(Updates with CBS report on records)

By Steve Holland

PHOENIX, May 23 (Reuters) - Republican John McCain is in good health and has had no signs of skin cancer since 2002, CBS television said medical records of the presidential candidate to be released on Friday will show.

CBS said McCain's doctor described him as "considerably younger than his chronological age based on his cardiovascular fitness."

The Arizona senator's health records will show that his blood pressure and weight are healthy and he has occasional bouts of dizziness when he stands suddenly but which tests have shown are not a concern, CBS reported. He takes a common medication for cholesterol control, it said.

McCain is releasing his medical records to try to put to rest lingering questions about his health and ability to handle the rigors of the presidency.

McCain will be 72 in August and the oldest American ever elected to a first presidential term if he wins the November election.

He had major surgery on his face in 2000 for melanoma, a potentially lethal form of skin cancer. The surgery left a noticeable scar and bulge down the left side of his face.

One source of concern about McCain for many Americans is his age, and McCain has sought to address any questions by pursuing a vigorous campaign, but until now has not released detailed information about his health.
