How this guidance was developed
This recommendation was adopted from the ESO-ESMO 2017 guidelines for breast cancer in young women (Europe), and which remained unchanged in the 2020 updated guidelines. The source recommendation is based on a non-systematic review of the evidence (date was not reported) discussed by the source guideline authors in November 2016 and October 2018 and graded ‘strong’ (using ACCP/Adapted Infectious Diseases Society of America-United States Public Health Service Grading System methods). The source recommendation was adapted to include 'radiation therapy' as a risk factor and minor stylistic changes were made.
