Key clinical point: Women, particularly post-menopausal women, with diabetes mellitus (DM) faced a higher risk of developing different subtypes of breast cancer (BC).
Major finding: Women with DM had a 20% greater risk of developing BC (risk ratio [RR] 1.20; 95% CI 1.11-1.29), with the risk persisting only in postmenopausal women (RR 1.12; 95% CI 1.07-1.17). The risk of estrogen receptor-negative BC (RR 1.16; 95% CI 1.04-1.30) and triple-negative BC (RR 1.41; 95% CI 1.01-1.96) subtypes increased in patients with DM.
Study details: This meta-analysis of 70 cohort and case-control studies included premenopausal and postmenopausal women with or without DM who developed BC.
