Traditional acupuncture (TA) can reduce the frequency of hot flushes and night sweats (HF&NS), and improve physical and emotional well-being in women taking tamoxifen for breast cancer.  In a single-arm observational study 50 participants with early breast cancer received eight weekly, individualised TA treatments using a core standardised acupuncture protocol developed to treat HF&NS in natural menopause. Mean frequency of HF&NS was reduced by 49.8% at end of treatment (EOT) compared with baseline. Perceptions of HF&NS as a problem reduced by 2.2 points, indicating that participants found their HF&NS significantly less.bothersome following treatment. Seven health domains showed significant statistical and clinical improvements, including anxsiety/fear, memory/concentration, menstrual problems, sexual behaviour, sleep problems, somatic symptoms and vasomotor symptoms.

In another study, the same authors evaluated the feasibility of the National Acupuncture Detoxification Association (NADA) five-point ear acupuncture protocol to reduce HF&NS and improve physical and emotional well-being for women receiving breast cancer treatment. Fifty participants completed weekly NADA treatment for eight weeks in small groups (less than five patients). Mean FIF&NS frequency was reduced by 35.9%, perceptions of HF&NS as a problem were reduced by 2.2 points, and statistical and clinical improvements were recorded for anxiety/fears, depressed mood, memory/concentration, sleep problems, somatic symptoms and vasomotor symptoms.
