目前,最可靠的乳腺癌筛查工具是乳房 X 线照片。乳房 X 线照相术可以在您或医生用手部感觉到乳房内的微小肿块或早期癌症的蛛丝马迹之前发现它们。这也是为什么新加坡健康促进局(HPB)建议 50 岁以上的女士定期去做乳房 X 线照片检查,即使她们感觉良好。您可以使用综合健保双全计划等医疗保险来支付乳房 X 线照片的费用。
如何进行乳房 X 线照相术
乳房 X 线照相术本质上是对乳房进行 X 光检查。机器使用低能量 X 射线捕捉乳房的成像,并显示其中的任何潜在异常。
乳房 X 线照相术有两种主要类型:胶片屏幕乳房 X 线照相术和数字乳房 X 线照相术(也称为全场数字乳房 X 线照相术)。它们之间的主要区别在于乳房成像的方式 – 是用摄影胶片还是在计算机上进行数字成像。
两种乳房 X 线照相术的检查手术过程相同。首先,一名熟练的技师将乳房放在两块透明板之间并轻轻压迫。接着,专门的 X 射线设备从 2 个角度为每个乳房拍摄 2 张照片。压迫乳房是必要的,这样可以减少乳房的厚度,从而通过减少阴影重叠来提高图片质量。
