Longtime ESPN college basketball analyst Dick Vitale says he has been diagnosed with cancer for a third time. Vitale tweeted Wednesday that he had surgery in Boston this week, and tests revealed that he has vocal cord cancer. He said he will undergo six weeks of radiation treatments. He says he will fight to be ready to call games when the college basketball season begins this fall. The 84-year-old has previously been treated for melanoma and lymphoma. Vitale has been with ESPN since 1979.
