Mammographic Breast Density and Other Factors Associated with Breast Cancer in the City of Ouagadougou (Burkina Faso)

: Objectives: to study the categorization of breast density in mammography and factors associated with breast cancer in women of the city of Ouagadougou. Materials and Methods. It was a descriptive cross-sectional study. The sample consisted of mammography reports. The variables analyzed were socio-demographic, anamnestic and radiological data. Breast density was categorized according to the 5th edition of the American College of Radiology (ACR) Breast Imaging Report And Data System (BIRADS), as well as the results of the mammo ultrasound scans, and then with classification into dense breasts and sparsely dense breasts. We compared two groups (< 40 years and 40 years) based on age, parity, estrogen and mammography results based on breast density. The analyses were carried out using the chi-square test. The significance threshold was p < 0.05. Results. One thousand two hundred and thirty-six mammography reports were analyzed out of a total of 1423 mammograms completed during the study period. The average age of patients was 46.7 years with extremes of 20 and 82 years. Breast density was significantly associated with age, parity greater than four, menopause, normal results and benign breast abnormalities. There was no significant association noted between breast density, malignant lesions, and oral contraception. Conclusion. The breasts of women in the city of Ouagadougou were generally sparse. Breast density in mammography was inversely associated with age, parity greater than four, absence of visible abnormalities or presence of benign abnormalities in mammography and breast ultrasound.
