Hypofractionated radiotherapy with a tumor bed boost for early breast cancer
This study is testing a new type of radiation treatment for women with early breast cancer to see if it can better control the disease while shortening the time they need treatment.
-
Comparing 5-day and 9-day radiation for early-stage breast cancer
This study is testing whether a shorter 5-day radiation treatment is just as effective as a longer 9-day treatment for women with early-stage breast cancer after surgery.
-
Comparing surgical excision and radiotherapy followed by surgery for ductal carcinoma in situ
This study is testing whether having surgery right away or getting radiation therapy first followed by surgery is better for people with ductal carcinoma in situ (DCIS).
-
Registry for patients with ductal carcinoma in situ (DCIS)
This study is trying to see how the results of a specific test for ductal carcinoma in situ (DCIS) can change the treatment choices doctors make for patients with this condition.
-
A tool to help patients decide on contralateral prophylactic mastectomy for breast cancer
This study tests if an online tool can help women newly diagnosed with breast cancer make better choices about having a preventive mastectomy on the other breast.
