项目摘要

Breast cancer is the commonest cause of death in women between the ages of 35 and 55 in Europe. Worldwide, a woman will die from the disease every 13 minutes. Breast cancer is very much a survivable disease however it is vital that the tumour is caught at an early stage. This requires a national screening programme for all women (in addition to regular self-examination by women of their breasts).Unfortunately the existing screening techniques are not very ideal. X-ray for example, is only suitable for older women and is also quite uncomfortable. Even in these older (post-menopausal) women, it has quite high false-positive rates (resulting in women having unnecessary biopsies) and false-negative rates (in other words, it misses some tumours).There is no suitable routine screening technique available for younger women.The aim of this proposal is to continue research into a new imaging method based on UWB radar. This sends out a short burst of radio-waves into the breast and "listens" for reflections - these radio-waves are completely harmless and the imaging procedure is quick and comfortable.At the moment this new imaging technique is in its infancy and much work remains to be done if we are to reach the ultimate goal of a cheap, quick and comfortable breast imaging method for all women.Because the imaging method is harmless, it could be repeated as often as necessary and because it will be very cheap, it could be based in a GP surgery or even a van, rather than requiring a visit to hospital.

乳腺癌是欧洲35至55岁妇女死亡的最常见原因。在世界范围内，每13分钟就有一名妇女死于这种疾病。乳腺癌是一种非常容易存活的疾病，但是在早期发现肿瘤是至关重要的。这就要求对所有妇女实行国家检查方案（除了妇女定期自我检查乳房外）。不幸的是，现有的筛查技术并不是很理想。例如，x光检查只适合老年妇女，而且很不舒服。即使在这些年龄较大（绝经后）的妇女中，它也有相当高的假阳性率（导致妇女进行不必要的活组织检查）和假阴性率（换句话说，它遗漏了一些肿瘤）。目前还没有适合年轻女性的常规筛查技术。本提案的目的是继续研究一种基于超宽带雷达的新成像方法。它会向乳房发出一束短的无线电波，并“倾听”反射——这些无线电波是完全无害的，成像过程既快速又舒适。目前，这种新的成像技术还处于起步阶段，如果我们要达到为所有女性提供廉价、快速和舒适的乳房成像方法的最终目标，还有很多工作要做。因为这种成像方法是无害的，可以在必要的时候重复进行，而且因为它非常便宜，它可以在全科医生的手术中进行，甚至可以在面包车上进行，而不需要去医院。
