Introduction: Breast cancer is the most common cancer and the first cause of cancer-related\ndeaths among women in Cameroon. The aim of the study was to investigate\nits risk factors for breast cancer at two University Teaching Hospitals in\nYaound�©. Methodology: A case-control study was conducted for 5 months, from\nFebruary 25th to July 25th 2015, at the Gynecology unit of the Yaound�© Gyneco-Obstetric\nand Pediatric Hospital (YGOPH) and the Medical Oncology unit of the\nYaound�© General Hospital (YGH). One hundred and five patients with breast cancer\n(cases) were compared to 210 women who did not have breast cancer (controls).\nSPSS Version 18.0.0 software was used to analyze the data with a statistical significance\nconsidered at P-value < 0.05. Results: After univariate analysis, risk factors associated\nwith breast cancer were: patient age > 50 years (P < 0.00; OR = 4.16; CI =\n[2.50 - 7.14]); widowhood (P = 0.001; OR = 3.45; CI = [1.7 - 6.9]), monthly income <\n86 US dollars (P = 0.002; OR = 2.19; CI = [1, 31 - 3.65]), primary level of education\n(P = 0.005; OR = 2.11; CI = [1.25 - 3.56]), consumption of red meat > three times per\nweek (P = 0.002; OR = 2.14; CI = [1.33 - 3.45]), palm oil consumption > two times per\nweek (P = 0.001; OR = 2.38; CI = [1.4 - 4.1]). After multivariate analysis, age > 50\nyears (aOR = 41.48; CI = [2.46 - 69.9]) and consumption of red meat > three times\nper week [aOR = 7.33; (1.49 - 36)] were the risk factors considered significant for\nbreast cancer. Conclusion: Age > 50 years and red meat consumption are independent risk factors for breast cancer at the Yaound�© General Hospital and at the\nYaound�© Gyneco-Obstetric and Pediatric Hospital.
