An observational cohort study led by Dr. Carolyn Taylor from the University of Oxford in the U.K. showed that mortality rates for women diagnosed with early breast cancer in England decreased from a 5-year mortality risk of 14% in the 1990s to 5% in 2010-2015.
The researchers analyzed data from 512,447 women. The study included data from the England National Cancer Registration and Analysis Service between January 1993 and December 2015, with a follow-up until December 2020.
The study’s results might also help providers identify prognostic risk factors for women diagnosed with early breast cancer.
The study was published in BMJ.
