Towards Early Detection of Breast Cancer in High Risk Population (READ RISK)

2022年2月24日 更新者：University of Aberdeen

Robust EArly Detection of bReast Cancer in hIgh riSK Premenopausal Population Using Novel Lipid Based Imaging Methods

Breast cancer is a major and growing health challenge, and the leading cause of cancer in women. As population obesity rates increase, the number of new breast cancer diagnosis continues to rise. Despite treatment advances, breast cancer remains an important cause of premature mortality, taking women in the prime of life. Although underlying susceptibility caused by mutation in the genes including BRCA1/2 is increasingly identified, current pre-symptomatic screening for the general population and those at high genetic risk remains sub-optimal, with high false negative and positive rates.

Alteration of breast lipid composition has been observed by us and others in patients with breast cancer and is thought to precede onset. We have developed and tested a novel method to allow a standard 3T MRI scanner to perform quantitative 3D mapping of specific lipid molecules in the breast.

We will investigate if this method can detect very early breast cancers, and compare the amount and spread of lipid composition in breast tissue of premenopausal women with very high genetic risk of breast cancer, women with breast cancer and women with obesity.

研究人群

Women with BRCA1/2 genes will be identified and approached by the geneticist and research nurse at the family high risk clinic. Patients will be identified and approached by the breast surgeon and breast care nurse at the results clinic. Women with obesity will be identified through organisation emails, word of month and leaflets in the community health clinic for residents of Aberdeenshire.
