TV presenter Sofie Allsopp, who had a double preventative mastectomy to reduce the risk of breast cancer, said the new daily pill is "fantastic" for those women who would not consider the surgery.
Sofie and her sister, Location, Location, Location presenter Kirstie Allsopp, were told they had an increased risk of developing breast cancer after their mother and grandmother had the disease.
Speaking about whether her sister would consider the pill, she said: "I can't speak for Kirsty whether this would be an option for her but I think it's brilliant for a lot of women and I think it's definitely a step forward in terms of preventative."
Women across Britain with a family history of breast cancer are to be offered drugs on the NHS to help prevent the disease.
Women now have a wider choice and more facts to help them make probably the most difficult decision of their lives.
