In a well-conducted retrospective cohort study, Lipscombe and colleagues1 found that women with diabetes had roughly two-thirds the odds of having a mammogram as women without diabetes. The investigators were able to adjust for women's age, region of residence, income, number of visits, specialty care, and the presence of unstable chronic disease; of note, this Canadian cohort was fully insured for mammography. They conclude that diabetes care may “compete” with cancer screening.
