Background: Women with metastatic breast cancer face unique challenges as they cope with life-limiting prognoses and arduous treatments. However, the vast majority of research has focused on optimizing quality of life in women with early-stage, non-metastatic breast cancer and little is known about supportive care needs among women living with metastatic cancer. As part of a larger project that sought to inform the development of a psychosocial intervention, the aim of this study was to characterize supportive care needs among women with metastatic breast cancer and elucidate challenges unique to living with a life-limiting prognosis.

While affect is linked to a number of diabetes outcomes, the specific role of positive affect (PA) in HbA1c remains unclear.

Nevertheless, most research has paradoxically focused on optimizing quality of life in women with early-stage, non-metastatic breast cancer.
