Developments on the Beastie Boys’ summer plans and new dates from Bruce Springsteen top the daily tour recap for July 20, as compiled by TicketNews.

Original Beastie Boys member Adam “MCA” Yauch announced today that he has been diagnosed with cancer. The tumor is on his salivary glands and a bit of his lymph nodes. Though he is expected to recover after surgery and further treatement, and his vocal chords will not be affected, Yauch announced that the Beasties’ tour dates have been cancelled for the summer and the release of their newest album has been delayed indefinitely.

In other concert and touring news, Bruce Springsteen & The E Street Band have extended their U.S. tour plans for this year to include more than 10 additional cities and a total of 25 concerts. Another American music icon, Brian Wilson, will also tour the U.S. this fall for a 17-city tour that is currently booked from late October through early December. Finally, public ticket sales open tomorrow for the 2009 Bumbershoot Festival, which takes place September 5-7 at the Seattle Center in Seattle, WA.

Those are the complete reports for this Monday, but read on for some of the day’s other itinerary updates in brief. And, as always, check back tomorrow for more of the latest concert and ticket industry news from TicketNews.
