In a recent New York Times article, physician-author Siddhartha Mukherjee wrote about a clinical trial that he characterized as “beautiful,” for potentially illuminating a surprising connection between heart disease and cancer. Mukherjee is a justifiably acclaimed writer, who publishes regularly in The New Yorker and The New York Times, and who won a Pulitzer for his bestselling book The Emperor of All Maladies. But I wonder whether the demands of popular writing have caused him to hype a treatment that, while promising, is far from proven.
