Effect of persistent menopausal symptoms on the wellbeing of Japanese breast cancer survivors

While more women with breast cancer survive because of advances in cancer treatment including hormonal therapy, they are at a risk of menopausal symptoms, which can threaten their psychological wellbeing. We examined the effect of menopausal symptoms on women's psychological wellbeing during three different phases of breast cancer: short‐term (0–1 years since diagnosis), medium‐term (2–5 years), and long‐term (more than 5 years). In this cross‐sectional study, 425 survivors treated with hormonal therapy were recruited from a convenience sample in Japan and completed an anonymous self‐administered questionnaire. Multiple regression analysis revealed that menopausal symptoms significantly contributed to psychological wellbeing in all phases. In long‐term survivors, menopausal symptoms were significantly milder; however, the negative effect was prolonged. One in three to four survivors was suspected to have poor psychological wellbeing, irrespective of time. Although the effect of menopausal symptoms on psychological wellbeing has been described in short‐term survivors, little is known about the long‐term effect. This study examines the effect of menopausal symptoms on psychological wellbeing, thereby providing useful information regarding long‐term quality of life.
