BRCA Mutations in Latinas
Background: \- BRCA1 and BRCA2 gene mutations have been linked to a higher risk of developing breast cancer and other cancers, and may be associated with types of breast cancer that are more difficult to treat and more likely to recur. New cancer treatments are being developed specifically to treat individuals who have these gene mutations. However, more information is needed about the prevalence of these mutations in minority populations, including Hispanic/Latino populations. To study these populations, researchers are interested in collecting genetic material (DNA) and medical history information from Hispanic/Latino women who have been diagnosed with breast cancer. Objectives: \- To collect saliva samples and medical and family history information from Hispanic/Latino women with breast cancer. Eligibility: \- Hispanic/Latino women at least 18 years of age who have been diagnosed with breast cancer. Design: * Participants will complete a questionnaire with information about place of birth, languages spoken by parents and grandparents, and information about their breast cancer diagnosis. * Participants will provide a saliva sample (2 to 3 tablespoons) for analysis. * No treatment will be provided as part of this protocol.

A Clinical Study of Sacituzumab Tirumotecan (Sac-TMT, MK-2870) in People With Breast Cancer (MK-2870-032)
Researchers are looking for new ways to treat types of breast cancer that are both: * High-risk, which means the cancer may have a higher chance of getting worse or coming back after treatment * Early-stage, which means the cancer is in the breast or the lymph nodes around the breast The 2 types of breast cancer in this study are triple-negative breast cancer (TNBC) and hormone receptor (HR)-low positive/human epidermal growth factor receptor-2 (HER2) negative breast cancer. These cancers have zero or a low amount of a protein called HER2 and other proteins that attach to the hormones estrogen or progesterone. Sacituzumab tirumotecan (also known as sac-TMT or MK-2870), the study medicine, is a type of targeted therapy. A targeted therapy is a treatment that works to control how specific types of cancer cells grow and spread. The main goals of this study are to learn if people who receive sac-TMT, pembrolizumab, and chemotherapy: * Have fewer cancer cells found in the tumors and lymph nodes removed during surgery compared to those who receive only pembrolizumab and chemotherapy * Live longer without the cancer growing, spreading, or coming back compared to people who receive only pembrolizumab with chemotherapy

A Clinical Study of Patritumab Deruxtecan to Treat Breast Cancer (MK-1022-016)
Researchers are looking for other ways to treat breast cancer (BC) that is hormone receptor-positive and human epidermal growth factor receptor 2-negative (HR+/HER2-) and either unresectable locally advanced or metastatic. * HR positive (HR+) means the cancer cells have proteins that attach to estrogen or progesterone (hormones) which help the cancer to grow and spread * HER2 negative (HER2-) means the cancer cells have a low amount of a protein called HER2 * Unresectable locally advanced means the cancer cannot be completely removed by surgery and has spread into nearby tissue or muscles * Metastatic means the cancer has spread to other parts of the body Treatment for this type of breast cancer usually includes endocrine therapy (ET) and sometimes a second treatment. The main goal of this study is to learn if people who receive patritumab deruxtecan (also known as HER3-DXd and MK-1022) live longer overall or without the cancer growing/spreading, compared to people who receive chemotherapy or a different drug called trastuzumab deruxtecan.

A Study of Imlunestrant (LY3484356) in Premenopausal Women With Estrogen Receptor-Positive (ER+) Human Epidermal Growth Factor Receptor 2 Negative (HER2-) Early Breast Cancer
This study will include two groups of patients: Cohort 1 and Cohort 2. Cohort 1: will help researchers learn how a medicine called imlunestrant (LY3484356) affects a specific type of breast cancer. Some patients will take both imlunestrant and another treatment to suppress their ovarian function. Some will take it without ovarian suppression. Researchers will compare the effects in breast cancer cells to those of another medicine called tamoxifen. All patients in this group will be premenopausal women who have a type of early breast cancer called estrogen receptor-positive, HER2-negative. The treatment in this group will last for up to 29 days. Cohort 2: will help researchers understand how imlunestrant affects the ovaries when it is taken without ovarian suppression. Researchers will compare the effects to those of another medicine called tamoxifen. This group will also include premenopausal women with the same type of breast cancer. The treatment in this group will last for up to 6 months.

Non-Contrast Breast MRI Diagnosis and Risk Stratification Using DWI-Generated Synthetic Contrast Enhancement
The goal of this observational study is to develop an integrated breast MRI system that uses diffusion-weighted imaging (DWI) to create synthetic contrast-enhanced images. This system aims to diagnose and screen for breast cancer without the need for contrast agents, while using a generated risk score to perform imaging-based triage and risk stratification. Participants will include people aged 18 and older who require a breast MRI either for evaluation of a suspicious finding or for high-risk screening. This study seeks to answer two main questions: * Can synthetic contrast-enhanced images generated from DWI match real contrast-enhanced images in their ability to distinguish benign from malignant breast lesions? * Can the risk score derived from DWI-based synthetic images enable imaging-level risk stratification, allowing people at lower risk to avoid contrast agent injection? Researchers will compare the quality of synthetic images against real contrast-enhanced images and will recruit radiologists to assess how well these images perform for diagnostic and screening tasks. MRI data from participants undergoing breast MRI will be used to train, validate, and test this integrated system.

Breast Cancer, Reasoning, and Activity Intervention
This phase II trial tests whether an exercise intervention works to improve cognitive function in breast cancer survivors. Many breast cancer survivors report cancer-related cognitive impairment, which this has recently become a priority in clinical research due to its dramatic impact on daily functioning, quality of life, and long-term health. Aerobic exercise has the potential to improve cognitive function and brain health in older adults and is recommended as a safe, tolerable, and accessible complementary therapy for breast cancer survivors. This study aims to understand the effects of physical activity compared with health education on memory, attention, and brain health in women with breast cancer. Study findings may help researchers design more programs that can improve memory, attention, and brain health in other women with breast cancer.

AI-Based Phenome Data Analysis for Predicting the Onset of Major Diseases
This study aims to develop and validate an artificial intelligence (AI)-based predictive model to estimate the risk of incident onset of five major diseases or conditions: cardiovascular disease, type 2 diabetes mellitus, breast cancer, low back pain, and osteoarthritis, in adults aged 30 to 60 years. For each participant, an index date will be defined as the date of a prior health screening or another protocol-defined baseline clinical date. Incident disease status for each target disease or condition will be ascertained by retrospective review of electronic medical records for up to 10 years after the index date. The study integrates retrospective clinical, health screening, laboratory, imaging, and electronic medical record data with prospectively collected biospecimen, proteomic, genomic, questionnaire, lifestyle, and digital health data. Prospective study procedures will be completed over approximately 1 week, with up to 2 additional weeks if needed. By combining multimodal data, this study seeks to improve disease risk prediction and to identify clinical and biological factors associated with disease onset, ultimately supporting personalized risk stratification and preventive healthcare strategies.

PI-targeted PNE+MI Compared to BIOMEDICAL Education in BCS
Breast cancer is the most frequently diagnosed cancer in women worldwide. An important portion of the breast cancer survivors will face chronic pain complaints. These pain complaints do not only impact the patient's quality of life but also prevents resumption of activities, leading to huge economic costs. 30% of all breast cancer survivors with pain present with perceived injustice which has been conceptualized as a multidimensional appraisal process characterized by a tendency to interpret one's losses as severe and irreparable, to attribute blame to others for one's suffering and to experience a sense of unfairness. Perceived injustice is also associated with increased opioid prescription and use, urging the need for targeted interventions to diminish perceived injustice. Despite the fact that specific treatment plans for perceived injustice are not yet proven, pain neuroscience education (PNE) is proven to reassure and encourage towards activity. In order to obtain the targeted behavioural change, motivational interviewing (MI) is used as the communication process throughout PNE. A multi-centre, parallel, two-arm, investigator-blinded study with 4-weeks intervention and two years follow-up will be conducted in 156 BCS with PI and pain. These will be randomly assigned to the intervention or usual care group. The groups will receive 1 online session, an information leaflet and 3 live sessions of education spread over 4 weeks. Pain neuroscience education in combination with motivational interviewing will be given in the experimental group and biomedically-focused education to the control group. The primary scientific objective of the study is to examine whether perceived injustice-targeted PNE is superior to biomedically-focused pain education in reducing pain after 12 months in breast cancer survivors with perceived injustice and pain. The secondary objectives of the study are to examine whether perceived injustice-targeted PNE, compared to biomedically-focused pain education, results in improving health-related quality of life, reducing perceived injustice and opioid use after 24 months in breast cancer survivors with perceived injustice and pain, and to conduct a health-care cost analysis which will finally result in a recommendation concerning the use of perceived injustice-targeted PNE in breast cancer survivors with perceived injustice and pain.
