Age plays a significant role in breast cancer screening guidelines. In the UK, women aged 50 to 71 are automatically invited for screening every three years through the NHS Breast Screening Programme. However, women aged 40-49 or over 71 can still request screening. It’s important to discuss personal risk factors with your GP because starting screening earlier may be beneficial for those with a family history of breast cancer. Regular screening helps in early detection, which is key to successful treatment.
