Retired NBA superstar Kareem Abdul-Jabbar announced this morning that he has been diagnosed with chronic myeloid leukemia, a disease he's been treating since December 2008. Not only does he hold the NBA's record for all-time leading scorer, he's also won five championships with the Los Angeles Lakers — the team that he is currently coaching. "Having lost one of my closest friends to a different, highly aggressive form of leukemia, I knew how serious my diagnosis was. My own life expectancy became a question mark," says Kareem. But the good news is that with treatment, the father of five is expected to live a long and active life.
