RATIONALE: Chemoprevention is the use of certain drugs to keep cancer from forming, growing, or coming back. The use of simvastatin and anastrozole may stop cancer from forming, growing, or coming back in patients with invasive breast cancer, ductal carcinoma in situ, or a high risk of breast cancer. PURPOSE: This phase II trial is studying how well giving simvastatin together with anastrozole works in treating postmenopausal women with invasive breast cancer, ductal carcinoma in situ, or a high risk of breast cancer.
RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Giving radiation during surgery followed by external-beam radiation to the entire breast may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of radiation therapy during surgery followed by whole-breast radiation therapy in treating women who have undergone lumpectomy for ductal carcinoma in situ or invasive breast cancer
This clinical trial studies magnetic resonance imaging (MRI) and gene expression in diagnosing patients with abnormal cells in the breast duct that have not spread outside the duct. MRI uses radio waves and a powerful magnet linked to a computer to create detailed pictures of areas inside the body. MRI may help find and diagnose patients with breast cancer. It may also help doctors predict a patient's response to treatment and help plan the best treatment. Genetic studies may help doctors predict the outcome of treatment and the risk for disease recurrence. Performing MRI with genetic studies may help determine the best treatment for patients with breast cancer in situ.
This randomized phase II trial studies how well hypofractionated radiation therapy (RT) works compared to standard RT in treating patients with ductal breast carcinoma in situ (DCIS) or early invasive breast cancer. Radiation therapy (RT) uses high energy x-rays to kill tumor cells. Giving higher doses of RT over a shorter period of time may kill more tumor cells and have fewer side effects. It is not yet known if hypofractionated RT is more effective than standard RT in treating breast cancer.
RATIONALE: Collecting samples of blood and tissue from patients with cancer to study in the laboratory may help doctors learn how fluvastatin effects biomarkers related to breast cancer. PURPOSE: This randomized phase II trial is studying how fluvastatin effects biomarkers in women undergoing surgery for ductal carcinoma in situ or stage I breast cancer.
There is no granular retrospective data on breast cancer in transgender and gender-diverse (TGD) persons from a contemporary and diverse American cohort. The purpose of this investigation is to aggregate data from multiple institutions to describe the risk, diagnosis, management, and outcomes of TGD persons with breast cancer in effort to identify opportunities for future intervention studies to eliminate breast cancer disparities for this population.
The purpose of this pilot study is to determine the prevalence of markers of chronic and cycling hypoxia and reactive species stress (oxidative and nitrosative) in the breast cancer tumor microenvironment. The study is based around four cornerstone features of the pathologic microenvironment - Hypoxia, Reactive Species (reactive oxygen and nitrogen species), HIF-1 and VEGF, which we term the HRHV axis. Fifty breast cancer patients with planned surgical excision will be administered the hypoxia marker drug, EF5, 24-36 hr prior to surgical excision. EF5 is a non-therapeutic drug and provides no direct benefit to those patients enrolled in this pilot study. Tissues obtained intra-operatively will be snap frozen and subsequently analyzed for EF5 binding. Immunohistochemical analysis of a cohort of immunohistochemical and urine markers that depict the HRHV axis will be examined. The association of the markers with the presence of hypoxia, as determined by EF5 positivity, will be determined. Data from this pilot study will be used to establish the prevalence of markers of the HRHV axis in breast cancer. This information will be crucial for future human trials in which the HRHV axis is therapeutically targeted.

PURPOSE: This clinical trial is studying blood samples from women with breast cancer or ductal carcinoma in situ who are receiving tamoxifen.
RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Placing gold markers in the area where the tumor was removed may help doctors better direct radiation therapy and help reduce the risk of cancer recurrence. PURPOSE: This phase I trial is studying how well radiation therapy using gold markers works in treating women with early-stage breast cancer.
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.
RATIONALE: Gathering information about how patients respond to stress and measuring stress levels in women with newly diagnosed breast cancer may help doctors provide better methods of treatment and on-going care. PURPOSE: This research study is measuring stress in women with newly diagnosed stage I, stage II, or stage III breast cancer or ductal carcinoma in situ of the breast.
