Breast cancer is the most common cancer among women worldwide with more than 1.1 million newly diagnosed every year. Over the past years, much clinical effort has been directed to the treatment of breast cancer in order to improve survival. Moreover, breast cancer affects women's identities, personality, social life, and, above all, future choices. Quality of life has become a well-accepted outcome measure for cancer patients and an integral part of cancer patient management. Much of this attention, however, is on the quality of life in young women, with insufficient attention directed to older patients, forgetting how life expectancy has increased and how it is particularly important to not only increase the years of life, but also increase the share of life spent in good health. Thus, it is crucial to consider the individual woman living with breast cancer and the treatment and importance of qualitative methods for generating patient reported outcome measures (PROMs) and patient reported experience measures (PREMs) for elderly women with breast cancer.

The aim of this special issue is to provide new findings regarding PROMs and PREMs in elderly woman affected by breast cancer and to stimulate clinicians (surgeons, oncologists, senologists, and radiotherapists) and those who manage and assess elderly women with breast cancer, to consider quality of life before starting any treatment, and how this treatment can impact the patient’s future quality of life. Starting from these bases we invite authors to contribute original research articles, as well as review articles, to this special issue. We are particularly interested in articles that offer an overview of the existing concepts, novel findings, and challenges in this area and their potential utility in personalized patient treatment.

Potential topics include but are not limited to the following:
