CHICAGO (AP) - Chicago's skyline is changing colors for a good cause.
Mayor Rahm Emanuel and other officials announced that some of Chicago's most iconic buildings will be lit up purple in support of Pancreatic Cancer Awareness Month in November.
The 15 buildings include such big names as the Willis Tower, Trump Tower, Wrigley Building, Blue Cross/Blue Shield and the AON building. Some other participating buildings are Inland Steel, Northern Trust Bank, Bloomingdale's and the Goodman Theatre building.
The Pancreatic Cancer Action Network says it's grateful the city is helping to build public awareness about the deadly disease.
