A method is described of constructing a simple phantom breast containing an idealised tumour with elastic properties. The transparent tissues are compressed and evidence is adduced to show that with tissue compression the tumour boundary is subjected to a degree of strain the magnitude of which is dependent on the degree of deformation. Excessive compression can lead to fracture of the tumour. A literature survey reveals that malignant tissues are more delicate than normal tissues. The study underlines the need for care when using X-ray mammography with compression to image a cancer bearing breast, in order to avoid disseminating cancer cells via the circulation.
描述了一种构建包含具有弹性特性的理想化肿瘤的简单乳腺模型的方法。对透明组织进行压缩，并提供证据表明，随着组织压缩，肿瘤边界会受到一定程度的应变，其大小取决于变形程度。过度压缩会导致肿瘤破裂。文献调查显示，恶性组织比正常组织更脆弱。该研究强调，在使用加压X线乳房摄影术对患癌乳房进行成像时需要谨慎，以避免癌细胞通过血液循环扩散。
