Background: Breast cancer is cancer that forms in the cells of the breasts. Breast can­cer starts when cells in the breast begin to grow out of control. The exact cause of breast cancer has not been established, but there are risk factors that may play a role. This study aimed to analyze factors associated with breast cancer risk among women in rep­­ro­ductive age at Pirngadi Hospital, Medan, North Sumatera.

Subjects and Method: This was case control study carried out at Dr. Pirngadi Me­dan, North Sumatera.  A total of 84 women aged 15-49 years who had breast cancer was selected for this study. The dependent variable was breast cancer risk. The inde­pen­dent variables were family history, menarche, breastfeeding history, and history of breast lump. Data on breast cancer were obtained from medical record. The other data were collected by questionnaire. The data were analyzed using multiple logistic re­gress­ion.

Results:  The risk of breast cancer increased with early menarche (OR= 8.46; 95% CI= 2.34 to 30.64), absence of breastfeeding history (OR= 8.46; 95% CI= 2.19 to 32.70), absence of breast lump history (OR=7.12; 95% CI= 1.99 to 25.48), and family history (OR= 4.93; 95% CI= 1.33 to 18.28).
