University of Chicago Medicine has received a $75 million donation from the AbbVie Foundation to help it build its massive new cancer hospital on the city's South Side. The money will go toward construction of UChicago Medicine's new freestanding hospital — a 575,000-square-foot project that is expected to cost $815 million. The building will be named the AbbVie Foundation Cancer Pavilion, and is slated to open in 2027.
