Both candidates make stop at doctor

The candidates' health is back in the spotlight in the presidential race.

John McCain's campaign said this afternoon that he had a small mole removed from his head to be tested. It said it does not appear to be anything serious, but the presumptive Republican nominee has a history of skin cancer. In May, he released a raft of medical records and declared that he is cancer-free.

UPDATE: His campaign issued a statement from the Mayo Clinic: "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."

McCain, himself, made light of the mole. After touring oil fields in Bakersfield, Calif., he told reporters this afternoon that skin cancer is "one of the most preventable occurrences."

"That's the end of my lecture from the American Dermatology Association," he said, wearing a Navy ballcap.

Democrat Barack Obama, meanwhile, saw a doctor in Chicago on Sunday night for a sore hip. A spokesman blamed playing basketball on the campaign trail the past few weeks. As he left the hospital, Obama told reporters: "I had small X-rays. Everything's OK. I think I'm going to be good in about a week."
