Comparing two treatments for low white blood cells during breast cancer therapy
This study compares two medications—Shengbai Oral Liquid and Leucogen Tablets—to help raise white blood cell counts in breast cancer patients whose counts drop during cancer treatment. Both drugs aim to help your body recover faster and allow you to continue your cancer therapy on schedule.
Shanghai, Shanghai MunicipalityAges 18–80 - NCT07587957Recruiting
Exercise and Brain Stimulation for Breast Cancer Survivors
This study tests whether combining exercise with a noninvasive brain-stimulation technique (tiny electrical pulses on the scalp) can help improve thinking and memory problems that some breast cancer survivors experience after treatment. Researchers want to see if this combination is practical and safe to use.
Boca Raton, FloridaAges 18 years+ - NCT07655934Recruiting
Lifestyle and energy in breast cancer survivors
This study looks at how lifestyle and energy levels affect women recently diagnosed with early-stage breast cancer. It may help researchers understand the body's changes during treatment.
Philadelphia, PennsylvaniaAges 18 years+ - NCT07549685Enrolling by invitation
Music Therapy to Help Breast Cancer Patients During Chemotherapy
This study tests whether music therapy can help women with breast cancer feel better during chemotherapy after surgery. Researchers will see if listening to or participating in music sessions improves quality of life and reduces stress during treatment.
