70-year-old model was diagnosed with basal cell carcinoma on her face earlier this year after she accompanied her daughter Alexa Ray Joel, 38, to a dermatologist appointment and asked the doctor to check out a spot that was worrying her. She subsequently had the cancerous cells removed and she is thrilled to have been left with a scar that's barely visible.

During an appearance on the 'TODAY' show, Christie explained: " They got a great surgeon, a great plastic surgeon to stitch it up and they took care of it and luckily, my hair grows in that direction, but the scar is barely noticeable."

She also spoke about how her diagnosis came about during her daughter's skin appointment. Christie explained: "I was in the room, and he had this little magnifying glass out, and he's looking at a couple of things that she was worried about.

"I thought, 'There is that little spot right on the side of my head right here ... Should I say anything? It's not my appointment.'

"Then right at the very end, as he was putting away his little thing, I said, 'Before you put that away, do you think you could just look at this?'

"He looked and he goes, 'We've got to do a biopsy immediately. This is something.' Then the biopsy came back (as) cancer'."

After undergoing surgery, Christie went public with her cancer news and urged others to be extra vigilant with sun protection and skin check-ups.

In a post on Instagram, she wrote: "The good news for me is we caught the basal cell Carcinoma early. And I had great Doctors that removed the cancer and stitched me up to perfection like an haute couture Dior.

"The good news for you is that all of this can be avoided by being diligent with your sun protection! I got serious a bit late so now for this ole mermaid/gardener, I’ll be slathering on my SPF 30, reapplying as needed, wearing long sleeves and a wide brim hat. And doing regular total body check ups ... that is a MUST!"
