This randomized controlled clinical trial aims to evaluate the effect of electroacupuncture combined with self-acupressure on the quality of life of early-stage breast cancer patients receiving chemotherapy.

This study is a parallel-group, blinded (participant, evaluator, and statisticians), randomized controlled trial to investigate the effect of electroacupuncture combined with self-acupressure on the quality of life of early-stage breast cancer patients receiving chemotherapy.
