Women with a family history of breast cancer could be offered preventative medication on the NHS under new plans outlined by the health regulator.
Officials are examining whether women who are at “high risk” of developing the disease should be offered hormone therapy to prevent breast cancer.
Charity Breakthrough Breast Cancer said the consultation is a “historic step” for the prevention of the disease which claims the lives of 12,000 people in the UK each year.
The National Institute of Health and Clinical Excellence (Nice) has launched a draft consultation to see whether drugs tamoxifen or raloxifene should be offered to high-risk post-menopausal women in England and Wales.
A previous clinical trial found that tamoxifen, taken for five years, reduced the risk of developing invasive breast cancer by about 50% in post-menopausal women who were at increased risk of getting the disease.
Another trial found that five years of raloxifene reduces breast cancer risk in such women by about 38%.
Under the new plans, high risk post-menopausal women could be offered the drugs for a period of five years unless they have a history of thromboembolic disease or endometrial cancer.
The new Nice guidelines on familial breast cancer could also see the age that some women are first offered mammograms lowered.
At present, all women aged between 50 and 70 are invited for breast screening but the service could be extended to women aged 40 and up if they are deemed to be at high or moderate risk of developing the disease.
The NHS may also start offering genetic screening to see whether people with a history of breast cancer carry faulty genes that can increase the risk of the disease.
