In a groundbreaking development, a drug once used solely to treat breast cancer is now being offered as a preventive measure for high-risk women.

Anastrozole, originally intended for breast cancer treatment, is now offering new hope to high-risk individuals. Such women typically have a family history of breast cancer or carry genetic mutations that increase their susceptibility to the disease.

Research has shown that anastrozole can reduce the risk of breast cancer in high-risk women by up to 50%. What sets this drug apart is that its protective effects endure long after the treatment regimen concludes, providing a sustained defense against breast cancer.

Notably, anastrozole has become the first drug to go through NHS England’s Medicines Repurposing Program. Amanda Pritchard, NHS chief executive, emphasized the significant impact this risk-reducing option could have on countless women and their families. It offers the potential to prevent the distress of a breast cancer diagnosis, enabling women to lead healthier lives.

The drug functions by reducing estrogen levels in the body by inhibiting the enzyme aromatase, which plays a role in estrogen production.

Anastrozole is available to post-menopausal women with a strong family history of breast cancer. Eligible women are encouraged to consult with their GPs to determine the suitability of this drug as a preventive option.

In England, approximately 289,000 post-menopausal women at moderate or high risk of breast cancer will be offered anastrozole, with clinical trials demonstrating a 49% reduction in breast cancer cases over 11 years among eligible women. Should a quarter of eligible women take up the offer and half of them adhere to the recommended five-year regimen, it is estimated that 2,000 cases could be prevented.

Despite its efficacy, it is important to note that anastrozole may not be suitable for everyone, and some individuals may experience side effects. Nonetheless, this repurposed drug represents a significant advancement in breast cancer prevention and offers a lifeline to women at high risk of this devastating disease.
