Introduction:
Epidemiologic studies on the relationship between breast cancer risk and maternal age at the time of the last birth produced mixed results. We conducted this case control-retrospective analysis to unbiasedly evaluate the association between maternal age at the last birth and the risk of breast cancer.

Material and Methods:
342 women who visited two breast clinics in Greece and gave birth to live infants were examined in our case-control retrospective research. Women without the disease were included in the control group, while those with breast cancer were included in the case group. In addition to digital bilateral mammography being conducted on those who were older than 40 years old, all women got a clinical evaluation that included a breast ultrasound.

Results:
With a p-value of 0.474, the Mann-Whitney test found no statistically significant difference between the two groups of women's distributions of maternal age at the birth of their last child and their risk of developing breast cancer.

Conclusions:
Our study found no statistically significant link between breast cancer and the mother's age at her last delivery. Further studies with a more significant number of patients are mandatory in order to confirm this result.
