Screening for breast cancer by Ultrasound Mammography or NMR ?
Screening for breast cancer by Ultrasound Mammography or NMR ? Early breast cancer is a curable disease, and the cure rate can reach 90%, so it is the same sentence: regular physical examinations, women over the age of 40 have a combined breast B-ultrasound + mammography examination every 1-2 years, early detection, early Treatment, that’s right!
The good news is that there is no change in the suspicious part. You can continue to follow up and review it after six months without additional intervention.
By the way, I would like to share with you the pros and cons of the three breast cancer screening methods.
1. Breast ultrasound:
Advantages: There is no radiation in the ultrasound examination. The advantage is that it is sensitive to cystic lesions and has real-time performance. It can dynamically observe the elasticity, mobility and color Doppler blood flow of the lesion. For clinically inaccessible lesions, ultrasound-guided biopsy or preoperative positioning can be used. B-ultrasound can show the axillary lesions, which helps to show the dense breast and the lesions in the implanted breast.
Insufficiency: The limitation of ultrasound examination is that the accuracy of diagnosis often depends on the equipment used and the experience of the examiner. The detection rate and sensitivity of microcalcification are inferior to that of mammography. Ultrasound is often difficult to show small lesions or can not reliably distinguish between benign and malignant.
2. Breast molybdenum target:
Advantages: It can clearly display the layered structure of breast skin, subcutaneous tissue, glands and blood vessels, and has a high detection rate of lesions. It can clearly display the direct and indirect signs of lesions, including structural distortions, asymmetric dense shadows, and Small nodules, the sensitivity of the diagnosis of clustered microcalcifications is 95%.
Insufficiency: a small amount of radiation, and breast tenderness during the examination.
3. MRI of the breast:
Advantages: The advantage of MRI is that it is more sensitive to breast lesions, especially for dense breast lesions, local recurrence after breast cancer surgery, and observation of breast prostheses. MRI is better than molybdenum target for the display of special parts of the breast, such as high and deep breast lesions. MRI detection of multiple centers and multiple lesions, observation of chest wall invasion, and display of parasternal, mediastinal and axillary lymph node metastasis are superior to other inspection methods. MRI can accurately distinguish cystic and solid lesions, and dynamic enhanced scanning can understand the blood perfusion of the lesion, which is helpful for the differentiation of benign and malignant lesions. The most prominent advantage of MRI is that there is no radiation.
Insufficiency: The limitation of MRI is that it shows insensitivity to microcalcifications, and this kind of microcalcifications is a reliable basis for the diagnosis of breast cancer. Therefore, MRI cannot replace mammography. In addition, MRI examination is relatively complicated, the examination time is longer, and sometimes it is affected by respiratory motion artifacts, which limits its application to a certain extent. The MRI manifestations of benign and malignant lesions overlap to a certain extent and cannot replace tissue biopsy.
Therefore, the current combination of mammography and ultrasound is the golden combination of breast screening, and MRI is an important supplementary examination method.
Early breast cancer is a curable disease, and the cure rate can reach 90%, so it is the same sentence: regular physical examinations, women over the age of 40 have a combined breast B-ultrasound + mammography examination every 1-2 years, early detection, early Treatment, that’s right!
