This study is testing if electroacupuncture (using tiny electric pulses on acupuncture points) can help prevent nausea and vomiting caused by strong cancer drugs in breast cancer patients. Patients will get standard drugs like Olanzapine, NK-1RA (Neurokinin-1 receptor antagonists), 5HT3RA (serotonin receptor antagonists), and dexamethasone at the start of their chemotherapy. They will be randomly given real or fake (sham) acupuncture. The study checks if genes might predict who benefits from the treatment. Participants will note their nausea and vomiting and any extra medicine they take to stop it. Blood samples will be taken for further analysis.
- The study lasts for the duration of the chemotherapy treatment.
- Participants must be adults with breast cancer and meet specific health criteria.
- Not suitable for those who dislike electroacupuncture or have certain medical conditions.
