Background: Estrogen receptor and progesterone receptor positivity and c-erbB2 gene expression levels are important in determining breast cancer development and aggression. Although the importance of hormonal factors in tumor cell proliferation, migration and differentiation is increasing, it needs more evidence. The effect of BC surgery timing during the menstrual cycle on prognosis remains controversial. In order to clarify this hypothesis, we aimed to determine the importance of adjusting the timing of surgery according to the menstrual cycle by examining the relationship between estrogen receptor, progesterone receptor, c-erbB2 gene and the menstrual cycle phase in patients with premenopausal breast cancer.
