WASHINGTON — A biopsy of a small patch of skin removed from Republican Sen. John McCain's right cheek showed no evidence of skin cancer, doctors said Tuesday.
"No further treatment is necessary," Michael Yardley, a spokesman for the Mayo Clinic in Scottsdale, Ariz., said in a statement released through McCain's presidential campaign.
The GOP nominee-in-waiting had the skin removed Monday as a precaution during a regular checkup with his dermatologist near Phoenix.
The Arizona senator, who suffered severe sun damage from his 5 1/2 years in Vietnamese prison camps, gets an in-depth skin cancer check every few months because of a medical history of dangerous melanomas. He has survived three bouts of melanoma that included four lesions.
