What are the diagnostic methods for breast cancer

Whether in China or abroad, the incidence of breast cancer has always been high. In the previous chapter, we also learned about the symptoms of breast cancer. So when we find ourselves experiencing similar symptoms, what kind of examination method will further determine whether we really have breast cancer? The following is a detailed introduction to these examination methods, I hope it will be helpful to everyone.

1. Mammography: It is a classic examination method, which is achieved by using a special mammography X-ray machine. The common manifestations of breast cancer lesions in X-rays are regular or quasi-circular masses, irregular or fuzzy masses, burr masses, and translucent ring masses. In addition, mammography is highly sensitive to small calcifications and can detect some characteristic calcifications (such as clustered sand-like calcifications) at an early stage.

2. Breast B-ultrasound: B-ultrasound scan can distinguish between cystic and solid lesions of the breast. B-ultrasound scan of breast cancer often shows a low-echo mass with irregular shape and uneven internal echoes. Color ultrasound can show blood flow signals inside and around the mass. At present, it is internationally recognized that breast mammography is the most effective means of breast screening. However, the accuracy of mammography in diagnosing breast diseases will be affected by the density of the breast. Young women often show dense shadows throughout the breast and lack of layered contrast because of dense glands and rich fibrous tissue. Therefore, young women under the age of 35 can use breast B-ultrasound as the preferred screening method. In addition, B-ultrasound scanning has advantages in observing axillary lymph nodes.

3. Dynamic enhanced nuclear magnetic resonance: Nuclear magnetic resonance examination is the imaging examination method with the highest resolution of soft tissues. It has many advantages over X-ray and B-ultrasound, such as: reliable diagnosis of multi-center lesions; sensitivity and specificity are both over 90%; dense breasts, deep and high positions will affect the evaluation of molybdenum targets, while MRI is not affected by these factors; images can be rotated or cut in any plane, and can clearly show tiny tumors; tumor microvascular distribution data can provide more tumor functional parameters and treatment response; tumor necrosis and fibrous tissue hyperplasia after neoadjuvant chemotherapy, palpation and B-ultrasound are difficult to truly reflect the scope of residual tumors, and nuclear magnetic resonance has unparalleled advantages over other examination methods in this regard. However, it is not suitable for patients with pacemakers and metal in the body.

The above content is the diagnosis and differentiation method of breast cancer. If you are diagnosed with breast cancer, you should receive treatment as soon as possible. In this way, you can get rid of the troubles of the disease as soon as possible, stay away from the torture of illness, live every day with ease, and be a confident woman.
