Invasive breast carcinoma

This phase II trial tests whether combining the hormone therapy letrozole with standard chemotherapy before surgery can improve tumor shrinkage in people with ER-positive, HER2-negative breast cancer that grows quickly. Participants receive either six cycles of docetaxel, epirubi…

This trial is investigating whether cryoablation, a technique that freezes and destroys breast tumors with extreme cold, can be an effective alternative to surgery for certain patients. The study will include adults with localized breast cancer who cannot or choose not to have su…

This trial is testing whether treating only part of the breast with radiation is as effective as treating the whole breast in women with early-stage, low-risk breast cancer. Participants are women aged 40 and older who had breast-conserving surgery and did not have a sentinel lym…

This trial investigates whether adding neratinib, a drug that blocks HER2/3/4 proteins, to standard hormone therapy can improve disease control in people with metastatic ER+/HER2- breast cancer that has stopped responding to first-line endocrine therapy. Participants will receive…

This trial is investigating whether women with node-positive breast cancer whose lymph nodes are cancer-free after chemotherapy can safely receive less extensive radiation. Instead of radiating the entire lymph node region, the study compares standard radiation to a more targeted…

This phase 3 trial tests whether monitoring tumor DNA in the blood (ctDNA) can help doctors switch hormone therapy earlier in people with ER+/HER2- metastatic breast cancer. Participants whose ctDNA levels rise—before any symptoms or scans show progression—are randomly assigned t…

The SASHA trial is testing whether a single, high-dose radiation treatment delivered directly to the tumor site over one day is safe and effective for women with early-stage breast cancer. The study will enroll 134 women aged 40-85 who have already had a lumpectomy. Researchers w…

This study tests a new type of breast-conserving surgery that uses a small camera inserted through a hidden armpit incision to remove tumors, compared to the standard open approach. About 1,366 women with early-stage breast cancer will be randomly assigned to one of the two surge…

This study is testing whether people with certain non-invasive or early breast conditions (like ductal carcinoma in situ) can safely skip surgery and instead take hormone-blocking medication. The goal is to see if this approach keeps cancer from coming back over five years. The t…

This study tests whether combining two lymph node biopsy methods, sentinel lymph node biopsy and wire localized lymph node biopsy, can accurately identify breast cancer patients with only limited lymph node spread. The goal is to see if these patients can safely skip a more invas…

This study will develop and test an AI model that combines MRI, ultrasound, digital pathology, and patient data to predict how well breast cancer responds to neoadjuvant therapy. Researchers will analyze data from 1,800 participants across multiple centers. The goal is to help do…

This study tests whether a special ultrasound technique (super-resolution imaging) can predict if breast cancer will completely respond to chemotherapy after just one cycle. Researchers will enroll 150 women with invasive breast cancer scheduled for chemotherapy. The goal is to s…

This study tests a surgical technique done at the same time as breast cancer lymph node removal to prevent arm lymphedema (chronic swelling). The procedure uses a small flap of tissue from the side of the chest to rebuild the armpit area and support fluid drainage. One hundred hi…

Researchers are testing whether a 12-week supervised dance-based exercise program can reduce cancer-related fatigue in women with newly diagnosed breast cancer who are having treatment before surgery. The study includes 104 women aged 18 to 60 who will be randomly assigned to eit…

This study tests whether taking a high dose of whey protein after each workout helps breast cancer survivors gain more muscle and lose more fat compared to exercise alone. Participants are women aged 20 to 89 who have completed treatment for breast cancer and are prescribed exerc…

This study tests a new surgical approach for women with early breast cancer who need a nipple-sparing mastectomy. If cancer is found in the nipple during surgery, doctors will remove the nipple but try to save the pigmented skin around it (the areola) and rebuild a new nipple rig…

This study tests whether a simple home exercise program done for at least three weeks before breast cancer surgery can help women recover better. 54 women with early-stage breast cancer will be randomly assigned to either the exercise program or usual care. Researchers will measu…

This study tests a 6-month online program for women with newly diagnosed breast cancer. The program includes daily exercise, mindfulness, and support via email and optional group sessions. Researchers want to see if it reduces psychological distress and improves well-being compar…

This study compares removing drainage tubes earlier versus later after a specific type of nipple-sparing mastectomy with immediate breast implant reconstruction. About 379 women aged 18–70 with breast cancer or those having preventive mastectomy will take part. The goal is to see…

This study investigates whether different types of exercise can help middle-aged women reduce their body burden of PFAS (environmental chemicals) and improve muscle function. Participants will be assigned to either interval walking or high-intensity circuit training for six month…

This pilot study looks at how different resistance training routines change levels of myokines—molecules released by muscles during exercise—in women who have finished breast cancer treatment. Participants will be assigned to one of three exercise regimens (conditioning, strength…

This study tests whether taking omega-3 supplements before surgery can change the types of fats found in breast tumors. About 35 adults with early-stage breast cancer will take the supplement for 4 to 28 weeks while also receiving standard cancer treatments. The goal is to see if…

This study will follow 2,200 young women (aged 40 or younger) who had breast cancer and carry a mutation in a breast cancer gene other than BRCA1/2. Researchers want to see if getting pregnant after diagnosis affects the cancer's return. The study does not test any drug or treatm…

This study looks at whether tiny particles called exosomes, released by breast cancer cells, contain genetic material (microRNA) that can predict how well chemotherapy will work before surgery. Researchers will collect tumor tissue and blood samples from 60 women with breast canc…
