Transgender and Gender-Diverse Breast Cancer Screening Pilot

This investigation is a prospective breast cancer screening study open to all transgender and gender-diverse persons (regardless of sex assigned at birth). Using a mixed methods approach, the study will 1) gather prospective quantitative breast imaging data in conjunction with gender-affirming therapy and family cancer history and 2) investigate TGD persons perceptions and experiences in the breast cancer screening program, and 3) identify individual and systems-level barriers to breast cancer screening.
