Low Dose Tamoxifen With or Without Omega-3 Fatty Acids for Breast Cancer Risk Reduction
This phase II trial evaluates tamoxifen, with or without omega-3 fatty acids, for reducing risk of breast cancer among postmenopausal and overweight or obese women who are at increased risk of developing breast cancer. Tamoxifen is a selective estrogen receptor modulator. It works by blocking the effects of the hormone estrogen in the breast. Tamoxifen is approved by the Food and Drug Administration for prevention of breast cancer in women at increased risk. Omega-3 fatty acids have been shown to decrease the amount of fats made in the liver. Omega-3 fatty acids may work to prevent cancer in overweight or obese individuals. Tamoxifen with or without omega-3 fatty acids may be effective at reducing risk of breast cancer among women who are postmenopausal, overweight or obese, and at increased risk.

Acolbifene Versus Low Dose Tamoxifen for the Prevention of Breast Cancer in Premenopausal Women at High Risk for Development of Breast Cancer
This phase IIA trial compares the effect of acolbifene versus low dose tamoxifen in preventing breast cancer in premenopausal women at high risk for developing breast cancer. The usual approach for patients at increased risk for breast cancer is to undergo yearly breast magnetic resonance imaging or ultrasound in addition to yearly mammogram. Premenopausal women at very high lifetime risk for breast cancer (greater than 50%) can consider preventive removal (mastectomy) of both breasts. Premenopausal women age 35 or older with a prior diagnosis of atypical hyperplasia, lobular carcinoma in situ, or an estimated 10-year risk of greater than or equal to 3% or estimated 10-year risk of greater than or equal to 2-5 times that of the average woman (depending on age) may be advised to consider five years of standard dose tamoxifen. Standard dose tamoxifen is four times the dose used in this study. Estrogen can cause the development and growth of breast cancer cells. Acolbifene and tamoxifen blocks the use of estrogen by breast cells. This study may help researchers measure the effects of acolbifene and low dose tamoxifen on markers of breast cancer risk in mammogram imaging, breast tissue, and in blood samples.

Tamoxifen Citrate, Letrozole, Anastrozole, or Exemestane With or Without Chemotherapy in Treating Patients With Invasive RxPONDER Breast Cancer
This randomized phase III clinical trial studies how well tamoxifen citrate, anastrozole, letrozole, or exemestane with or without chemotherapy work in treating patients with breast cancer that has spread from where it began in the breast to surrounding normal tissue (invasive). Estrogen can cause the growth of breast cancer cells. Hormone therapy, using tamoxifen citrate, may fight breast cancer by blocking the use of estrogen by the tumor cells. Aromatase inhibitors, such as anastrozole, letrozole, and exemestane, may fight breast cancer by lowering the amount of estrogen the body makes. Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether giving tamoxifen citrate, anastrozole, letrozole, or exemestane is more effective with combination chemotherapy in treating patients with breast cancer.

Comparing Supplemental Topical Agents for the Treatment of Acute Radiation Dermatitis in Patients With Breast Cancer
This clinical trial compares two supplemental topical agents (Aquaphor and Miaderm) for the treatment of acute radiation dermatitis in patients with breast cancer undergoing radiation therapy. Radiation dermatitis is a radiation-induced skin reaction which can cause itching, swelling, pain, and general discomfort. Aquaphor is a commonly available, inexpensive, petrolatum-based multi-purpose ointment designed to protect and sooth extremely dry skin, chapped lips, cracked hands and feet, minor cuts and burns, and many other skin irritations. Miaderm is a water-based cream and contains ingredients like calendula, hyaluronate, and aloe vera which may help reduce occurrence and severity of radiation dermatitis. Both are commonly recommended and used by breast cancer patients undergoing external beam radiation therapy (EBRT). However, it is not known whether one is better than the other in treating or preventing radiation dermatitis.

High Cannabidiol Plant Extract (BRC-001) to Improve Aromatase Inhibitor-Induced Arthralgia in Women With Breast Cancer
This phase II trial tests the effectiveness of cannabidiol (CBD) plant extract (BRC-001) in improving joint stiffness and pain (arthralgia) in women with breast cancer taking aromatase inhibitors (AIs). AIs lower blood levels of estrogen in postmenopausal women to reduce breast cancer recurrence. Women on AI therapy may experience joint stiffness, pain and arthritis symptoms as a side effect of the medication. Some women stop AI therapy due to these side effects and do not receive the maximum benefit from the medication. CBD is derived from the same plant family as marijuana but is not associated with a "high" or mind-altering effect and is not habit-forming. Research in animals and humans indicates that CBD might decrease inflammation in joint tissues and may help reduce chronic pain in ailments such as arthritis. BRC-001 may reduce joint pain in women with breast cancer taking AIs.

Volumetric Specimen Imager Device for the Intraoperative Imaging of Patients With Breast Carcinoma and Breast Ductal Carcinoma In Situ, The VIVID Study
This clinical trial assesses if the use of a three-dimensional imaging device called the Clarix Imaging Volumetric Specimen Imager (VSI) can help guide and assist surgeons in identifying and removing all positive margins while in the operating room (intraoperative imaging) for patients with breast cancer and breast ductal carcinoma in situ. Breast conservation surgery or lumpectomy is a standard of care (routine) procedure that removes the tumor and a rim of surrounding normal tissue (margins) while leaving as much normal breast tissue as possible. A margin that does not contain tumor cells is called a negative margin and tells the surgeon that the primary tumor has been removed. A positive margin contains tumor cells at or near the edge of the tissue removed. As part of standard of care, surgeons take two-dimensional x-ray images of the tissue that has been removed in the operating room to assess if there is any additional tissue that should be shaved (removed) to get a negative margin. After the surgery is over, the tissue is examined once again by a pathologist in a laboratory to determine if there are any small pieces of tumor left in the margin that were not visible during surgery. If residual tumor is detected in the margin, a reoperation may be required to remove additional tissue until the tumor has been completely removed from the margin. Diagnostic procedures, such as intraoperative volumetric specimen imaging may reduce the rate of reoperation of for patients who previously underwent lumpectomy.
