Breast carcinoma in situ

This study tests a shorter, more focused radiation treatment (hypofractionated partial breast irradiation) for women with early-stage breast cancer. The goal is to see if targeting only the tumor site can reduce side effects and improve cosmetic outcomes compared to standard whol…

This early-phase trial is testing a gel form of the drug endoxifen, applied to the skin, in 32 women scheduled for breast surgery. The goal is to see if the gel is safe and how much of the drug gets into breast tissue and blood. If successful, it might offer a gentler way to trea…

This phase III trial compares low-dose tamoxifen to standard hormone therapy (aromatase inhibitors) in postmenopausal women with low-risk, hormone-positive, HER2-negative early breast cancer. The goal is to see if the lower dose works just as well to prevent cancer from coming ba…

This phase III trial tests whether adding pembrolizumab (Keytruda) after standard chemotherapy can help prevent triple-negative breast cancer from coming back. Over 1,100 patients with residual cancer after chemo are randomly assigned to receive pembrolizumab or placebo. The stud…

This phase 2 trial tests whether giving radiation once a day for five days (instead of every other day) can keep the breast looking good after treatment. It includes 48 women aged 40 or older with low-risk, hormone-sensitive breast cancer. The goal is to see if this shorter sched…

This study tests a shorter course of radiation (hypofractionated) to the breast and nearby lymph nodes in 137 women with node-positive breast cancer. The goal is to see if this approach reduces arm swelling (lymphedema) and other side effects while still preventing cancer from co…

This study tests whether a single, focused radiation treatment works as well as five treatments for people with low-risk stage 0 or I breast cancer after a lumpectomy. About 134 participants will be randomly assigned to receive either one or five doses of radiation to the tumor a…

This phase II trial is testing a type of radiation called proton beam therapy for women with early-stage breast cancer (stage 0 to II). The goal is to see if this targeted approach can kill cancer cells while causing less damage to normal tissue, leading to fewer side effects and…

This study compares a 1-week radiation schedule to the standard 3.1-week schedule for people with early-stage breast cancer who have had lumpectomy. The goal is to see if the shorter course controls cancer just as well while causing fewer side effects. About 72 adults with ductal…

This study tests whether giving an extra dose of radiation (a boost) before breast cancer surgery is safe and helpful. About 103 people with early-stage breast cancer that hasn't spread will receive the boost, then standard radiation and surgery. The goal is to see if this approa…

This study tests whether giving two drugs (trastuzumab and a taxane) before surgery can shrink HER2-positive breast carcinoma in situ tumors enough to allow breast-conserving surgery instead of mastectomy. About 54 women aged 18-70 with tumors at least 2 cm will receive 4-6 cycle…

This large study is testing whether a new laser-based blood test can help screen for breast cancer. Researchers will compare blood samples from women with and without breast cancer to see if the test can accurately spot the disease. If it works, it could offer a less invasive way…

This phase 3 trial tests whether taking metformin for 12 months can reduce abnormal cells in the breast tissue of women at high risk for breast cancer. Participants have conditions like atypical hyperplasia or a strong family history. Researchers compare metformin to a placebo to…

This study tests whether adding a photo guide to standard counseling helps reduce anxiety and depression in women with early-stage breast cancer who are about to start radiation therapy. About 62 participants will either receive standard verbal counseling alone or with a pictoria…

This study looks at whether hypnosis can help women with early-stage breast cancer relax during surgery, possibly reducing the need for general anesthesia. About 50 women will try hypnosedation, a technique that uses words and images to keep them calm and awake while numb. The go…

This study looks at whether a culturally tailored writing program can improve the well-being of Chinese immigrant women who had breast cancer (stages 0 to III). About 256 women who finished their main cancer treatment in the last 5 years will write about their experiences. The go…

This study tests whether a high-CBD plant extract can reduce joint stiffness and pain in women with breast cancer who take aromatase inhibitors. These drugs lower estrogen to prevent cancer return but often cause painful joints, leading some women to stop treatment. The trial wil…

This study tests a web-based portal called YES (Young, Empowered & Strong) designed to help adolescent and young adult breast cancer survivors monitor and manage their symptoms. Researchers will compare the quality of life of 400 women who use the portal to those receiving standa…

This study looks at whether advanced breast MRI can tell the difference between harmless and dangerous breast calcifications, which are often a sign of very early-stage breast cancer called DCIS. About 122 women with suspicious calcifications or recent DCIS diagnosis will get an …

This study is a registry that tracks side effects and outcomes in people who have undergone cryoablation (freezing) for early stage breast cancer. It is not testing a new treatment but rather collecting real-world data on symptoms, complications, and follow-up results. Only 2 par…

This study looks at whether web-based decision support tools can help women with atypical hyperplasia or lobular carcinoma in situ (conditions that raise breast cancer risk) make informed choices about chemoprevention. About 412 women and their healthcare providers will use educa…

This study aimed to compare a less invasive procedure called vacuum-assisted excision (VAPE) to standard surgery for removing non-cancerous but high-risk breast lesions. The goal was to see if VAPE worked as well, was safer, and left better cosmetic results. However, the study wa…

This study tests a decision aid designed to help people with early-stage breast cancer become more involved in choosing their surgery. It focuses on patients who face financial or social challenges, to see if the tool helps them feel more confident and speak up during doctor visi…

This study collects blood, tissue, and saliva samples from 7,000 people—both those with breast cancer and healthy volunteers. Researchers at Memorial Sloan Kettering will use these samples to study what causes breast cancer and find better ways to prevent, detect, and treat it. N…

This study looks at 800 people with a type of breast cancer called lobular breast cancer. Researchers are searching for inherited gene changes that may raise cancer risk. Depending on the gene found, patients may get closer monitoring or preventive surgery. The goal is to tailor …
