Gupta, Sanjay. "Fit to Lead." CNN. Special Investigations Unit. Broadcast 2008 October 11. Note: I have some questions about bias in this source. They claimed that Senator McCain's temple melanoma was the size of a dime and the thickness of a nickel. It was actually larger then a penny (which is larger than a dime) and thicker than a nickel. In addition, they devoted much air time to Senator Obama's smoking history, without once mentioning that Senator McCain smoked two packs of cigarettes per day for about 25 years.
