Prevention of Breast Cancer: As Simple as hCG-A Randomized Clinical Trial in High Risk Women

The purpose of the study is to evaluate whether hCG will result in a decrease in breast density. High breast density has been associated with an increased risk in breast cancer. It has also been shown that decreasing density with a drug called tamoxifen has resulted in a decreased risk in breast cancer. The investigators are looking at the effect of hCG on breast density in people who are at increased risk of developing breast cancer and our theory postulates that throug...

A Study to See Whether Adding Night-time Compression to the Standard Care Will Result in Improved Control of Arm Swelling (Lymphedema) in Breast Cancer Subjects

Lymphedema (significant arm swelling on the surgical side) is one of the most common complications following treatment for breast cancer. The impact of lymphedema is profound, resulting in negative self image, increased anxiety and poorer quality of life. In time, lymphedema can result in recurrent infections in the arm, functional impairment and pain. Approximately 21% of women who undergo breast cancer treatment develop lymphedema. Unfortunately this is a life-time conditi...

Changes in Breast Density and Breast Cancer Risk in Women With Breast Cancer and in Healthy Women

RATIONALE: Studying mammograms for breast density changes over time may help doctors predict breast cancer risk. PURPOSE: This natural history study is looking at changes in breast density and gathering health information over time to assess breast cancer risk in women with breast cancer and in healthy women.

Genetic Risk Estimation of Breast Cancer Prior to Preventive Medication Uptake

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

Partial Breast Versus no Irradiation for Women With Early Breast Cancer

All early breast cancer patients are offered adjuvant breast radiation therapy (RT) after breast conserving surgery for an early breast cancer. Breast cancer is heterogeneous, and selected patients have a very low gain from RT, whilst they still have risk of acute and late side effects from RT. This trial will try identify selection criteria for low risk breast cancer patients who can safely omit adjuvant RT without unacceptable high risk of local failure.

High Risk Breast Cancer Screening Program

Objectives: - To screen population with high risk for breast cancer - To promote the concept and importance of surveillance mammography - To find out the incidence of breast cancer in population who are in high risk for breast cancer - To collect blood samples for molecular analysis

Breast Study to Learn More About the Application of Optical Transillumination Measurements to Assess Breast Cancer Risk and to Potentially Detect the Presence of Breast Cancer.

This study aims to evaluate if a light based technique, called Transillumination Breast Spectroscopy (TIBS), can be used to construct a non-invasive breast cancer risk predictor which provides a better odds ratio than mammographic parenchymal density.

Clinical Implementation of a Polygenic Risk Score (PRS) for Breast Cancer

This study aims to assess how a polygenic risk score (PRS) reported with the results of multi-gene panel testing affects the breast cancer risk management recommendations healthcare providers make to their patients. The PRS is a score based on small genetic changes, clinical history, and family history. The PRS is used to estimate remaining lifetime risk of developing breast cancer for patients with no personal history of breast cancer and an overall negative result from MGPT.

Menopausal Symptoms in Women With Breast Cancer or At High Risk of Breast Cancer Treated on Another Clinical Trial

RATIONALE: Gathering information about the frequency and intensity of hot flashes in patients with breast cancer and in patients who have a high risk of developing breast cancer may help doctors learn more about menopausal symptoms. PURPOSE: This clinical trial is looking at menopausal symptoms in women with breast cancer or at high risk of breast cancer who received treatment on another clinical trial.

ENGAGED 2 Study: Experiences With Mammography Screening and Breast Density 2

This trial will test a decision support web based intervention for women at increased risk for breast cancer due to breast density and other risk factors (age, race/ethnicity, family history of breast cancer, history of prior breast biopsies), and to consider MRI and/or chemoprevention to manage their breast cancer risk.

Immediate Breast Reconstruction With Free Greater Omentum

Luminal subtype breast cancer, accounting for 70 to 80% of all breast cancers, has been reported to be associated with good prognosis. However, for the patients with large mass or worse mass position, free greater omentum transplantation may provide a new option for breast reconstruction.

Facilitating Web-based Patient Decision Support: Decision About Medication to Lower Breast Cancer Risk

Background: - Chemoprevention is the use of preventive medications to reduce the risk of breast cancer for women who are at a high risk of developing the disease. Although the treatment has shown effectiveness in preventing cancer development, chemoprevention is notably underutilized even by women who are at a high risk of developing breast cancer. - Researchers are interested in determining if better decision support mechanisms, such as intera...

Breast Cancer Recurrence Risk Counseling

The number of breast cancer survivors is growing. Women with a personal history of breast cancer worry about their risk of getting cancer again. The current study will develop counseling about breast cancer recurrence risk and will also get an estimate of the preliminary impact of this counseling. The goal is to enable women to make better decisions about their treatment.

Cell Lines From High-Risk Breast Tissue

Background: - Many risk factors for breast cancer have been identified, including family history, endocrine background, changes in breast tissue, cancer in one breast, radiation exposure, obesity and others. There is a spectrum of tissue changes seen in cancerous and pre-cancerous breast tissue. - A cell line is a collection of cells that are grown in the laboratory from an original tissue specimen. Cell lines developed from high-risk breast ti...

Molecular Mechanisms of Clinical Resistance to Targeted Therapy Among Patients With Breast Cancer

The purpose of this study is to learn why certain drugs stop working in patients.In lab studies, tumors become resistant in several ways. Specific molecules seem to change and this may be why therapy stops working. However, we do not know if the same molecules change in patients. This study is being done to see if they do change. If we learn more about how patients become resistant, we may be able to offer better treatment in the future.

Study of Individuals and Families at High Risk for Breast or Ovarian Cancer

RATIONALE: Studying individuals and families at high risk for breast or ovarian cancer may help in identifying the genes involved in the development of breast and ovarian cancer and help to identify other persons at risk for cancer. PURPOSE: Study to identify genetic, behavioral, and environmental factors related to cancer risk in individuals and families at high risk for breast or ovarian cancer.

Temsirolimus Plus Neratinib for Patients With Metastatic HER2-Amplified or Triple Negative Breast Cancer

The purpose of this study is to test the safety and benefit of two new drugs for the treatment of breast cancer. The patient is eligible for the study because their breast cancer has grown in spite of standard treatment. The two drugs tested in the study, Neratinib and Temsirolimus, will be given together. Also, this study will help the investigators learn why therapy directed against HER2 sometimes stops working.

Automated Quantification of Coronary Artery Calcifications on Radiotherapy Planning CTs for Cardiovascular Risk Prediction in Breast Cancer Patients: the BRAGATSTON Study

The aim of the BRAGATSTON study is to provide a low cost tool for measuring CAC in breast cancer patients, thereby identifying patients at increased risk of CVD. Breast cancer patients and doctors can act upon this, by adapting the treatment and/or by adopting cardioprotective interventions. Hereby, the burden of CVD in breast cancer survivors can be reduced and better overall survival rates can be achieved.

Melatonin Versus Placebo in Breast Cancer

The purpose of this research study is to determine whether melatonin taken every night can affect blood levels of estrogen or IGF (insulin-growth factor levels). Both IGF and estrogen are normally produced in the body and may influence breast cancer risk. Melatonin is also naturally produced in the body. Laboratory studies have shown that melatonin may decrease cancer growth and influence estrogen and IGF levels. Melatonin's effects on sleep, hot flashes, and mood will also be ...

Phase IIb Trial of G-2535 (Unconjugated Isoflavones-100) in Women at High Risk for Breast Cancer

RATIONALE: Chemoprevention is the use of certain drugs to keep cancer from forming, growing, or coming back. The use of genistein may prevent breast cancer in women at high risk for breast cancer. PURPOSE: This randomized phase II trial is studying how well genistein works in preventing breast cancer in women at high risk for breast cancer.

Impact of Body Mass Index on Outcomes of Breast Cancer Management

Obesity has been linked to an increased risk of developing a number of malignancies, including postmenopausal breast cancer. One of the established risk factors for breast cancer development in post-menopausal women is obesity which has further been linked to breast cancer recurrence and poorer survival in pre- and post-menopausal breast cancer.

Quadrant High Dose Rate Intraoperative Radiation Therapy (IORT) for Early-Stage Breast Cancer: A Pilot Study

This study was started to validate the possibility of administering radiation therapy during surgery to the tissue surrounding the tumor once the tumor has been removed. This surrounding breast tissue is at greater risk for developing breast recurrences. This treatment may be as effective as the conventional 5-6week radiation treatment in reducing the risk of further local recurrences after breast-conserving surgery. Through this study, we would like to confirm that this proce...

Markers for Predicting Risk of Breast Cancer in Women of Different Races

This research is being done to learn more about the risk of developing breast cancer by studying cells from both normal breast tissue and breast cancer tumor tissue. The goal is to study cells, genes, and gene products to help us to learn how to detect cancer in its earliest stages, and if this information may differ in patients with different ethnic backgrounds.

Sleep, Circadian Hormonal Dysregulation, and Breast Cancer Survival

Recent research provides evidence that disrupted circadian rhythms, including hormonal patterns and sleep, are associated with increased risk of breast cancer incidence and faster progression to mortality. We have observed that a loss of normal diurnal cortisol rhythm associated with more awakenings during the night predicts early mortality with metastatic breast cancer. Other recent studies have shown that nighttime shift work is associated with higher breast cancer incidence,...

A Survey of Sleep Problems in Survivors of Breast Cancer

The purpose of this study is to gain greater understanding of the problems breast cancer survivors experience related to difficulty sleeping and insomnia. Poor sleep can affect a person's mood, increase feelings of fatigue, as well as pain. A greater knowledge and understanding of sleep disturbances can lead to more effective treatment of sleep problems and significantly improve quality of life.
