McCain addressed concerns about his age and past health issues, stating in 2005 that his health was "excellent". He had been treated for melanoma and an operation in 2000 for that condition left a noticeable mark on the left side of his face. McCain's prognosis appeared favorable, according to independent experts, especially because he had already survived without a recurrence for more than seven years. In May 2008, McCain's campaign briefly let the press review his medical records, and he was described as appearing cancer-free, having a strong heart, and in general being in good health.
