Research published in The Lancet medical journal last year found the drugs could prevent 1,000 breast cancer deaths a year. Nicola Smith, senior health information officer at Cancer Research
UK, said: “Taking a pill to reduce the risk of breast cancer is an encouraging new option for post-menopausal women at high risk of the disease. “For most women, the side-effects of
anastrozole are likely to be less severe than those experienced with tamoxifen which also reduces breast cancer risk. “It's important for women to consult their doctor if they think
they might be at high risk of breast cancer.” Professor Mark Baker, the director of the centre for guidelines at NICE, said: “The evidence examined by the committee suggests anastrozole will
not only reduce the number of breast cancer cases in these women compared with tamoxifen, but it is also a more cost-effective option.” There were around 55,200 new cases of breast cancer
in the UK in 2014, which is the 150 cases diagnosed every day. It is one of the most common types of cancer in the UK. Symptoms include a lump in the breast, a change in the size or shape of
the breast, dimpling of the skin or thickening in the breast tissue, inverted nipples, rash on the nipple or even discharge from the nipple. Some women also experience a swelling or a lump
in the armpit. Breast cancer symptoms: Women warned to spot PAIN as well as unusual lumps.
