Whether his Department has considered the merits of introducing a supplemental ultrasound breast screening examination as part of the NHS breast screening programme.

The answer is no. Mammography is the only screening modality that has been proven to reduce mortality from breast cancer, and is supported and promoted by the World Health Organisation’s international agency for research on cancer. Ultrasound screening may be used within the breast screening programme as part of the triple assessment process.

The Minister will be aware that forms of cancer such as lobular breast cancer are far more difficult to detect with a mammogram than other types of breast cancer. Will he perhaps clarify exactly what guidance his Department issues to primary care trusts on the use of ultrasound screening as part of the triple assessment process? Sadly, in the case of my constituent Lindsay Jackson, mammography failed to detect that form of lobular breast cancer.

I am grateful to the hon. Gentleman for his question. The Department does not issue guidance, but the National Institute for Health and Clinical Excellence does. Its guidance on improving outcomes in breast cancer states that mammography and ultrasound imaging should be available in breast clinics as part of the triple assessment of women with suspected breast cancer. In addition, the guidance states that ultrasound is useful in predicting tumour size and in planning surgery, and that it can complement mammography in differentiating malignant and benign disease. That guidance is the key tool used in making such decisions.
