Commonly used auxiliary examination methods for diagnosing breast cancer

There are a large number of breast cancer patients, which causes great pain to patients. The following auxiliary examination methods are mainly used in clinical diagnosis of breast cancer:

Mammography

Mammography is performed using a special mammography X-ray machine. The common manifestations of breast cancer lesions in X-rays include regular or quasi-round masses, irregular or fuzzy masses, burr masses, and translucent ring masses. Mammography is highly sensitive to small calcifications and can detect some characteristic calcifications at an early stage, such as clustered sand-like calcifications.

Breast ultrasound

B-ultrasound scan can distinguish cystic and solid lesions of the breast. B-ultrasound scan 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. Young women under 35 years old can use breast B-ultrasound as the preferred screening method. B-ultrasound scan has advantages in observing axillary lymph nodes.

Dynamic enhanced nuclear magnetic resonance

Magnetic resonance imaging is the imaging examination method with the highest resolution for soft tissue. It is reliable for diagnosing multicentric lesions, with a sensitivity and specificity of over 90%. Dynamically enhanced MRI can be rotated or cut in any plane, and can clearly display tiny tumors. Tumor microvascular distribution data can provide more tumor functional parameters and treatment responses. Dynamic enhanced MRI is not suitable for patients with pacemakers and metal in the body.
