Female doctors are paid significantly less than their male co-workers, a wage gap that totals at least $2 million over the course of a 40-year career in medicine, according to a new study. 

The study, published Dec. 6 in Health Affairs, used survey data from more than 80,000 physicians throughout the United States, collected between 2014 and 2019. It is the first analysis to quantify the long-term impact of the gender pay gap that exists in medicine, the New York Times reports.
