Protein supplement after breast cancer treatment
This study tests whether taking a protein supplement plus resistance training can help improve muscle and body composition after breast cancer treatment. It could be for you if you have finished active breast cancer treatment and have been doing strength training for at least 3 months.
Pittsburgh, PennsylvaniaAges 20–89 - NCT07699991Recruiting
Support program for breast cancer survivors
This study tests a navigation program to help breast cancer survivors get the support services they need after treatment. It is designed for people treated at the Stefanie Spielman Breast Center who may face extra barriers, such as being older, Black, Hispanic, or living in a rural area.
Columbus, OhioAges 18 years+ - NCT07703033Recruiting
Heart Impact Study for Breast Cancer Radiotherapy
This study looks at how information about the heart may affect treatment decisions for people receiving radiation therapy for breast cancer. It aims to help reduce heart-related side effects from treatment.
CopenhagenAges 35 years+ - NCT07698314Recruiting
Exercise study for women after breast cancer treatment
This study looks at how a supervised exercise program affects muscle-related substances (myokines) in women who have finished breast cancer treatment. It may help understand how exercise can support recovery.
Pittsburgh, PennsylvaniaAges 20–89 - NCT06648148Recruiting
Molecular markers for radiation response in breast cancer
This trial looks for biomarkers (biological signs) in breast tissue that might predict how well breast cancer responds to radiation therapy. It is for patients with ductal carcinoma in situ (DCIS) who are scheduled to receive radiation after surgery.
LjubljanaAges 18–75 - NCT07696637Recruiting
Mobile app for breast cancer surgery recovery
This study tests a mobile app to help people with breast cancer or a BRCA mutation who are having breast surgery with reconstruction. The app gives you information and support before and after surgery.
Vancouver, British ColumbiaAges 19 years+ - NCT04289935Recruiting
Vacuum biopsy before surgery to check treatment response
This trial studies a special vacuum-assisted biopsy taken just before breast surgery to see how well pre-surgery (neoadjuvant) chemotherapy worked. It may help doctors understand whether patients truly had a complete or near-complete response on scans, which can guide next steps.
SalzburgAges 18 years+ - NCT03788213Recruiting
Shorter vs longer radiation after breast cancer surgery
This trial compares giving breast radiation over one week versus three weeks after surgery. It aims to see whether the shorter schedule works just as well and is safe for people with certain types of early breast cancer.
Kolkata, West BengalAges 18 years+ - NCT06660628Recruiting
Radiation therapy with or without breath-hold for left breast cancer
This study compares two types of radiation therapy for left breast cancer: one using a breath-holding technique to protect the heart, and another without it. The goal is to see which is safer and more effective for women who have had surgery.
