Pilot SMART of a Remotely Delivered, Physical Activity Intervention for Breast Cancer Survivors

The goal of this clinical trial is to evaluate the feasibility of randomizing participants to a "step-up" intervention pathway when they perform \<150 minutes of MVPA at the 6-week data collection burst. Participants who performed \<150 minutes of MVPA at the 6-week data collection burst will be randomized to either continue with the standard intervention or advance to the step-up intervention. The main questions it aims to answer are: 1. What percentage of participants who are eligible for the intervention phase enroll in the intervention phase? 2. Will participants assigned to the "step-up" intervention pathway demonstrate equal or greater rates of study retention and intervention engagement relative to those assigned to the standard intervention arm? 3. What percentage of the sample is performing \>150 minutes accelerometer measured MVPA/week at the intervention mid-point (week 6-data collection burst) and end-of-study (week 12-data collection burst)? 4. Do at least 50% of participants assigned to the "step-up" intervention pathway achieve a clinically meaningful volume of weekly MVPA by 12-weeks follow-up? All participants will: * Be assigned to either the Affect-based exercise prescription or the Effort-based exercise prescription. * Participate in three meetings with the interventionist (an exercise specialist) meant to help them get started increasing weekly exercise. These meetings are the same for all participants. * Be asked to wear an activity monitor and respond to brief surveys for 10 consecutive days at 4 points in time: Baseline, 2weeks, 6weeks, and 12weeks. Some participants (those performing \<150 minutes of MVPA at the 6-week data collection burst) will be assigned to the step-up intervention pathway. Participants assigned to the step-up intervention pathway will complete 3 additional follow-up meetings with the interventionist. During these meetings, the interventionist will help participants identify opportunities to be more active, set goals, and problem solve barriers to action.

Testing a Mammography Decision Intervention in a Rural Setting

The overall objective of this COBRE pilot project is to enhance the design of a 3-arm cluster randomized trial that will test the efficacy and mechanism of effect of the MyMammogram DA with or without a provider communication intervention. This will be accomplished through two aims: (1) Refine, with community partner input, a clinical trial protocol to optimize engagement among patients and primary care providers (PCPs) practicing in rural settings. In consultation with patients, PCPs, and informatics experts, the study team will refine site selection, randomization, patient and PCP recruitment, and data collection protocols to meet the needs of the rural health care delivery system and participants. The result of this aim will be a modified protocol and intervention strategy that is acceptable to partners. (2) Adapt and test trial and intervention implementation features to achieve protocol acceptance and adherence. The investigators will pilot the adapted three-arm randomized trial protocol in rural primary care settings that compares the MyMammogram DA with or without a risk summary provided to the PCP pre-visit, relative to usual care. Implementing the trial in two phases (n=15 each) will systematically identify barriers and facilitators to trial participation to refine protocols. Participants will receive acceptability surveys and investigators will conduct qualitative interviews with patients and PCPs to understand experiences with trial implementation from multiple perspectives.

Collection of CSF Samples From Participants With Metastatic Triple Negative Breast Cancer (TNBC) and HER2+ Breast Cancer With no Prior History Nor Active Radiographically Detectable Brain Metastases

Background: Breast cancer is the most common cancer among women. It can often spread to the liver, lungs, bones, or brain. Breast cancer that spreads to the brain is often fatal. Researchers want to know if tumor DNA found in spinal fluid, blood, or tumor tissue can help predict when the cancer will spread to the brain. They want to collect these fluid and tissue samples for research. Objective: To collect spinal fluid and other samples from people with breast cancer that has spread to other parts of the body. Eligibility: People aged 18 years and older with HER2-positive or triple negative breast cancer. The cancer must have spread to other parts of the body but not to the brain. Design: Participants will be screened. They will have blood tests to assess kidney function. They will have an imaging scan of the brain. Participants will come to the NIH clinic to have their samples collected: * Spinal fluid. A thin needle will be inserted into the lower back to draw out a sample of fluid from the space around the spinal cord. A physical exam and blood tests will be done to make sure it is safe for participants to have this procedure. * Blood. * Saliva or cheek swabs. They will rub a cotton swab inside of their mouth. * Tumor samples. If participants have had samples of tumor tissue (biopsies) collected in the past, leftover tissue may be used for this study. Participants will be contacted for follow-up every 6 months for 3 years. They may return once a year to provide further samples.

Promoting Informed Choice for Breast Cancer Screening: A Longitudinal Study

All participants will read a decision aid (DA) communicating evidence about mammography screening benefits and harms. Participants' evaluations of that evidence will be assessed, along with their screening intentions and receipt of screening. Participants will be sent 3 surveys via email and a final brief survey conducted by email or phone. The four surveys will be collected 1) upon enrollment and prior to the primary care appointment; 2) following the primary care appointment; 3) 3 months after enrollment; 4) 1 year after enrollment. The final 2 surveys will offer an increased incentive to increase retention rates.

Risk Communication Within Mexican-American Families

This study will examine what methods work best for encouraging Mexican-American family members to talk about their risk for diabetes, heart disease, breast cancer and colon cancer. Within the Mexican-American community, the family culture provides an important setting in which individuals interpret and share their health information and formulate strategies to engage in health-promoting behaviors. The information from the study will be used to design risk communication approaches for Mexican-American households. Members of households with at least three adults 18 to 70 years of age who are part of the existing Mexican-American households recruited by the University of Texas M.D. Anderson Cancer Center may be eligible for this study. Participants are interviewed about their medical history, family history of disease, health behaviors, beliefs about disease and disease risk, experiences living in the United States, and relationships with family members and close friends. They are then provided information about their family risk for diabetes, heart disease, breast cancer and colon cancer, based on the information they provided in the interview. Two additional interviews are conducted over the telephone that include questions about how the participants communicate with family members about their risk and health behaviors.

Natural History Study of Early Life Exposures in Agriculture (ELEA)

Study Description: ELEA is an observational cohort study that will collect exposure information and biospecimens from the adult children of the Agricultural Health Study (AHS) cohort (https://aghealth.nih.gov/about; Protocol OH93NCN013). The primary hypothesis is that early life exposures, particularly those found in the agricultural environment, are associated with cancer and other adverse health outcomes in childhood and early adulthood. Eligible individuals will be invited to complete an online questionnaire. After enrollment, study participants may be asked to donate biological and environmental samples. Participants will be followed for cancer and other disease endpoints. Data will be collected from North Carolina and Iowa health registries, disease specific databases, the National Death Index (NDI), North Carolina and Iowa state health registries, publicly available environmental datasets, discarded sample repository, and collection of available samples. Investigators will access data and biospecimens from the AHS protocol OH93NCN01 and link it to the ELEA population. In an earlier ELEA protocol (16CN095) the NCI SS IRB approved the protocol to perform linkages. That protocol was closed after the transition to the NIH IRB (per a NHSR determination), but the linkage work continued under the ELEA protocols that remained open with Westat and Iowa. Objectives: Primary: To investigate the effect of specific pesticides and other agricultural exposures and risk of cancer in children and adults. Secondary: To investigate the effect of non-agricultural exposures and the risk of cancer and other diseases in children and adults. Exploratory: Exploratory objectives include, but are not limited to, the examination of genetic and various molecular biomarkers in relation to childhood agricultural exposures. Endpoints: Primary: Incidence of Cancer Secondary: Incidence of diseases other than cancer, survival, and various molecular biomarkers. ...

Tissue Acquisition and Genomics Analysis of Breast Cancer and Other Gynecologic Malignancies

Background: A person s blood, tissue, and other samples contain DNA. Cancer is a disease of cells that are not working properly. It is caused by changes in DNA that build up. Researchers want to do future studies on DNA changes This may help them learn how to guide treatment for cancer. They need biological samples like tumors, blood, and urine for these studies. Objective: To create a place to collect and store biological samples from people with gynecologic malignancies like breast cancer. Samples from certain relatives of theirs will be collected too. Eligibility: Adults ages 18 and older who are being seen at NIH for breast cancer or other gynecologic malignancy Their biological relatives of the same age Design: Participants will answer questions about their family history. Participants will have a physical exam and medical history. This will include questions about age, ethnicity, and disease history. They will also answer questions about their medical treatments and responses. Participants will give blood and urine samples. Participants may give a tumor tissue sample. This will not be taken specifically for this study. It will be from a previous procedure or one that is already planned. Other samples may be taken only if a procedure is required for treatment. These include bone marrow, cerebrospinal fluid, and other fluids. A group of doctors and other professionals will oversee the sample storage place. The group will review all requests to be sure the use of the specimens is valid.

Precision Supplemental Imaging in Women With Dense Breasts

Recent research has shown that, among women with extremely dense breasts and normal results on mammogram, magnetic resonance imaging (MRI) use has significantly reduced the occurrence of breast cancer that is diagnosed during the time between two regular screening mammograms (also known as interval cancers). The investigators have developed and validated an approach to use the whole mammogram image, develop a mammogram risk score (MRS), and calibrate this to the SEER breast cancer incidence rates for US women. This model (Prognosia Breast) generates an absolute 5-year risk of breast cancer and classifies approximately 5.7% of the population as high risk using the ASCO 3% cut point as used for endocrine therapy to reduce risk. Follow-up generates an incidence of 25.2 cases per 1,000 women per year.
