Objective: Determining the fact if the timing of mastectomy during the menstrual cycle influences the prognosis of premenopausal women with breast cancer. Methods: 67 cases of breast cancer women with regular menstruation were reviewed and analyzed retrospectively by medical statistics in terms of 5-year overall survival, 5-year relapse-free survival and 5-year local-regional relapse survival. Results: Even though the 5-year overall survival and 5-year local-regional relapse survival were not different statistically, timing of operation did have a tendency to influence outcome. Meanwhile, estrogen receptor played the most important role in influencing the above-mentioned aspects in comparison with other factors. Conclusion: We believe that operation during the last menstrual period might have influence on long-term survival of premenopausal breast cancer patients, but prospective studies are needed.
