However, sociodemographic factors associated with the development of head and neck (HN) and esophageal second primary malignancies (SPMs) following management of primary breast cancer (BC) have not been well studied. This study examined the association between BC patients’ sociodemographic characteristics and the development of an esophageal or HN SPM.
