  schema:description "DHEA is an adrenal hormone sold as an anti-ageing supplement. The body converts it into oestrogen and testosterone, so it should not be taken by people with hormone-sensitive breast or prostate cancer: it is linked to tamoxifen resistance and to prostate cancer growing despite hormone treatment. A prescribed vaginal form for dryness is a separate matter for your team."@en ;
