The Relationship Between Mammographic Density and Factors Affecting Breast Cancer Risk

Abstract

Objectives: Although the relationship between breast cancer (BC) risk factors and mammographic density (MD) patterns is not clear, high MD is well known as an independent risk factor for BC. Thus, the aim of this study was to examine the association be- tween MD and BC risk factors in BC patients and find a correlation between MD and tumor characteristics in BC patients. Methods: Our data included 242 patients with BC. Furthermore, the MD (type I - 75%) was categorized according to percentile density, and the various types of MD were compared using risk factors for BC and tumor characteristics of patients. Results: The results of this study indicated that younger age, pre-menopausal status, younger menarche age, nulliparity, low body mass index, and smoking significantly increase the percentage of MD (p
