This early-phase trial tested a new drug called SRG-514 in 25 people undergoing breast-conserving surgery for breast cancer. The drug was given directly into the area where the tumor was removed. The main goal was to find a safe dose and check for side effects. This is a first st…

This study tested a new way to give radiation to people with early-stage breast cancer. Instead of many sessions, patients received just three doses aimed only at the tumor area. The goal was to see if this shorter treatment is safe and works well. 77 patients took part, and the …

This study tested whether a drug called ruxolitinib can reduce abnormal breast cells in people with high-risk or precancerous breast conditions like DCIS or atypical hyperplasia. Half of the 84 participants took ruxolitinib for about 15 days before surgery, and the other half too…

This study compared two radiation methods for people with early-stage breast cancer: a shorter, more focused radiation (accelerated partial breast irradiation) versus standard whole breast radiation. The goal was to see which causes fewer side effects like skin problems, breast s…

This phase II trial tested a 9-day course of whole breast radiation (hypofractionated radiotherapy) in 102 patients with early-stage breast cancer (stage 0-IIB). The goal was to see if a shorter treatment time could maintain effectiveness while reducing side effects. Researchers …

This study tested a new imaging dye called LS301-IT in 22 women with early-stage breast cancer (DCIS or stage I-II) who were having a partial mastectomy. The dye is injected into a vein before surgery to make cancer cells glow, helping surgeons see and remove them more accurately…

This study looked at whether MRI can more accurately measure the size of ductal carcinoma in situ (a very early form of breast cancer) compared to standard mammography. Forty women with the condition had MRI scans before surgery. Researchers then compared the MRI results with the…

This study tested whether a fast (abbreviated) breast MRI can detect cancers that mammograms miss in women who have already been treated for breast cancer with lumpectomy and radiation. Researchers recruited 184 women who had a normal 3D mammogram and gave them a quick MRI. The g…

This study tested a new handheld gamma camera (CarolIReS) in 110 breast cancer patients to see if it could find sentinel lymph nodes that standard methods miss. The camera was used before and during surgery to guide removal and check if any nodes were left behind. The goal was to…

This study tested whether a fluorescent dye called indocyanine green (ICG) can help surgeons locate small, non-palpable breast tumors during surgery. Ten women with early-stage breast cancer received both the dye and a standard radioactive seed, and doctors compared how well each…

Researchers are testing whether low-dose tamoxifen or a 5:2 intermittent fasting diet can raise levels of a protein called sex hormone binding globulin (SHBG) in women at high risk of breast cancer. Higher SHBG levels have been linked to lower breast cancer risk. The trial enroll…

This study follows up on women who took a low dose of tamoxifen (5 mg daily) for three years to see if it continues to prevent breast cancer over the long term. The original trial found a 42% reduction in breast cancer events. Researchers will also combine data from three similar…

This study tested two behavioral programs—coping skills training and general health education—to see which better improves well-being in people with ongoing pain after breast cancer surgery. About 316 participants who had surgery for breast cancer or precancerous conditions took …

This study compared two types of nipple-sparing mastectomy for breast cancer: one done with a robot and the other with traditional open surgery. 82 women took part, and the main goal was to see which approach led to higher patient satisfaction. The trial also looked at recovery t…

This study looked at whether using a special numbing technique (tumescent local anesthesia) during breast cancer surgery leads to less pain afterward compared to standard general anesthesia. 349 women who had breast cancer surgery took part. The goal was to see if this approach c…

This trial tested a new device called the Breast Cancer Locator (BCL), a custom plastic bra that helps surgeons find tumors during breast-conserving surgery. It was compared to the standard wire localization method in 480 women with non-palpable breast cancer. The goal was to see…

This pilot study tested an online program called THRIVE, based on Positive Affect Training, to help breast cancer survivors feel better about taking their anti-hormonal medication. The goal was to see if the program was acceptable and feasible for women who struggle with side eff…

This study looks at how doctors currently diagnose lung and breast cancer using tissue samples. It will also test whether artificial intelligence (AI) can help analyze these samples faster and more accurately. Researchers will review records from 600 patients to measure diagnosis…

This study gathers information from multiple hospitals about breast cancer in transgender and gender-diverse adults. Researchers want to understand how the cancer is found, what risk factors are involved, and how it is treated. The goal is to find ways to improve care and reduce …

This completed study analyzed tissue samples from 108 breast cancer patients to identify proteins linked to early cancer invasion. The goal was to find markers that could help assess the risk of tumor spread in patients without lymph node involvement. Researchers focused on listi…
