Breast screening for people on hormone therapy

Official title: Understanding Breast Cancer Risk and Screening in Individuals on Hormone Therapy Through a Pilot Breast Cancer Screening Program

Run by Medical College of Wisconsin · NCT06383026 · Data updated 2026-11-12

This pilot will see if combining mammography and breast ultrasound with surveys and interviews improves screening for people on hormone therapy aged mostly 40–75 (and some 30–39 with family history).

Is this trial a fit for you?

Likely a good fit

Ideal candidates are people aged 40–75 on hormone therapy (males with ≥9 months of estrogen and/or progesterone, females with any history of testosterone) and select 30–39-year-olds with a first- or second-degree family history of breast cancer who can consent in English.

Probably not a fit

People not on hormone therapy, those who have had a complete mastectomy, or individuals who cannot participate in English or travel to the site are unlikely to benefit from this pilot.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This prospective mixed-methods pilot will collect quantitative breast imaging (mammography and ultrasound) alongside medication and family history information in people taking hormone therapy. Participants will also complete surveys and may join interviews or focus groups to capture perceptions and experiences with screening. The study aims to identify individual- and system-level barriers to timely screening and to compare imaging findings in the context of hormone exposures. Breast radiology faculty who read both automated breast ultrasound and mammography at the Medical College of Wisconsin will be involved in image interpretation.

Why it matters

Potential benefit: If successful, the project could lead to clearer, more tailored screening guidance and earlier detection for people on hormone therapy.

How similar studies have gone: Prior studies have shown hormone therapy can change breast density and affect imaging performance and some centers have trialed ultrasound as an adjunct, but comprehensive mixed-methods pilots focused specifically on people on hormone therapy remain limited.

4. Individuals who meet criteria for above eligibility and are ≥30-39 years of age with a 1st or 2nd degree family member with breast cancer.
5. Ability to speak, read, and write in English.
6. Ability to understand a written informed consent document, and the willingness to sign it.

Inclusion Criteria for Breast Radiology Faculty:

1. Board-certified radiologist that specializes in breast imaging and are an actively employed faculty member at Froedtert \& the Medical College of Wisconsin (main campus location).
2. Part of the breast radiology faculty who read both ABUS and MMG of the study participants.
3. Ability to speak, read, and write in English.

Exclusion Criteria for Individuals on Hormone Therapy

1. Females who have undergone or planned to undergo a complete mastectomy.
2. Females who are post-menopausal on estrogen +/- progesterone hormone therapy since it is a well-established risk for breast cancer).
3. A personal history of breast cancer or a known pathogenic gene mutation that increases the risk of breast cancer development (e.g., BRCA1/2, etc.) given that well-defined surveillance and screening recommendations exist for these persons.

Exclusion Criteria for Breast Radiology Faculty
