Breast cancer is the most common type of cancer, with more than 2.2 million cases in 2020. High breast density is a risk factor for breast cancer because malignant lesions are hidden in the dense breast tissue avoiding its early detection. The use of mammography as screening allows the systematic measurement of breast density by manual and computer-assisted methods, classifying it into high and low density. Alcohol consumption and high breast density are factors that increase the risk of breast cancer (BC), but a direct relationship has not yet been established, the measurement of mammographic density was performed with the help of the computer tool (DM -Scan) in 1000 women between the ages of 50 and 69 who attended screening mammography in 2018 and 2019 at the EPS Sanitas / Clínica Colsanitas SA care centers in the city of Bogotá, logistic regression was used. to measure the association between alcohol consumption and mammographic density. Alcohol consumption was not related to higher breast density (95% CI).
