Development Of A Blood Test To Improve The Performance Of Breast Cancer Screening

Participants with dense breast tissue will get a mammogram and MRI

State-of-the-art full-field digital mammography (FFDM) and or digital breast tomosynthesis (DBT) comprising both raw and post-processed images as well as ultrasound and MRI images from the initial screening study will be collected and sent to the MSKCC Breast Radiology Department.

Participants will donate approximately 60ml of peripheral blood. Mononuclear cells from peripheral blood will be used to extract germline DNA. Germline genomic testing will be employed as a matched control for tumor sequencing and for germline breast cancer susceptibility testing.

Tissue specimens from the biopsy of the BI-RADS 4 mammographic lesion and (among women undergoing surgical excision) the surgical specimen(s) will be subjected to genomic profiling at GRAIL, Inc. or MSKCC. The tumor specimens from the participants diagnosed with cancer during the follow-up period will also undergo molecular profiling.

Participants will be asked to complete a questionnaire that covers the topics of breast health, general health and lifestyle, genetic testing, personal, and family history of cancer.
