ABSTRACT
Introduction:
To investigate a possible association between breastfeeding and breast cancer risk in Greek women.
Material and Methods:
Totally, 391 women participated in our case-control retrospective study. 238 women with breast cancer were included in the case group, while in the control group 153 women without breast cancer who were enrolled in two breast clinics in Greece. All women were examined clinically and with breast ultrasound, while those older than 40 years old also with bilateral digital mammography.
Results:
The x2 (chi-square) test found a statistically significant reverse correlation between breast cancer and breastfeeding ≥12 months (cumulative) (p = 0.001). It was observed that the percentages of patients who breastfed ≥12 months were lower than those of healthy women.
Conclusions:
Breastfeeding and particularly the cumulative period of ≥12 months is related to the maximum of protection from breast cancer.
