Our study assessed the association between breast density, BMI and the breast cancer risk among women aged \u226575\u2009years. We included women who underwent breast cancer screening between 2009 and 2014 and were followed up until 2020. Breast density was measured using Breast Imaging Reporting and Data System. BMI was classified into three groups: &lt;23, 23 to &lt;25 and \u226525. Cox proportional hazards models were used to estimate the association of breast density and BMI with breast cancer risk. In 483\u2009564 women, 1885 developed breast cancer. The 5\u2010year incidence increased with an increase in breast density and BMI. Increase in breast density was associated with an increased breast cancer risk in all BMI categories: among women with BMI &lt;23, those with heterogeneous\/extreme density had a 2.98\u2010fold (95% CI: 2.23\u20103.80) increased risk of breast cancer compared to those with entirely fatty breasts. An increase in BMI was associated with increased breast cancer risk in women with the same breast density in all density categories. When the combined associations of breast density and BMI on the risk of breast cancer were considered, women with a BMI \u226525 and heterogeneous\/extreme breast density had a 5.35\u2010fold (95% CI: 4.26\u20106.72) increased risk of breast cancer compared to women with a BMI &lt;23 and fatty breasts. Women aged \u226575\u2009years, with dense breasts, regardless of BMI status, might benefit from a tailored screening strategy for early detection of breast cancer.<\/jats:p>","DOI":"10.1002\/ijc.34038","type":"journal-article","created":{"date-parts":[[2022,4,23]],"date-time":"2022-04-23T04:33:30Z","timestamp":1650688410000},"page":"869-877","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Mammographic
