(CNN) - John McCain told CNN’s Larry King Monday that voters should not be concerned about his health, hours after the Arizona senator had a mole-like growth removed from his face.
McCain, who has had four malignant melanomas removed in the past, told reporters earlier in the day his doctor does not believe the latest growth is serious and was removed as a precautionary measure.
In the interview with King, McCain said he now takes precautions from the sun and is not concerned his skin cancer will return.
"Melanoma, if you look at it and be careful it's fine," he said. "I had one serious bout with it and that was frankly due to my own neglect. I let it go and go and go. In fact, I was running for president at the time. I'm not making that mistake again."
Three of McCain's past melanomas — on his left shoulder, left arm and left nasal wall — were limited to the top skin layer and were not invasive. They were removed in 1993, 2000 and 2002, and all were declared Stage 0, of little long-term concern.
But a fourth melanoma proved to be invasive and was removed from his left lower temple in 2000.
McCain also said he gets a routine skin checkup every three months, and his doctor often removes small patches of skin to ensure he remains cancer free.
"We do it quite frequently for those of us that were young and had great exposure to the sun," he said. "As you know my dad was in the Navy and we lived in places where I was at the beach a lot, and I'm paying the price for that."
McCain's comments also came shortly after the Mayo clinic issued a statement on the procedure.
"This morning, as part of his commitment to monitor his dermatological health on a regular basis, Senator John McCain visited the Mayo Clinic in Scottsdale, Arizona, for a routine examination. As a precaution, a biopsy was ordered of a very small area on Senator McCain's right cheek. This is a routine minor procedure," said Michael Yardley, Chair of Public Affairs at the Mayo Clinic/
