Clinical Trials

The purpose of this study is to understand the causes of breast cancer, in particular the connection between genetic variations and breast density or how tissue is distributed on a mammogram.

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 purpose of this study is to confirm that the Stereo Navigator accessory to an MBI Imging system can successfully guide the sampling of abnormal MBI findings in patients with known or suspected breast cancer.

We aim to determine if Molecular Breast Imaging (a new nuclear medicine technique developed at Mayo) can identify malignant breast lesions in women who have atypical ductal hyperplasia, atypical lobular hyperplasia, or lobular carcinoma in situ.

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 primary objective of this study is to determine if exercise, fasting, or eating prior to the molecular breast imaging study will have an effect on the uptake of the tracer in the breast tissue.

The purpose of this study is to apply new microvasculature imaging for differentiation of breast lesions, and prediction of response to preoperative chemotherapy.

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.

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.

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 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.

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.
