Acupuncture may significantly reduce hot flashes and other hormonal side effects of endocrine therapy taken by women with breast cancer, claimed a study, based on a pooled analysis of three clinical trials, on Monday. 

Endocrine therapy helps block hormone signalling that drives some forms of breast cancer. Although a life-saving treatment, up to 80 per cent of women experience hot flashes -- a sudden, temporary sensation of body warmth, flushing, and sweating -- and other side effects after taking it, leading to discontinuation, while elevating the risk of cancer progression and death.
