Hollywood 'Stands Up to Cancer'

Stars are pitching in to fight cancer -- and "Extra" is joining the cause! "Extra" gets personal with Hollywood bigwigs taking part in the "Stand Up to Cancer" telethon, including breast cancer survivor Melissa Etheridge, plus Tobey Maguire's wife Jen Meyer -- who is donating proceeds from necklaces she designed. Even Homer Simpson is helping out!

Join the fight when "Stand Up to Cancer" airs September 5.
