Senator John McCain has been diagnosed with brain cancer.
He is at home in Arizona now. His office says he is weighing his treatment options and hoping to be able to return to Washington D.C.
McCain, who is 80, was the 2008 Republican nominee for president. He was diagnosed with glioblastoma, one of the most deadly forms of brain cancer. It strikes about 13,000 Americans each year. It's the same type that struck down Massachusetts Senator Ted Kennedy eight years ago.
Dr. David Reardon was involved in the treatment of Senator Kennedy's glioblastoma. He is now clinical director of the Dana-Farber Cancer Institute's Center for Neurooncology.
Reardon spoke with WGBH All Things Considered host Barbara Howard about what glioblastoma is, how he treated Senator Kennedy, and what the prognosis could be for Senator McCain.
