Daniel Hayes is racing to record the stories of oncology’s greats.

In May 2018, Hayes, the Stuart B. Padnos Professor of Breast Cancer Research and professor of internal medicine at University Michigan Rogel Cancer Center, started to conduct interviews with friends, mentors, and colleagues.

The podcasts are published in the Journal of Clinical Oncology’s Cancer Stories.

“I try to make it—if you could be in a cab for 20 minutes with one of your heroes, like we do if you like sports, or medicine, or literature, or music, and just say— ‘How did you do this? What made you think you could even do this sort of thing?’” Hayes said to The Cancer Letter.

Hayes’s podcast, a program of the American Society of Clinical Oncology, is a part of a larger effort to commemorate the history of the cancer field in 2021.
