Abstract Introduction - Breast cancer is a public health problem in Algeria, and it is important today to identify the risk groups in order to optimize screening programs. The objective of this study is to discribe the epidemiological profile of breast cancer in West Algeria and to identify its risk factors according to age groups, anthropometric data and lifestyle. Materials and methods - A case-control study (210 cases and 265 witnesses recruited in a general medicine consultation and matched on age and socio-economic level) has been held at the Oncology Department at Oran Hospital. The risk factors addressed in the questionnaire are: early menstruation, parity, oral contraceptives, age at first pregnancy, breastfeeding, late menopause and obesity. Results - The results show that nulliparity is a risk factor for 40 years (OR=14.4, p<0.001) and between 40 and 69 years (OR=12.93, p<0.002). Early menstruation occurs in risk in 40-69 years (OR=5.44, p=0.001). In women over 70 years old, obesity appears to be a risk factor (OR=1.48, p<0.001). The association of cancer and oral contraceptives has not been found in this series. Conclusion - Early menarche, nulliparity and obesity are the main risk factors for breast cancer in women in Western Algeria. Its prevention lies in the action on the modifiable risk factors such as obesity. Among women under 40 years of age, it is recommended to individualize screening by systematic genetic testing.
