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, however, a very survivable disease but 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).For younger women there is no suitable routine screening technique available,.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 has just begun to generate images in post-menopausal women. It is proposed that enhancements to the method will enable it to be applied to younger women as well, enabling the creation 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 岁至 55 岁女性最常见的死亡原因。在全球范围内，每 13 分钟就有一名女性死于这种疾病。然而，乳腺癌是一种存活率很高的疾病，但早期发现肿瘤至关重要。这就需要对所有女性进行全国性筛查计划（除了女性定期自我检查乳房之外）。不幸的是，现有的筛查技术并不是很理想。例如X光检查，只适合老年女性，而且也很不舒服。即使在这些老年（绝经后）女性中，它也有相当高的假阳性率（导致女性进行不必要的活检）和假阴性率（换句话说，它漏掉了一些肿瘤）。对于年轻女性来说，没有合适的方法现有的常规筛查技术。本提案的目的是继续研究基于 UWB 雷达的新成像方法。它会向乳房发出短脉冲无线电波并监听反射 - 这些无线电波完全无害，成像过程快速而舒适。目前，这种新的成像技术还处于起步阶段，刚刚开始生成绝经后妇女的图像。建议对该方法进行改进，使其也适用于年轻女性，从而为所有女性创造一种廉价、快速且舒适的乳房成像方法。由于该成像方法无害，因此可以经常重复使用如有必要，而且价格非常便宜，可以在全科医生诊所甚至面包车中进行，而不需要去医院。
