The American Society of Clinical Oncology (ASCO) begins its 2024 annual meeting at the cavernous and labyrinthine McCormick Place convention center in Chicago Friday, May 31. It’s one of the world’s largest cancer research conferences and can be daunting to follow.  More than 400 organizations will participate this year, with about 200 sessions ready to convene. The vast majority of the 5,000 abstracts that cover all aspects of cancer treatment have already been released, and they will be scrutinized by the more than 40,000 attendees from around the world.
