Acupuncture is a traditional Chinese method of medical treatment and a popular modality for treating musculoskeletal pain. Acupuncture involves the use of thin needles to stimulate specific points of the body and leads to pain control through the release of endorphin in the central nervous system. Clinical trials have found a benefit of acupuncture for the treatment of knee and back pain. Given the lack of effective treatments for AI-induced joint pain and the safety and efficacy of acupuncture, it is therefore reasonable to evaluate whether acupuncture is effective in breast cancer patients who experience musculoskeletal pain related to AIs.
