Racial and ethnic disparities in mortality among breast cancer survivors after a second malignancy.

ABSTRACT:

Background

Racial and ethnic differences in survival after a first cancer are well established but have not been examined after a second primary cancer (SPC) despite the increasing incidence among survivors.

Methods

We examined 39 029 female breast cancer survivors who developed an SPC between 2000 and 2014 in the Surveillance, Epidemiology, and End Results 18 database.
