McCain urged people to stay out of the sun and wear sunscreen, particularly during the summer.
"If you ever have any slight discoloration please go to your dermatologist or your doctor and get it checked out as soon as possible," he said.
Asked if his doctor was confident the problem was nothing serious, McCain replied, "Sure, sure."
The Arizona senator, who suffered severe sun damage from his 5½ years in Vietnamese prison camps, gets an in-depth skin cancer check every few months because of a medical history of dangerous melanomas.
