SAM Champion opened up live on ABC about his cancer health battle.

As the star returned to work in front of the camera, he’s been left with a facial scar.

But Sam, 63, wanted to let the viewers and his fans know exactly why his face has changed.

He issued a warning for viewers to use sun protection after he revealed that he was previously diagnosed with skin cancer.

The star was welcomed back into the Good Morning America studio with the likes of Michael Strahan, 52.

“We started talking a little about it and so many people were interested in it.

“[So] we thought we’d continue the conversation. There have been so many advancements in sun protection, sunscreen, laser treatments for pre-cancerous areas.

“So I hope one day nobody has to go through surgery to get rid of skin cancer.

“But now we have to keep an eye on our skin, our hands on our skin, be very vigilant, and notice any unusual spots.”

He added, “And if those spots change, then get immediate care.”

The show cut to a pre-recorded segment where the star explained more about his journey.

“Recently I had to step away from the studio to treat some skin cancer.

“It’s not my first bout with the life-threatening disease, but this time I got a biopsy on a spot right under my eye, which turned out to be a basal cell carcinoma.”

The camera then cut to the host as he sat down in a consultation room down with his doctor.

He said, “We came in to do one particular spot.”

The anchor then went onto reveal more about the particular details surrounding his treatment and the road to recovery.

“Dr. Rossi also performed laser treatment using a CO2 laser to remove some of these dark pre-cancerous spots on my face.”
