Breast category 4b refers to breast nodules that are graded as 4b. Whether a breast nodule is serious or not needs to be determined in conjunction with the pathologic findings.
Breast imaging is graded from 0 to 6, with 0 representing incomplete evaluation that needs to be combined with other tests, and 1 indicating a negative result, i.e., a normal breast. Grade 1 is a negative result, i.e., normal breast, while grade 4 indicates the presence of suspected malignant lesions, with a 10-50% chance of malignancy for grade 4b. A comprehensive judgment is needed in conjunction with the pathologic findings.
If the pathological result of puncture biopsy shows malignancy, it is more serious and requires immediate surgical treatment with adjuvant radiotherapy or chemotherapy, endocrine therapy, targeted therapy and so on. If the pathologic result is benign, regular follow-up is needed.
It is recommended that patients with breast nodules should consult regular hospitals in a timely manner and receive standardized treatment under the guidance of doctors.
