Women in England and Wales with a strong family history of breast cancer could be offered medication on the NHS to try to prevent the disease.

The National Institute of Health and Clinical Excellence has launched a consultation on whether tamoxifen could be given for up to five years.

If approved later this year, the draft guidelines would be the first of their kind in the UK.

Eluned Hughes from the charity Breakthrough Breast Cancer explains the new guidelines and who the drugs may be suitable for.
