Association of changes in cancer therapy over 3 decades with risk of subsequent breast cancer among female childhood cancer

JAMA Network

About The Study: Invasive breast cancer rates in childhood cancer survivors have declined with time, especially in those younger than age 40. This appears largely associated with the reduced use of chest radiation therapy, but was tempered by concurrent changes in other therapies, according to the results of this study of 11,550 female survivors of childhood cancer diagnosed between 1970 and 1999.

Authors: Tara O. Henderson, M.D., M.P.H., of the University of Chicago Comer Children's Hospital in Chicago, is the corresponding author.
