GRAIL is using high-intensity sequencing of circulating cell-free nucleic acids (cfNAs) to develop blood tests to detect cancer early. The purpose of this study is to train and validate an assay to detect invasive breast cancer in patients undergoing mammography.

The purpose of this study is to assess the effect of acculturation, socio-economic status (SES) and place of residence (urban vs. rural) on the level of participation in breast cancer screening programs and on the breast cancer knowledge and beliefs among Asian American women in Olmsted and surrounding counties.

The purpose of this study is to help women in their late 30s and in their 40s, make decisions regarding breast cancer screening that align with each women’s values and preferences. 

The purpose of this study is to understand how women of color from diverse racial and ethnic backgrounds conceptualize their current and lifetime risk for breast cancer (BC) and to identify which risk factors most resonate with perceptions of BC risk.

The purpose of this research is to optimize and evaluate the efficacy of a hybrid imaging and quantitative viscoelasticity measurement tool for breast cancer detection and monitoring.

The goal of this research is to identify risk profiles of women (with particular emphasis on Hispanic women) for breast cancer based on family history, breast density and other factors known to impact risk such as age, weight, age at menarche, age at birth of first child, etc.

The aim of this study is to use the combine clinical risk assessment models that are already used in routine clinical practice with information derived from polygenic risk score (PRS) testing in women of racial minorities to see if this can improve adherence to recommended breast cancer screening and prevention strategies.

The goal of this project is to develop an AI system for early cancer detection on routine screening tomosynthesis mammograms. There will be significant impact on clinical practices if a mammography AI tool can be built. Such a tool will improve efficiency and decrease false positives and false negatives in practice. 

This protocol captures the details for the reader study involving Aidoc, ScreenPoint, and iCAD. Mayo Clinic Breast Imaging Radiologists will evaluate the software tools that both ScreenPoint  and iCAD have developed for assisting in reading tomosynthesis scans. Aidoc is facilitating this study by providing their user ...

This study proposes to combine data from six large existing epidemiology studies to examine the association of MD and clinical risk factors with breast cancer subtypes. 

The purpose of this study is to gather qualitative information about patient comfort during MBI examinations. The primary aim is to assess patient comfort during MBI, relative to comfort during a mammogram. We also wish to identify factors that contribute to discomfort and patients’ willingness to have MBI in the future.

The purpose of this study is to to bring molecular risk prediction for breast cancer into the clinical arena through: the establishment of a large tissue repository from a retrospective cohort of women with benign breast disease with complete and long-term clinical follow-up to identify those who developed breast cancer (cases) and those who did not (controls); the application of potential biomarkers of risk to this archival tissue set; and, the discovery of new, potentially relevant biomarkers of risk in fresh and frozen specimens of benign breast disease. 

Increased mammographic density is recognized as an important risk factor for developing breast cancer, however, the underlying mechanism explaining this relationship is unclear. The investigators hypothesize that Molecular Breast Imaging (MBI) can more accurately distinguish dense tissue on mammography which is at high risk from dense tissue at low risk by indicating cellular activity in dense tissue as radiotracer uptake (functional density) in the breast. In this pilot study, the investigators want to compare the histological characteristics of breast tissue in patients with who have similar density on mammography but different levels of functional density on MBI.

The investigators hypothesize that knowledge of the functional behavior of areas of mammographic density will enable more specific identification of dense tissue at-risk for breast cancer, ultimately providing predictive information on an individual's risk of developing breast cancer.

The purpose of this research study is to understand the views and experiences of Non-Hispanic Black women with a diagnosis or who support a family member with breast or ovarian cancer. We also want to know participant thoughts on genetic testing for cancer risk and research participation.

This is a qualitative interview study. Study participation involved talking on the phone or videoconference (e.g., Zoom) for about 1 - 1 1/2 hours with a researcher.

The primary aim of this study is to determine if the addition of an individual polygenic risk score (PRS) in addition to the Breast Cancer Risk Assessment Tool (BCRAT) or Tyrer-Cuzick (IBIS) score will aid women at risk of breast cancer in making a decision to take (or not take) medications to prevent breast cancer.

The no show rate for mammography screening is high among Navajo women. One barrier to preventive screening is a lack of cancer literacy including low knowledge and cultural attitudes (e.g., fatalism) about screening. The investigators will examine the potential feasibility and acceptability of a cancer literacy intervention for families of Navajo women who have no showed for three consecutive times to mammography screening who have never or rarely been screened in the past.

In this research study, the investigators are testing a new type of breast camera, called Molecular Breast Imaging, to see if it can find tumors in the subject's breast.

Estrogen can cause the growth of breast cancer cells. Hormone therapy using tamoxifen citrate may fight breast cancer by blocking the use of estrogen by the tumor cells

This phase IIb trial studies how well low-dose tamoxifen citrate works in reducing breast cancer risk in radiation-induced cancer survivors.

The primary aim of this study is to determine if the addition of an individual polygenic risk score (PRS), in addition to the standard National Cancer Institute's Breast Cancer Risk Assessment Tool (BCRAT) or Tyrer-Cuzick (IBIS) score, will aid women at risk of breast cancer in making a decision to take (or not take) medications to prevent breast cancer.

The purpose of this study is to evaluate a low-cost Contrast Enhanced Digital Mammogram (CEDM) protocol as a supplemental screening method to standard mammographic screening in women at intermediate lifetime-risk (and not undergoing annual MR surveillance) for breast cancer.

Researchers are trying to learn more about the prevalence of genetic mutations in women who are at intermediate/high risk of breast cancer and how that information my assist providers in improving screening and preventative options.

The purpose of this study is to improve the interpretation of mutations in breast cancer predisposition genes. This will be accomplished by recruiting members of families found to carry deleterious (mainly protein truncating) mutations and evaluating co-segregation of the mutations with cancer within families.
