This technique is therefore an effective tool for early detection of breast cancer. On a mammogram, breast

16、 carcinomas typically display fine calcification and areas of irregularity. Occasionally, fixation of deep lesions, either to the chest wall or skin, can also be seen.35 There are several advantages to using mammography as a screening technique: 小的腫瘤篩查通過乳房x光檢查可以發(fā)現之前有任何節(jié)點參與。這種技術是早期發(fā)現乳腺癌的一種有效工具。乳房x光檢查

It should be noted, however, that the success of low-radiation mammography depends largely on the quality of interpretation.38 乳房x光檢查檢測比體格檢查更早。技術進步近年來加強

Evidence suggests that metastases occur very early

Therefore, the reduction in breast cancer mortality by screening, an estimated 10% to 30% reduction, provides compelling evidence that early diagnosis and treatment of breast cancer can avert

These methods can be either non-invasive or invasive.除了乳房x光檢查和體格檢查還有其他方法來證實診斷為乳腺癌。這些方法可以是非侵入性或侵入性。Transcript 記錄Ultrasound is a non-invasive way to differentiate whether a possible tumor detected with mammography is, instead, a fluid-filled cyst. Ultrasound can also aid in th
