Background: Screening mammography is underutilised in our environment, and this is a major factor in late presentation of breast cancer. Our objective was to evaluate the importance of screening mammography in a population of Nigerian women and to describe the pattern of early breast cancer.
Methods: A prospective study of 305 women that presented for screening mammography following a health campaign on breast cancer awareness.
Results: Negative Mammogram (BI-RADS 1) comprised 77.37%. Benign mammogram (BI-RADS 2) was 13.77%. BI-RADS 3 and 4 comprised 1.30%; inconclusive mammogram (BI-RADS 0) was 7.54%. Breast mass is the most common lesion, bilateral in 6 and unilateral in 19 or in combination with other pathologies in 5 women. Calcifications alone were present in 10 women; while asymmetric densities without other pathologies were noted in 7 women.
Conclusion: The mammographic appearance of early breast cancer in Nigeria women is similar to findings in developed nations. The provision of screening facility will definitely reduce the scourge of late presentation and resultant deaths from breast cancer in our environment.
Keywords: Breast Neoplasm, mammograms, mass screening, BI-RADS.
Résumé
Le dépistage mammographique est moins utilisé dans notre environnement, et ceci est un facteur majeur pendant la présentation tardive du cancer du sein. Notre objective était d’évaluer l’importance du dépistage mammographique chez une population des femmes nigériane et de décrire la fréquence du cancer du sein précoce. Cette étude prospective sur 305 femmes qui venaient pour le dépistage mammo-graphique suivi d’une champagne de sensibilisation sur le cancer du sein. Les Mammogrammes négatives (BI-RADS 1) comprenaient 77.37%.les cas bénignes (BI-RADS 2) étaient de 13.77%. BI-RADS 3 et 4 comprenaient 1.30%; Mammogrammes inclusives (BI-RADS 0) chez 7.54%. La masse au sein était la plus commune avec une lésion bilatérale chez 6 et unilatérale chez 19 ou en commination avec autres pathologies chez 5 femmes. Seules Les calcifications étaient retrouvées chez 10 femmes; tandis que les densités asymétriques sans pathologies
étaient notées chez 7 femmes. En conclusion, l’apparence de la mammographique dans le cancer du sein précoce chez les femmes au Nigeria est semblable aux données dans les pays développés. La provision des facilités de dépistage réduira définitivement le taux de présentation tardive et de décès du cancer du sein dans notre environnement.
