A top cancer surgeon at Columbia University is under scrutiny after one of his research papers was retracted for containing suspect data. Twenty-six other studies by Dr. Sam S. Yoon, who conducted his research at the Memorial Sloan Kettering Cancer Center, have been flagged as suspicious by a British scientific sleuth called Sholto David. David raised the alarm after spotting the same images across different articles that described wholly different experiments. He has also found duplications and manipulated data in papers published by researchers at the Dana-Farber Cancer Institute in Boston that have since been retracted. 

This news shocked me: leading scientists at some of the most respected research centers in the world, working on the very important and well-funded fight against cancer are. . . making stuff up. That seems bad. Really bad. And it poses a lot of unsettling questions, like whether we can really trust medical research at all. But maybe I am missing something. In search of reassurance, I called up an expert: oncologist, UCSF professor, the author of more than 500 academic papers, and Free Press contributor Vinay Prasad. 

Here’s an edited version of our conversation. (Spoiler alert: I was not reassured.)
