What does it mean if there is blood flow or no blood flow in a BI-RADS 4A breast lesion?

In general, the presence of blood flow in a BI-RADS 4A breast lesion indicates that there is blood supply within the mass, which is typically a characteristic of living tissue. The absence of blood flow means there is no blood supply within the mass. A detailed analysis is as follows:

1. Presence of Blood Flow

The presence of blood flow in a BI-RADS 4A breast lesion indicates that there is blood supply within the breast mass, which is usually a feature of viable tissue. Breast masses with blood flow may grow faster, but this does not necessarily mean the mass is malignant. Some benign masses can also have blood flow, while some malignant masses may lack blood flow. Therefore, breast lesions with blood flow require further examination and follow-up to determine their nature.

2. Absence of Blood Flow

The absence of blood flow in a BI-RADS 4A breast lesion indicates no blood supply within the mass; however, this alone cannot definitively determine the nature of the breast lesion. Some benign breast masses may lack blood flow, while certain malignant ones may exhibit blood flow. Therefore, breast lesions without blood flow also require further evaluation and follow-up to confirm their characteristics.

If patients experience any discomfort or symptoms, they should promptly seek medical attention at a hospital to avoid delays in diagnosis and treatment.
