Purpose: Even if favorable cosmetic outcomes are obtained shortly after breast conserving surgery (BCS), cosmetic changes may occur up to several years after BCS. In the present study, we evaluated cosmetic changes while focusing on changes in the nipple position after BCS.Methods: We examined the long-term course of changes in the nipple position overtime after BCS using the proportion of the distance between the sternal notch and nipple (PDSN) in 196 patients. We also evaluated risk factors for long-term nipple position changes.Results: The median follow-up period was 9.9 years. Nipple position changes occurred within eight years after BCS and seemed to plateau beyond that point. The body mass index (BMI), breast size, proportion of excision volume and axillary treatment were significantly associated with the nipple position changes within one to five years after BCS. The BMI, breast size, axillary treatment, chemotherapy and hormonal therapy were significantly associated with the nipple position changes within five to eight years after BCS.Conclusions: After BCS, the nipple position changes occur within about eight years. Obesity, large breast size, large excision volume, axillary treatment, chemotherapy and hormone therapy were factors that affected the treated breast shrinkage and increase in the left-right difference after BCS.
