Breast 4a is generally more likely to be benign, with a malignancy rate of around 2%-5%.
Breast 4a refers to the current BI-RADS classification of breast nodules as 4a, which is a classification of breast imaging results from 0 to 6, with the higher the number, the higher the likelihood of malignancy.
Grade 4a is the threshold of benign and malignant, which is generally more likely to be benign, but also has a certain degree of malignancy, and the malignancy rate of grade 4a nodules is relatively speaking around 2%-5%.
However, in order to determine the benign or malignant nature of breast nodules, it is not possible to rely solely on breast imaging, and it is often necessary to puncture the breast nodules and take specimens for biopsy in order to identify the benign or malignant nature.
It is recommended that patients suffering from breast nodules should consult regular hospitals in time and receive standardized treatment under the guidance of doctors.
